Introduction:
Spiral steel pipe is a kind of welded steel pipe by spiraling the steel strip or coil under the normal temperature through automatic double wire double-sided submerged arc welding process. It is also called SSAW pipes. Spiral welded pipe is characterized by uniform deformation, small residual stress, no surface scratches during the molding process. The SSAW pipes are mainly used for conveying oil and natural gas pipeline, can also be used for civil engineering structures pipes for docks, bridges and other basic pile.
