Spiral tube called the spiral pipe or spiral welded pipe, the low carbon structural steel and low alloy structural steel strip by certain helix angle ( called forming angle ) rolled into a tube, and the pipe joint welding material, it can use a narrow strip production of large diameter steel pipe. Spiral pipe is mainly used in oil, natural gas pipelines, the specification of wall thickness of said outer diameter *. Spiral tube having one side welding and double welding, pipe should ensure that the hydraulic pressure test, the tensile strength of the welding seam and the cold bending property shall comply with the provisions of.
