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.
Sheet Metal Connectors, Inc. E-Z Flange Spiral Pipe System has a complete line of compatible fittings. E-Z Flange fittings are manufactured on our state of the art fabrication equipment. Many different materials, gauges, and configurations are available. E-Z Flange fittings can be fabricated with standing seam, elbow lock seam, or welded seam construction. Please consult our factory for more information.
All fittings are manufactured with:
• E-Z Flange Jr. with Barrel Clamp – 6″ to 24″ Diameter
• E-Z Flange with Barrel Clamp – 26″ to 96″ Diameter
These forms can also be found in the back of the E-Z Flange Spiral Pipe System Catalog.
