E-Z Flange Spiral Pipe System (Ductwork for HVAC systems)
Sheet Metal Connectors, Inc. E-Z Flange spiral pipe and fittings are one part of our complete line of HVAC products. The spiral pipe is formed from a coil of metal into a rigid tube with a 4-ply lockseam. It has a smooth interior low friction loss with the grooved seam entirely on the outside. This pipe has a resistance to crushing approximately 2 1/2 times that of longitudinal lockseam or welded pipe. Optional corrugations are available which increase the rigidity of the pipe by approximately 300%. Pipe sections are joined together by an E-Z Flange Jr. or an E-Z Flange with barrel clamp, which exceeds ASHRAE and SMACNA Class 3 Leakage Tests.
