The full name of LSAW steel pipe is spiral seam submerged arc welded pipe, which is often used in urban infrastructure, chemical industry, oil and gas transportation and other fields that need long-distance transportation. LSAW steel pipe is well known in the modern industrial and global steel pipe market for its superior corrosion resistance, high strength and good weldability.
