US Duct products
Galvanized & Stainless Steel Ductwork
US Duct - Model CTD - Laser-Welded Clamp Together Ducting
Our Laser-Welded Clamp Together Ducting (CTD) uses a gasketed, over-center clamp that seals the rolled lip on the end of ALL clamp-fitting ductwork components. At US Duct we know more about Clamp Together Ductwork than anyone. We provide ALL components and special fittings. The system is infinitely adjustable with adjustment capability built into EVERY fitting. While Clamp Together Duct is often the fastest, easiest and cheapest way to address dust/mist collection, it is often best used in conjunction with other connection methods as dictated by the application, or duct size. Our extensive knowledge will enable you to get the best solution — for the application AND the money.
US Duct - Airtight Quick-Connect Ductwork
We can provide a tighter duct option: US Tubing is a laser welded, airtight duct in a clamp connection style. If you are familiar with popular European tubing products, you`ll understand the value of a truly strong, airtight clamping connection. But because our tubing product is made right here in the USA, there are no overseas shipping delays and you can get even custom products in days — not weeks. The components (pipes, branches, elbows, etc.) are standard 20 gauge metal (galvanized, stainless steel, painted) with a range of 22 to 16 gauge available upon request. The pipe comes in standard 59" lengths which can be easily clamp-connected together to produce long runs. An optional adjustable sleeve pipe allows for field adjustments. US Tubing`s airtight ducting provides the tightness of a flange and gasket seal with the convenience of a clamp together connection system.
US Duct - Flanged Ductwork
US Duct provides duct with flanges (also called angle rings or angle flanges) in black iron, galvanized, or stainless steel (SS) and with or without holes. The duct to which these flanges are attached is available in sizes 3" and up, and also in black iron, galvanized or SS. Construction methods range from laser welded pipe and mechanically lock elbows in lighter gauges to fully welded product in heavy gauge (even up to 1/4")—all depending upon the application.

Galvanized & Stainless Steel Ductwork - Flanged Ductwork
US Duct - Vanstone Flange
This refers to a technique whereby a flange is used to mate 90-degree lips turned onto the pipe or duct component. In this method the flange is placed onto the pipe, the lip turned back and the flange left loose. Typically, the lip is ½” tall (or wide depending on your perspective) when the flanges are pulled together, the VanStoned lips of the pieces that are being connected, are pressed together to make a secure metal to metal connection. Because the flanges are loose on all pieces, alignment of the center-line of the components is easily accomplished. Standard Vanstone pipe lengths are a nominal 59”.
US Duct - Welded Flange
Welded flange refers to flanges that are welded to the duct. The faces of the flanges are the mating surface, as opposed to the Vanstone where the duct lips are mating. Full welded duct flanges have a continuous weld. Intermittently welded duct flanges mean that there is a weld at intervals around the duct. Standard welded flange pipe lengths are a nominal 60”.
