If you’re the owner of a manufacturing facility, controlling airborne dust and contaminants is crucial for keeping your employees safe and healthy. There are a few ductwork options you can consider to help you maintain proper airflow quality. When evaluating your options, you’ll need to keep in mind the costs for installation and maintenance. Here’s a guide to understanding commercial oval ductwork options.
Spiral Duct Products
Spiral ducting is an inexpensive pipe ranging from 16 to 36 feet long. The cost of spiral ductwork installation is around half the cost for rectangular ductwork. Spiral ductwork is formed by locking metal strips in a spiral fashion into one continuous piece. The spiral pipe is joined together by either sheet metal screws, duct flange, barrel clamps, or spiral pipe connectors.
Spiral duct fittings can help prevent expensive ductwork leakage. They require fewer supports and are the least expensive to seal. Spiral fitting ducts are capable of handling high air velocities with the least friction loss.
Welded Duct Flange
Duct flanges are angle rings constructed from black iron or galvanized steel. These rings can come with or without holes. Flanged ductwork is sealed over round ductwork with a gasket. These flanges can be custom manufactured in a wide range of sizes and gauge thickness. These duct flanges require an expert mechanic who can cut the pieces and weld them properly in order to reduce air leakage.
Clamp Together Ductwork
Clamp together ductwork works similarly to building with Lego blocks. This straight ductwork typically comes in a five-foot length with rolled lips on each end. After the duct is cut, the cut end is placed into a sleeve until both pieces reach the desired length. It’s then simply clamped together. This type of ductwork can be beneficial if you desire to do repair work yourself.
Understanding the various types of oval spiral duct fittings can help you improve the airflow quality in your manufacturing facility. Each type has its own unique advantages and disadvantages.
