Jan 01, 2017 · Steel tubes are widely used in many industrial applications, and are usually distinguished by their method of production. They can be produced either seamless (with diameter from 21 to 406 mm) or with seam method by longitudinal welding (with diameter from 10 to 1630 mm) or spiral welding (with diameter from 160 to 3000 mm) from rolled strip or thick plate .

SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush. Spiral Welded Pipe - an overview ScienceDirect Topics184.108.40.206.5 Spiral-welded pipe. Spiral-welded pipe is produced from coils of steel that are unwound and flattened. The flattened strip is formed by angled rollers into a cylinder of the desired diameter. Interior and exterior SAW seal the spiral seam. At the end of the coil, a new coil is butt-welded to the trailing edge of the pipe, forming a cross seam.
