HIGH QUALITY WELDED STEEL PIPES
Products Introduction
Welded steel pipes can be divided into ERW, SSAW, and LSAW pipes according to different manufacturing process.
ERW steel pipe is welded by high-frequency current after rolling steel plates into tube shape.
SSAW steel pipe is a type of spiral welded steel pipe made of steel coil as raw material, extruded at room temperature, and welded by automatic submerged arc welding technology.
LSAW steel pipe is one of straight seam welded steel pipes, which has the advantages of excellent pressure resistance performance, high strength, convenient for welding and high dimensional accuracy.
We supply high quality ERW, SSAW, and LSAW pipes. Our steel pipes can meet the requirements of multiple standards, such as ASTM, JIS, EN, API 5L, and GOST, etc. Welcome to you purchase.
