Welded Pipe

Our welded pipes use ERW (electric resistance welding) for carbon steel (wall thickness 2-16mm) and SSAW (submerged arc welding) for stainless steel (3-25mm). Carbon steel pipes meet API 5L standards for low-pressure systems; stainless steel pipes comply with ASTM A312 for corrosive environments. NDT testing (UT/RT) and coating options (FBE/PE) ensure durability. Applications: urban water supply, industrial ducts, and building frameworks.
