Large Diameter LSAW Pipe JCOE / UOE for Structural / Piling Applications

Large Diameter LSAW Pipe (JCOE / UOE) for Structural and Piling Applications

Specifications

LSAW (Longitudinal submerge arc welding) 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.
