Aug 06, 2011 · 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 Steel Pipe, EFW Steel Pipe, Welded Steel PipesLSAW 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. Features:-Large diameter steel pipes-Thick walls-High-Pressure resistance
LSAW Steel Pipe is a professional term for LSAW steel pipe. LSAW steel pipe is produced from a single medium and heavy plate, which is pressed into a tube blank in a mold or forming machine, and is expanded by double-sided submerged arc welding.
