Spiral U

What Is Spiral Pipe?

Spiral pipe 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 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 can be joined together by a Standard Spiral Pipe Connector, Gasketed Spiral Pipe Connector, Flange with Barrel Clamp, or Companion Angle Rings.
