LSAW Pipe is subdivided into UOE, RBE, JCOE steel pipe according to its different forming methods.
LSAW Pipe has the characteristics of relatively simple process and fast continuous production, and has wide use in civil construction,petrochemical, light industry and other sectors.
Mostly used to transport low-pressure fluids or made into various engineering components and light industrial products.
