LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional term for longitudinally submerged arc welding. LSAW steel pipe is made of single medium and thick plate as raw material. The steel plate is pressed (rolled) into tube blank in the mold or forming machine, and it is made by double-sided submerged arc welding and expanded diameter. The product has a wide range of specifications, good toughness, plasticity, uniformity and density of the weld, and has the advantages of large pipe diameter, pipe wall thickness, high pressure resistance, low temperature resistance and corrosion resistance. In the construction of high strength and high quality long distance oil and gas pipelines, most of the steel pipes needed are large diameter thick wall straight seam submerged arc welded pipes

Stainless steel pipe is a kind of hollow long circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipeline and mechanical structure parts. In addition, in bending, torsional strength is the same, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for furniture kitchenware.

ERW Steel Pipe, ERW Casing, ERW Carbon Steel Pipe, MS ERW Pipe, GI ERW Pipe, Stainless ERW Pipe

SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush.
