　　SY/T 5037-91 SSAW steel pipe is also called spiral welded pipe. It is formed by rolling low-carbon structural steel or low-alloy structural steel into tube blanks according to a certain spiral angle (called forming angle), and then welding the tube seams. It can be produced from narrower strip steel. Large diameter steel pipe.
