Spiral PipeSheet Metal Connectors, Inc. located in Minneapolis, Minnesota and Rockford, Illinois manufactures spiral pipe which is formed from a coil of metal into a rigid steel tube with a 4-ply spiral lockseam. It has smooth interior for low friction loss with the grooved seam entirely on the outside. This Spiral 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 Spiral Pipe by approximately 300%. Spiral Pipe sections can be joined together by an E-Z Flange with Barrel Clamp, E-Z Flange Jr. with Barrel Clamp, Standard Spiral Pipe Connector, or Companion Angle Rings.
