PVC spiral pipe from Sheet Metal Connectors, Inc. is formed from a coil of metal into a rigid PVC tube with a 4-ply spiral lockseam. It has a smooth interior for 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. Optional corrugations are available which increase the rigidity of the pipe by approximately 300%. Pipe sections can be joined together by an E-Z Flange with Barrel Clamp, E-Z Flange Jr. with Barrel Clamp, or Standard Spiral Pipe Connector.
E-Z Flange Jr. with Barrel Clamp – 6 to 24-inch Diameter
The E-Z Flange Jr. with Barrel Clamp, available in diameters of 6 to 24 inches, is a 5/8” flange turned out 90° on each end of the spiral pipe and fittings. The installer applies a gasket on one flange, mates the two flanges together, and attaches the barrel clamp. For field cuts a 5/8” flanged sleeve is available, cut the spiral pipe to the measured length and apply the sleeve.
