LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.
LSAW pipe used to convey low pressure liquid or high pressure petroleum or natural gas, and can be also used widely in structural supports or foundation. The advantage for LSAW type is they could produce more thick wall thickness of pipes, maximum to 120mm.
