Description

API 5L Gr.B LSAW Steel pipe Oil Gas Line Pipe


  LSAW steel pipe are steel pipes whose welds are parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on. Longitudinal welded pipe has simple production process, high production efficiency, low cost and rapid development.

       The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. A narrower blank can be used to produce welded pipes with larger pipe diameters, and a billet with the same width can also be used to produce welded pipes with different pipe diameters. However, compared with the straight seam pipe of the same length, the weld length is increased by 30-100%, and the production speed is lower.

      LSAW (Longitudinal double 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.

   LSAW pipes are produced by molding steel sheets to a cylinder and joining the ends together by welding in a straight line.The LSAW pipe diameter range is normally from 16inch to 60inch (406mm to 1500mm). They have good performances on high pressure resistance, and low-temperature corrosion resistance.
