Spiral welded pipe is a low carbon structural steel or a low alloy structural steel strip rolled into a tube blank with a certain helix angle (also called forming angle), and then welded and made into a pipe joint, which can use a narrow strip steel Production of large diameter steel pipes.
The strength of the spiral welded pipe is generally higher than that of the straight welded pipe. The main production process is submerged arc welding. The spiral welded pipe can produce welded pipes with different pipe diameters with the same width of blanks, and can also produce welded pipes with larger diameters with narrow blanks.
