API Spec 5L specifies requirements for the manufacture of two
product specification levels (PSL 1 and PSL 2) of seamless steel
pipe and welded steel pipes. This standard covers the steel pipes
made from different manufacturing process like seamless steel
pipe, Electric Resistance Welded (ERW) steel pipe, Longitudinal
Seam Submerged Arc Welding (LSAW) pipe and Spiral Submerged-Arc
welding (SSAW) pipes.
Application of API 5L Grade X*0 LSAW Steel Pipe:
API 5L Grade X*0 LSAW Steel Pipe is used in oil and gas
transportation especially in deep sea where the environment is
complicated and harsh.
Manufacturing Process of API 5L Grade X*0 LSAW Steel Pipe:
API 5L Grade X*0 LSAW Steel Pipe is manufactured by forming the
X*0 steel plates into a round shape then welding the seam through
automatically arc welding process. In the production of API 5L
X*0 LSAW Steel Pipe, plates of grade X*0 are formed by the
molding machine into round shape then welded through double-sided
submerged arc welding.
