Discover the customized ductwork solutions you need.
Here at Imperial Systems, we’ve been manufacturing customized sheet metal ductwork since 2001. With all that experience, we feel proud to call ourselves experts in the industry. However, a lot of the individuals and businesses we serve know that they need a customized ductwork solution, but they don’t know that much about the product itself. This can be a major problem for businesses or individuals who are trying to make a serious investment in their business and its safety, when they are unable to determine exactly what they need and who can best help them reach their goals.
So, we want to share our expertise with you! Discover the practical–and sometimes entertaining–facts about the world of ductwork fabrication and installation.
Interesting Fun Facts About Ductwork
- Let’s start simple: ductwork is one word. Despite the countless times it’s misspelled as two words, it really is just one word.
- Sheet metal bending isn’t as old as you think it is. Manufacturing and production using the material really took off in the late 1800s during the Industrial Revolution, as assembly lines and new machines made it a practical and profitable endeavor.
- Ductwork is an Imperial Systems tradition. In fact, we started as a custom sheet metal ductwork before our industrial dust collectors! With that kind of experience, we’re confident that we’re still the best in the industry.
- There are 3 main techniques for bending sheet metal: Bottoming, Coining, and Air Bending. Each method uses different tools to bend sheet metal for all sorts of purposes… including ductwork.
- Stiffening is a key component to ductwork compliance. In fact, the SMACNA sheet metal standards call for ductwork of different gauges to be stiffened to ensure it will be durable and not warp during operation.
- Round ducts are stiffened differently than rectangular ones. Round ducts receive stiffening ribs at equal intervals. Rectangular ducts receive cross-braking and beading techniques, depending upon the machinery used and the intended application.
- We offer HUNDREDS of different ductwork components. We know different parts are necessary for different applications; you should know that we’ve always got you covered. You can check them all out in our full catalog.
- Whether you’re a food processing company or a major basket maker, we’ve got you covered. That’s right, baskets. When the Longaberger Company needed new, highly efficient ductwork for their new building, they reached out to Imperial Systems because of our prices, services, and expertise.
- Fabricated Gore Elbows are our most common elbow. Thanks to their versatility and the adjustments that can be made to the radius based on application, we use this elbow in virtually every industry.
- Our Floor Sweeps are hands free. To operate the hinged door that seals off the air flow when not in use, we added a lever on the side of the door that can be operated by foot.
- Heavy wear applications don’t slow us down. Our heavy duty flat back elbows are a square constructed elbows with a 10 ga. housing and a ¼” plate back which can be either welded solid or bolted for replacement without removing the whole elbow. This heavy duty construction makes them perfect for the toughest of applications.
- The most common ductwork material is carbon steel, but it isn’t your only option. Our fully welded pipe comes in galvanized, stainless, and painted.
- You could crawl through our ducts… but you probably shouldn’t. All of our welded pipe is smooth inside and free of burrs and rough edges. So, if you’re on a super spy mission, you don’t have to worry about skinned knees. But unless you actually on a secret mission, you should probably keep your feet on the ground.
- Good ductwork is dust collection’s best friend. The ductwork of an industrial dust collection system connects its hoods, air cleaning device, and fan. You can have the best device in the world, but if your ductwork is poorly constructed or improperly sized, you’re not going to get the results you need.
- Ductwork for dust collection is different than ductwork for HVAC or fume extraction. Tapered systems are typically used with dust collectors, while plenum systems are used more often for HVAC systems, and occasionally for fume extractors.
- When choosing ductwork for industrial dust collection, you need to answer three key questions. Industrial Ventilation, Inc. recommends asking the following three questions (and we completely agree.) What exhaust volume is required at each dust collection point? What particulates are being collected? What are the conveying velocity requirements?
- Dirty ductwork could be costing you. Over time, debris can accumulated in the ductwork of industrial dust collection exhaust systems, decreasing their ability to perform at the optimal level. In fact, a buildup can lead to a loss of up to 42% efficiency! Poor performance can lead to major problems, including health problems in employees and higher running costs.
- It’s not just the dust collector… your ductwork has to meet NFPA standards too. If your industrial duct system is being used for dust collector exhaust, it is imperative that it meet these standards. Ensuring that your system has adequate conveying air velocity for the load it will be handling is imperative to avoiding debris buildup in ducts and reducing the risk of explosion.
- You don’t necessarily have to look inside ducts to identify areas of dust accumulation. In fact, there are a number of telling visual clues you can look for, including:
- A main duct diameter that doesn’t enlarge after branch junctions
- A branch duct joining the main duct at a T junction
- A main duct that is blanked off
- A ductwork system that includes too much flexible hose
- A smaller diameter duct abruptly joining a larger diameter one
- A duct blast gate that isn’t locked in position
- You don’t have to be an expert in ductwork. Although these facts are certainly a great starting place, you don’t need to be an expert in the world of customized ductwork to get the products you need to keep your business running safely and efficiently. Instead, you can work with the experts at Imperial Systems. Just tell us about your business and what needs you are trying to meet; we’ll help you select or design the perfect solution for you.
Now that you’ve learned a little bit more about industrial ductwork, you may be wondering if your company’s ductwork is actually up to par. Or, you may know that it’s time for an upgrade or other major change. No matter what stage you are in, let us
