Longitudinally Submerged Arc Welding Pipe is subdivided into UOE, RBE, JCOE steel pipe according to its different forming methods. Longitudinal high-frequency welded steel 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.

When compared UOE vs JCOE pipes, LSAW steel pipe manufacturers in China can produce more sizes as:

Outside Diameter:219mm-1625mm;
Wall Thickness: 6.35 mm – 60 mm;
Length: 2 m – 18 m

From this, we can see that the LSAW pipe having superiority. We, Bao Steel offers LSAW pipe with high quality, competitive prices, and best service.
