The E-Z Flange Spiral Pipe System has factory installed flanges on the ends of the spiral pipe and fittings which adds strength and rigidity to the system. The flanges are attached by either spotwelds or button lock, there are no screws protruding into the air stream. Factory installed E-Z Flanges are sealed internally making an airtight and better looking connection.
The E-Z Flange Spiral Pipe System is assembled by applying a gasket to one flange, mating the two flanges together, and attaching the barrel clamp. The E-Z Flange Spiral Pipe System is sealed so tight that it out performs both ASHRAE and SMACNA Leakage Class 3 Testing. There is virtually no leakage at the transverse connections (test data available).
