What is DSAW Pipe?

DSAW pipe is short for double submerged arc welded pipe, which is available in straight and spiral welded formats and utilized in a variety of applications. The submerged arc welding process protects the steel from contamination of impurities in the air. The inside and outside welds are performed. DSAW steel pipe can be processed in large diameter and to exact inside or outside dimensions.
