Spiral Welded Pipe Introduction

Spiral Welded Pipe is In strip steel coil plate for raw materials.Frequent warm extrusion molding, automatic double wire welding double-sided submerged arc welding technology with the spiral seam welded steel pipe.

Is to put the low carbon carbon structural steel and low alloy structural steel strip according to certain helix Angle (called forming Angle) rolled into a tube blank, and then welded pipe joints made up, it can use a narrow strip in the production of large diameter steel pipe.Spiral welded pipe is mainly used in oil, natural gas pipeline, its specification in diameter * wall thickness. Spiral welded pipe with one-side welding and double welding, tube welding shall ensure that the water pressure test, the tensile strength and bending properties of the weld in accordance with regulations.
