Introduction of submerged arc welded steel pipe

Submerged arc welding steel pipe: it is a spiral seam steel pipe made of strip steel coil as raw material, extruded at room temperature and welded by automatic double-wire double-sided submerged arc welding process. Submerged arc welded steel pipes are characterized by simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. Welded pipes with larger diameters can be produced from narrow blanks, and welded pipes with different diameters can also be produced from blanks with the same width.
