What is LSAW steel pipe definition?
LSAW means Longitudinal Submerge Arc Welding carbon steel pipe. It is a kind of SAW pipe made of steel plates that were hot rolled by JCOE or UOE manufacturing process. JCOE technology means the shaping and forming processes. This forming process JCOE include during producing as well as the inner and outer welding and cold expansion carried out after welding. When compared UOE vs JCOE pipes, LSAW steel pipe manufacturers in China can produce more sizes as: Pipe Outside Diameter: 406mm - 1524mm;
UOE (Uing and Oing forming) LSAW Steel Pipes UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expander to improve dimensional accuracy, and eliminate residual stress
