What is Spiral Piping ?
spiral pipe is formed from a coil of prime metal into a rigid steel 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 or welded pipe.
Single-Wall Spiral Pipe :-
Sheet Metal Connectors, Inc. 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 an E-Z Flange with Barrel Clamp, E-Z Flange Jr. with Barrel Clamp, Standard Spiral Pipe Connector, or Companion Angle Rings.
Pressed Fittings :-
All stamped fittings are manufactured from extra deep drawing steel (EDDS) in accordance with ASTM–A653. This type of steel is manufactured by domestic steel mills and has some unique qualities. Stamped fittings are precision drawn, tolerances must be within + or - .002 thickness to assure a quality product at all times. All material is 22 ga. galvanized with a G90 coating thickness and is chemically treated to retard white rust.
