Can You Weld Rolled Steel?

A Welder at Work

Can you weld rolled steel

When it comes to metal rolling and welding, steel is one of the most common materials that is custom rolled. Hot rolled steel is often preferred because it tends to be cheaper than cold rolled steel. A big question people pose is, “Can hot rolled steel be welded?” The simple answer is, “Yes.” Actually both types of steel can be welded, though cold rolled steel is often harder because it is smoother and welding it can discolor it if you’re not careful. Also, what makes welding either types of steel difficult is mill scale. This is the oxide layer that forms over the steel when fabricated. The mill scale can slow the flow of the weld pool creating poor appearances or contours.

Some ways to make welding rolled steel a bit easier include:

  • Slowing the travel speed, though this will slow down production and may not be an ideal option.
  • Use gas-shielded welding processes. 
  • The best gas-shielded process is metal arc welding using solid wire.
  • The next best route is gas-shielded metal arc welding using metal-cored wire.
  • The final option is using flux-cored arc welding with gas-shielded wire.

What is difference between hot rolled and cold rolled steel?

When you’re weighing between welding cold rolled vs hot rolled steel you need to know what the difference between the two types of steel are. The primary difference between the two is the fabrication process between the two. As the name implies, hot rolled steel is fabricated using heat. It is pressed at temperatures over 1,700 degrees. On the other hand, cold rolled steel is pressed at or near room temperature. Cold rolled steel will be shiny and smooth and often hardened by the fabrication process. This makes it a little more difficult to weld because it’s easier to cause discoloration than with hot rolled steel. Hot rolled steel is a little softer and the welds will be less apparent. If you are looking for metal rolling and welding services, you can count on the team at Haltom Industries.

Welding rolled metal

With metal rolling and welding, some metals are better than others. While hot rolled and cold rolled steel are often difficult to weld, other materials are very reliable. Some metals like low carbon mild steel, aluminum and stainless steel require the fewest pre- and post-weld operations, so the weld is less likely to fail. Of these low carbon mild steel is one of the best to use. It is commonly used so it is abundant, and current welding technology and techniques are easily adapted to its use. It’s also more ductile than other types of steel. 

Welding cold rolled steel to stainless

Metal rolling and welding can create several complications, especially if you are trying to combine two different types of materials like cold rolled steel and stainless steel. Sometimes dissimilar materials have to be used for cost considerations or service condition requirements. Often combining different materials can be more economical than building with just one material. This often occurs in power generation facilities as well as in mining operations. Whenever you’re welding different types of materials together you’ll want to select the right filler materials and use proper welding techniques. Matching the filler material is critical. It has to be chemically compatible with both materials for a solid, lasting weld.

Is hot rolled or cold rolled steel easier to bend?

Because of the processes in which these types of steel are fabricated, they have various levels of hardness. Cold rolled steel, fabricated near or at room temperature, is harder than hot rolled steel, and thus less easy to bend and shape. Metal rolling and welding applications may be limited with cold rolled steel. On the other hand, cold steel is easier to craft to exact specifications, and works best in applications where strength is more important than flexibility.

Does cold rolled steel rust?

While cold rolled steel can corrode and rust when being shipped or warehoused, most manufacturers finish it out with oil. These oils are specially designed as rust-inhibitors. Along with oil, rust can be prevented by storing the steel in dry, climate-controlled environments.

Why is cold rolled steel more expensive?

Even though cold rolled steel has many advantages over hot rolled steel, especially when it comes to toughness, it is normally more expensive. Much of the expensive is due to the manufacturing process itself. The metal is harder to manipulate and takes more time to fabricate than hot rolled steel, so it costs more to process. The difficulty of manipulating cold rolled steel also tends to cause projects using it to take more time, and this can make the projects more expensive.

Can You Replace Ductwork Yourself?

HVAC Ductwork.

Can you replace ductwork yourself?

From damage caused by pests to age and wear, there may come a time when your HVAC ductwork will need to be replaced. While you might consider installing ductwork yourself, it’s not recommended. Your ducts manage your HVAC system’s airflow and energy efficiency. If it’s improperly installed it’s possible you can harm your system’s efficiency. This is true for replacing both residential and commercial ductwork. 

When it comes time to replace your ductwork, you not only want to hire professionals you want to make sure they are using the best materials to install them. Haltom Industries recommends using KwikFlange vacuum flanges to connect round ducts. These flanges are easy to install, reusable, and handle high vacuum environments and resist pressure in the range of 1×10-8 Torr. Find out more about KwikFlange and our other services in , TX by calling 817-770-0811.

Should ductwork be replaced after 20 years?

As with anything, your HVAC ductwork will eventually wear out and need to be replaced. Even metal ductwork after about 15 to 20 years can get worn. Metal ductwork can rust if it isn’t properly insulated. Flexible ductwork is susceptible to tears or leaks or even damage caused by pests. When you have your HVAC system inspected as part of regular maintenance, you may want to have your ducts checked for broken seals and leaks as well. Get repairs made as soon as possible as leaks will affect your system’s efficiency.

Is flexible ductwork good?

Flexible ductwork is often installed in homes, especially, because it’s cheaper than metal ductwork. This type of HVAC ductwork has its advantages and disadvantages. It’s easier to install, so labor and materials costs will be lower than metal ductwork. It’s also useful to install in tight spaces where metal ducts won’t fit, so it’s a good option where there are sharp corners and angles. At the same time, flexible ductwork can easily get pinched or twisted, which restricts airflow. It’s also susceptible to getting punctured, and can become brittle and break. Although initially cheaper to install, you may have to replace it more often than metal ducts.  

How do you connect ductwork together?

For professionals connecting metal HVAC ductwork is generally an easy task. Even skilled DIY-ers can replace sections with some ease, though we don’t recommend replacing all your ductwork yourself with some professional guidance. Here is a guide to install round metal ductwork.

How to connect HVAC ductwork

  • Install HVAC duct damper: You’ll first install the dampers in the register. The dampers regulate airflow.
  • Assemble metal ducting: The duct pipes can be assembled almost like a zipper. The edges of the metal are held together and then apply downward pressure to press the seam like a zipper.
  • Use a hole cutter in tight spots: When replacing ductwork in a tight spot, open holes using a sheet metal hole cutter.
  • Use draw band connectors to connect replacement pieces to fitted parts: These connectors are especially useful when installing pipe between fixed parts. You just need to overlap one side and create a butt joint on the other and complete the butt joint with the connector. 
  • Caulk take offs: Use caulk rather than tape on the connections between trunk lines and take-offs or elbows.
  • Use support brackets to reduce movement and noise: Support brackets will hold pipes in place. You also want to use three screws to screw the pipes into the joist hanger to keep them from rattling.

How to install HVAC duct boot

Duct boots are used in HVAC ductwork to convert the duct to a vent. They are commonly used for floor ducts and registers. To install the boot, you’ll attach the boot to the end of the duct piping and press it against the subfloor where you plan to install the register. You’ll mark a rectangular space around the boot and cut a hole in the subfloor where it is marked. The boot is centered under hole and make sure the tabs are flush with the subfloor. Screw the boot into place and then secure the floor duct to the floor.

How much does it cost to install new ductwork?

Costs will vary to install new HVAC ductwork. Much of this will depend on the amount of ductwork installed. Ductwork runs between $35 to $55 per linear foot, so to put in new ducts in a single-family home will run between $1,000 to $5,000. Really challenging jobs may run higher, up to $15,000 or more. To install HVAC and ductwork together will cost more. A new HVAC system may cost anywhere $4,000 to $12,000 to install.

What is Metal Rolling?

Metal rolling can create ductwork

What is Metal Rolling?

In the metalworking industry, metal rolling is a popular and integral process. It is important to note that rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls. Essentially, it’s a process that is similar to using a rolling pin to roll out dough. In fact, the rolling itself is graded according to the temperature of the metal that has been rolled. This is worthy of mentioning because if the metal’s temperature is above its recrystallization temperature, then the procedure is recognized at hot rolling. Conversely, if the metal is rolled below the recrystallization temperature, then it’s known as cold rolling.

What is the Principle of Rolling?

Metal rolling has a long and storied history. As a matter of fact, Leonardo da Vinci is noted as the first person to sketch the rolling mill. The earliest rolling mills date to 600 BCE. The principle of rolling is simple. Metal stock is passed between one or more rolls. These rolls reduce the thickness of the metal in a uniform fashion. At the end of the day, there are many different types of rolling processes. These rolling processes include ring rolling, roll bending, profile rolling, roll forming, and controlled rolling.

What is Hot Rolling and Cold Rolling Process?

As previously mentioned, there are two distinct sets of processes for rolling metal. These processes are known as hot rolling and cold rolling. In each of these processes, the temperature of the metal is central to the procedure. If the metal is rolled at a temperature above its recrystallization temperature, then it is known as hot rolling. If the metal is rolled below its recrystallization temperature, then it is known as cold rolling. Speaking specifically to how popular hot rolling is compared to cold rolling, hot rolling processes more metal than any other manufacturing procedure. Rolling mills are able to rapidly maneuver metal, usually steel, into important building elements such as structural steel.

What are Rolling Defects?

In the metal manufacturing process, there are two main types of rolling defects. The first of these two types is surface rolling defects. The second type is known as internal structural rolling defects. Surface defects result from impurities and inclusion in the material surface. These include roll marks, dirt, rust, and other causes related to the previous treatment of the metal itself. Internal structural defects, in contrast, are typified by wavy edges, zipper cracks in the center of the strip, edge cracks, and alligatoring.

What is Roll Separating Force?

Roll separating force is defined as a force that is applied to rolls in a vertical direction. This force is central to how a rolling mill operates. As a matter of fact, a rolling mill is distinguished by the maximum values of its roll separating force and the resulting torque. If you have a commercial property, and you have a single-ply roof, it may be time to secure a proper roof inspection. Getting a roof restoration will help your building perform well for years to come.

What is Metal Rolling Process

Would you like to learn more about the hot metal rolling process? Please review the following bullet points to learn more.

  • The starting metal is usually comprised of large pieces of metal. These pieces of metal could be slabs, blooms, and billets.
  • Before the heating can begin, the metal material must be at room temperature.
  • Next, particularly in larger metal manufacturing firms, the material is heated in a gas or oil-fired soaking pit. In a smaller operation, the material will be heated using induction heat. 
  • As the material receives this attention, the temperature must be monitored in order to ensure that the temperature remains above the recrystallization temperature.
  • Once the material has achieved the desired temperature, it can then be hot rolled.

If you require custom rolled metal products, it’s important to secure a consultation with an authority in customizing large metal ducts.

What is Metal Sheet Rolling Machine

It is important to differentiate these various machines and processes. A metal sheet rolling machine will roll different kinds of metal sheets into a conical aspect. A plate rolling machine can also be known to be a roll bending machine, a plate bending machine, or a rolling machine. There are different types of technology that are used to roll metal plates. These machines are known to be four-roller machines and three-roller machines.

Rolling Metal Without a Roller

The roll bending machine is utilized for forming equipment into a cylinder, cone, and curved shape. This machine operates by utilizing the principle of the three-point forming circle. The relative position change and rotational motion of the working roll enable the workpiece to be formed without a traditional roller.

Metal rolling can create a variety of shapes.

Metal Rolling and Welding

There are many different metal rolling and welding companies in the United States. It is important to note that for the fabrication of ducts, you will want to search for a company that specializes in such work. There are many specialties to metal-working which is why it’s important to be discerning.

Why Use Oval Duct

Oval Air Ducts Ready for Installation

Why use oval duct

When installing ductwork in your facility, you have a variety of options available to you including rectangular ductwork, spiral cylinder ducts and oval ductwork. Many businesses and manufacturers are beginning  to choose oval ductwork over other systems. Below is a list of reasons why you might consider oval ducts for your facility’s HVAC system.

Reasons to use oval ductwork

  • Improved air flow: Oval or round ducts can be longer and require fewer joints, which improves air flow and energy efficiency.
  • Ease and speed of installation: Because oval ducts require fewer joints, they are easier and faster to install.
  • Less expensive: Not only are oval ducts easier to install, they also cost less to install. You can save as much as 67% on installation over other types of duct systems.
  • Less noise production: Oval ducts transfer less noise from fans and motors than other duct systems. The noise can be further reduced with insulation.

If you are installing new ducts and are interested in oval ductwork in Haltom City, TX, and surrounding areas, give the experts at Haltom Industries at call at 817-770-0811. We specialize in fittings and flanges for oval ducts. 

What are the types of ducts?

Ducts are classified as either conditioned air ducts, recirculating air ducts or fresh-air ducts. Conditioned air ducts send the air from the air conditioner to the conditioned area, while recirculating ducts take the air back to the air conditioner. Fresh air ducts are used to circulate fresh air into the air conditioning system from outside.

The ducts usually have one of three configurations: round, square or rectangular. Round or oval ductwork tends to be the most efficient when it comes to airflow, but rectangular or square ducts tend to fit better above ceilings or inside walls.

How are ducts made?

Whether oval ductwork or rectangular ductwork, the ducts can be made from a range of materials, though traditionally they are made from sheet metal. Some of the materials available are galvanized steel and aluminum, fiberglass and plastic. The material is shaped into ducts using automated machines. The shaping process will vary depending on the type of duct made. Oval metal ductwork is more common than fiberglass or plastic.

What is rectangular duct?

Rectangular ducts are commonly used in commercial buildings, although oval ductwork and round ducts are also beginning to be used more frequently. As the name suggests, rectangular ducts are shaped into rectangles. It often requires several joints to install, which can decrease air flow, but fits well inside walls and on ceilings and adapts easily to various building heights. These ducts can create a warmer indoor environment, and require less maintenance than round or oval ducts. 

Why ducts are normally rectangular cross section?

If you have rectangular air ducts, cross sections will also be rectangular so the sections will fit together correctly. While oval ductwork is becoming more and more popular, many duct systems in place are rectangular. Sometimes rectangular ducts will be required because of the building’s height. They also often fit more easily in walls or on ceilings, and connect better to the main duct. 

Is round ductwork better than rectangular?

Round or oval ductwork is generally overall a better choice for a duct system over rectangular ductwork. Oval duct air flow tends to be better than that of rectangular ducts, making the oval ducts much more efficient. They also tend to cost less than rectangular ducts, and are easier to install. When you’re designing a workspace, round ducts are recommended because they are much quieter than rectangular ductwork. 

While generally better than rectangular ducts, round ducts do have their disadvantages. One major disadvantage is that they take up more height than rectangular ducts. They won’t fit it tight spaces. In some cases, it may also be difficult for round ducts to fit onto the main duct. They are also less efficient with low pressure systems.

Although rectangular ducts fit better in tighter spots, they also make much more noise than round ducts, which can be a big disadvantage, especially if you are specifically trying to make a quiet work area. They also require more material and more joints which makes them cost more to buy and install.

While round ducts have more advantages, what sort of system you choose may depend on your building itself, especially if there are height restrictions to consider. Your HVAC system will also determine the type of ducts you’ll need. Some systems will just work better with one or the other types of ducts.

Whichever type of ductwork you choose, you will need to keep it clean and free of clogs for the HVAC system to run smoothly. Keeping ducts clean is as important as getting rid of clogs in your plumbing system. There are plenty of highly skilled plumbers for clogged drain cleaning in Mesquite, TX, and in the surrounding areas for you to choose from.

What Is the Best Gasket Material?

Gasket Material Made of Metal

The Right Materials for Your Needs

Owning a high-demand appliance or vehicle means that you are going to be responsible for quite a bit. It’s not enough to take care of the exterior, but all the interior moving parts as well. One piece of equipment that many hear about but may not fully understand is the gasket. This is a piece of rubber or rubber-like material, that is used to help lock and seal certain junctions in your ductwork, your car engine, or in other areas. It’s used to seal the connection between two adjoining pipes and is much more necessary than you may be aware of. This simple piece of material helps to prevent leaks and other catastrophic events. For more information about gaskets and gasket material in , TX, dial 817-770-0811 to connect with Haltom Industries today.

Exhaust Manifold Gasket Material

How to Choose Gasket Material

What actually is a gasket? This a piece of material or rubber that is placed as a seal between two flat surfaces. There are many gasket types and materials because there can be a need for one in several different appliances. A gasket may be needed to seal two joining pipes. Gaskets are often used in vehicle engines for sealing purposes. 

For homes and office spaces, the most common areas you’ll need a gasket are in your plumbing or in the ductwork. In these conditions and spaces, the best option you might need is EPDM gaskets. These are rubber-like pieces that provide incredible sealing and compression ability. What that means is, they will be able to be flexible when necessary, but still durable when necessary. 

So how do you pick the right one? Well, finding the right gasket is going to depend on what your needs are. If you need a gasket for ductwork, you are going to want something that is flexible and has the ability to compress easily. You don’t want something with little to no give. If you need a gasket for your car engine, you are going to need something that can withstand high temperatures and potentially harmful chemicals. That gasket needs to be able to handle all of that and last. Choosing a gasket material is like choosing an air conditioning company in Salt Lake City, UT. You could pick the first one that catches your eye, or you could rely on expert knowledge.

Different Gasket Material Types

Just as there are several options for gasket types, there just as many options for materials. It can seem overwhelming trying to find the right type while making sure it is made from quality gasket materials. That’s why it’s best to rely on expert contractors and technicians when you can. For that, you can always turn to Haltom Industries for help. 

  • Cork: These gaskets are highly compressible and flexible, making them perfect for situations involving oil, fuel, or solvents. When combined with elastomer bindings, a cork gasket can provide incredible sealing ability. 
  • Metal: Metal gaskets are heavy duty and able to withstand high-intensity temperatures, exposure, and chemicals without risking damage. They are often used in turbines, exchangers, compressors and more. 
  • Rubber: Rubber gaskets are flexible, pliable, and incredibly reliable. They are used in a variety of household uses including ductwork and other areas. Rubber is great for preventing liquids from leaking.

Depending on the size and scope of the project, as well as your budget, the cost for any gasket material is going to vary. If you are working with a contractor, there will more than likely be service fees included in the price, but generally speaking, the price for gaskets is relatively low. When it comes down to the how, as in how to choose a gasket material, that is also going to depend on your needs. Connect with a Haltom Industries today to learn more about gaskets and what you need for your home. Dial 817-770-0811 to get started.

What Is A Flange Gasket?

Assortment of Gaskets

Learn More About Gaskets

A flange gasket is used to fit or join two sections of pipes together with each pipe typically having a flared area where the gasket attaches to. There can be many types of flange gaskets from standard, custom, ring, full face gaskets and more. They can be non-metallic, semi-metallic or metallic in material composition. Flange gasket thicknesses can vary as does shape according to what design it will be used for. Consider this basic flange gasket selection guide which can assist you in determining what type and materials of gaskets would work best with your home or business. If ever in doubt, consider further research and the help of a qualified professional.

How does flange gasket work?

A  flange gasket is used in order to create a seal between two flange faces at different conditions, pressures, and temperatures. There are microscopic spaces and irregularities on flange faces that different types of gaskets will fit into for a tight seal against both liquids and gases.

What is the difference between gasket and packing?

A flange gasket is any mechanical seal that fills the space between two objects usually to prevent leaking between them while under compression. Packing can technically be used as an action verb for gasket use. However, they are also used as a term as materials that also are used to provide compression seals for pumps and valves. They can also be referred to as valve packing, pump packing, compression packing, braided packing or mechanical packing.

What’s the best gasket material?

Gasket materials are made and manufactured for different purposes and can range in advantages for various situations. Some may even be made for specific environments which it’s why it’s not realistic to determine any best material as they are made differently to fit a specific scenario. It’s better, therefore, to consider common gasket materials with a type of use. With silicone rubber materials you’ll have resistance against high temperatures and weather while also touting exceptional electrical insulating properties. Due to these advantages, these are suitable for outside areas. With a neoprene sponge, you’ll have a material that’s chemically inert which makes it suitable for industrial applications when the use of oil, petrol or chemicals are used. They can repel moisture, dust, and water as well as withstand high compression levels. A material that works with aggressive chemical and fuels is vitrol FKM. This material is known for its high resilience properties which makes it a great choice to be used with these substances.With neoprene rubber, you’ll have a high resistance to ozone and weather which make them great for outdoor and marine applications. They are good for use of refrigerants, animal and vegetable oils. As of such another popular gasket material that is used for general use all around is natural rubber. Although it’s water resistance and can withstand mild chemicals, tearing and abrasion it should not be used near fuel. With nitrile butadiene rubber (NBR) you’ll see most effective use with oil, petroleum oils, water, and silicone greases. A material that is used with oil and fuel pumps is Cork. This material is known to be flexible, solvent resistant, resist high levels of compression and have high anti-vibration characteristics. Finally, a strong fibrous material known for high heat and chemical resistance is asbestos. Since this material is harmful there has been a rise in non-asbestos reinforcement fibers that can take its place.

What are the types of flange?

Here are some example of flange gasket types and uses.

Flange Gasket Types and Uses

  • Spiral Wound (used for higher temperatures and pressures)
  • Ring Joint, styles R, RX, BX (used for RTJ flange faces)
  • Non-Asbestos, full and raised face (used for low pressure and temperatures, non-critical applications)
  • Kammprofile (used for  equipment that has high movement like large vessels or heat exchangers) 
  • Jacketed (used in cases of high temperatures and pressure, high load exhaust and heat exchangers)

What is the difference between Series A and B flanges?

A Series A flange is thicker and heavier than a series B flange yet the latter will incorporate more holes, be lighter and cheaper.

What does flange class mean?

Classes of flange basically determine the temperature and pressure ratings of a particular series of flange. For example, a Class 300 flange can handle more pressure than a Class 150 one since the former is constructed with more metal and can withstand higher pressures.

What Are the 4 Types of Welding?

A Picture of a Welder in a Factory.

Which Type of Welding is Best?

One of the cool things about welding is that its able to transform the look of metal. If you are wanting a long metal tube or a metal circle, you are able to achieve different shapes and designs. In order to get a certain design or shape, many people want to know how welding is done. The most popular classifications of welding are arc and torch welding. Arc welding is when an electrical arc is heated to weld metal or metals together. Torch welding is when a oxyacetylene torch is heated to weld metal or metals together. By using either arc or torch welding, you can heat up metal and are able to melt them with other types of metals. So when someone asks, “How welding works.” You can explain that metal is heated to a high temperature with certain tools and then the metal is melted together. There are a lot of welding methods, but these four types of welding methods are pretty popular.

  • MIG (Metal Inert Gas) Welding: In terms of being an easy form of welding to learn, MIG welding is one of the easiest methods. Using shielding gas, MIG welding uses a metal electrode to heat up metals in order to melt them together.
  • TIG (Tungsten Inert Gas) Welding: TIG Melding uses shielding gas in order to heat up the metal, but instead of using a metal electrode, a tungsten current is used instead.
  • Shielded-Metal Arc Welding: This method of welding is also known as stick welding. Using a stick electrode welding rod covered in a metal coating, a gas shield forms as the metal is heated.
  • Plasma Arc Welding: When using plasma arc welding, the electrical current used to heat up the metal goes through a nozzle, which then goes through a protective gas.

Which is Better MIG or TIG Welding?

When we discuss welding, the most common welding methods that come up are MIG and TIG. Both MIG and TIG use filler materials to connect metals, as well as heat metals until they are a liquid. While they have these similarities, they are different methods of welding. The method of MIG is when a metal wire connected to a metal electrode is fed into a machine that will meld metal together. TIG, on the other hand, runs an electrical current through the metal using a tungsten electrode. So what’s the difference between MIG and TIG welding? MIG continually feeds a metal wire and TIG uses rods that are slowly fed into a weld puddle. Whats stronger MIG or TIG? It is honestly going to depend on what you are welding because different jobs will ultimately require different types of welding methods.

Welding Vs Soldering

Welding and soldering are always methods that are used interchangeably, but these two techniques are actually different from one another. They both join metal together and use filler materials, but their methods are different. When it comes to welding, you have to use two metals that are alike. When connecting two pieces of metal together, welding needs high temperatures to do so. Different metals can be used when soldering, and low temperatures are used in order to join the metals together. Welding is a lot stronger than welding; welding can be used on cars and soldering can be used on electronic devices. Both of these techniques are going to be used for different projects and will never be used in place of the other.

Welding and Fabrication

A Person Performing Welding Work.

What Do I Need To Weld?

Fabrication and welding usually go hand in hand, as welding is a part of the fabrication process. Fabrication is when something is assembled, shaped, bent, or cut in a metal project, and welding is when two or more pieces of metal are joined together using high temperatures. If you are wanting to weld something, there are a couple of things that you will need. You will need to choose what type of welding method you are going to use. There are a lot of welding methods, all of them will require a certain level of skill, so if you are a beginner, you should choose a method that is easy for beginners. Once the methods is picked, you need the proper equipment. You will need a welder and welding wire, as well as gas, welding cart, welding pliers, awl, magnet square, chipping hammer, and right-angle grinder, as well as the proper safety gear like a welding helmet, welding gloves, safety glasses, and a fire resistant jacket. When you have chosen the method, have all of your equipment, and safety gear, you can start welding. If you are looking for rolled metal for welding purposes, call Haltom Industries! Just like you wouldn’t call someone inexperienced for air conditioning installation, you wouldn’t call someone who doesn’t know how to weld.

Your ac system is essential for that oh so longed for chill during a hot day and that highly appreciated cozy warmth during the freezing seasons.  Contrary to belief, your duct system won’t last forever. Just like many things with age comes wear and damages that require upkeep and maintenance. At times, unexpected influences can shorten the lifespan of your unit and cause a need for repairs and new air duct system installations. It’s essential to become familiar with the components of your ac duct system and understand how it works so you can have relevant fixes when the time comes to switch it out.

What is an Air Duct System?

An air duct system consists of many channels through which air is cooled and heated throughout a property.  Airflow can expel warm or stale air as well and features supply air, exhaust air and return air with the first being part of ventilation air. Ducts can engage in indoor air quality,  thermal comfort and provide focal cooling which can warm and sift frameworks. Depending on the need, there are diverse systems of ductwork that can be implemented into a home or business.

Air Duct System Components

The components of your air duct system are essential in order for you to find out where problems may lie in case you require an air duct system installation for the future. The first is your ductwork which comprises a system of ducts in which your HVAC flows air in and out of the property. Next, are the vents which transfer this air into the individual rooms through outlets. Your thermostat is something that everyone is familiar with and is usually the most visible and accessible part of your HVAC system. Here you can program your system for the desired schedule for temperatures or make adjustments throughout the day according to your preferences. A large part of your system that requires space is the furnace, which is usually placed in a closet, basement or attic. It processes heat through sources like electrical resistance, a heat pump, combustion or solar energy. A heat exchanger switches on when the furnace is activated and pulls cool air in order to heat and circulate it through the ducts. The evaporator coil in turns does the opposite and cools air when the thermostat is set to lower temperatures. The condensing unit is typically filled with a refrigerant gas and is connected to the evaporating coil and conducts heat exchange with exterior air.  The refrigerant lines than carry the refrigerant gas to the condensing unit and return it to the evaporator coil in liquid form.

How Often Should I Get my Air Ducts Cleaned?

You should engage in air duct system cleaning according to the National Air Duct Cleaners Association every 3-5 years. If you have pets or smoke it may be recommended to engage in the cleaning even earlier depending on your circumstances.

Should Ductwork be Replaced After 20 Years?

On average duct work begins to deteriorate by 15 years old which can lower energy efficiency on your system. The maximum lifespan is typically 20-25 years yet if you see signs of damages replacements are essential.

Do I Need to Replace Ductwork?

If you have aging ductwork or have had ducts installed 30 years prior than they simply will not work with the high efficient HVAC technologies of today. Ducts actually expand with the heat in the winter and contract with the cool of the summer. As heating pulls ductwork or seams apart than a leak may form and repairs or replacements may be necessary. Another reason for replacements could be poorly joined ductwork with aluminum or missing screws. What’s more, uninsulated ducts can rust as condensation will form on the metal material during the summer which can cause holes and breakdown system connections. Ultimately, poor support can cause a system to buckle, sag or block air flow. Make sure to have your systems properly inspected, even with areas on Angle rings to determine if a new ac duct system installation is needed or even a Roof restoration service.

How Long Does it Take to Replace Ductwork?

It depends on the extent of the work yet on average an air duct system installation can take 1 to 2 days. If the ducts are more accessible is could be less than a day or if the area is large it can take a couple of days.

What Causes Ductwork to Collapse?

Damages to part of a system can be caused by a range of impacts and age. There could be pests that can chew on work, corrosion,  leaking or indirect damage from debris from new constructions or renovations. Yet the main cause of collapse can be old ductwork, poor repairs or installations.

Signs You Need Duct Repair

Dust Around Your Air Registers Indicates a Need for Cleaning or Duct Repair.

Ductwork is an indispensable component of an HVAC system. Without quality, well-maintained air ducts, your HVAC would have no means to distribute conditioned air. Unfortunately, many home and business owners alike take their ducts for granted, and skimp on necessary, periodic maintenance. Air ducts allowed to deteriorate, however, will impede the functionality of your HVAC, make it work harder, and cost you money on monthly bills. To preserve both your ducts and the overall functionality of your HVAC, pay attention for the signs that indicate a need for duct repair.

Strange Odors

Odd or unpleasant odors stand as one of the clearest signals for duct repair or maintenance. If you ever notice a bad smell that seems pervasive throughout your facility, it must have its source in your air ducts. Bad smells can indicate different problems, including the presence of mildew or mold, or even a dead animal. Regardless, call a professional technician to come check it out.

Airflow Problems

Many things can lead to poor, restricted, or non-existent airflow from your HVAC. If you’ve noticed no airflow whatsoever, you either have a major leak, frozen AC coils, or a large obstruction somewhere in your ducts. To isolate the problem, you can identify rooms where the issue seems particularly prevalent. If you have airflow, but it seems restricted, there exist any number of possible causes. For example, air vents could have become blocked by furniture or rugs, or a nesting animal inside of your ducts.  Your ductwork might also have punctures, or become disconnected. Regardless, the easiest way to get to the bottom of airflow issues is to call for professional help.

Dents or Punctures

If you have exposed ductwork, make sure to perform regular visual inspections for any signs of damage. To preserve the condition of your system, make sure that nothing rests against or hangs from the ducts. Dents or small punctures may not seem like a huge problem, but they will nevertheless weaken your system and negatively impact its performance.

For a solution to any of these problems, call a local, trusted HVAC or ductwork contractor. For angle rings, Kwik Flanges, or any other component of a commercial duct system, trust in Haltom Industries. We’re a national leader for ductwork connections, and stand ready to serve at 817-770-0811.
