Octal supply API 5L welded (ERW, EFW, LSAW, SSAW) steel line pipe in Gr B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1, PSL2 and for sour service (NACE pipe).Line pipe brief introduction. API 5L steel line pipe is for oil and gas industries pipelines, developed for different working environments.
The form of sch40 pipe is defined in ASTM A135, and TPMC refers to ASTM A53. 2. The manufacturing method is HFW (high frequency electric resistance welding), and available UOE/JCOE of LSAW
Difference between ERW Pipes, SSAW Pipes and LSAW Pipes Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing.

LSAW pipe is referred to longitudinal submerged arc welded pipe which is made of hot rolled steel plate or coils. LSAW tube always goes to the big-sized diameter welded pipe, which cant be processed by electric resistance welding technology.
Petrosadid:Electric Resistance/ Fusion Welded (ERW and EFW)ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.
Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld or Longitudinally Submerged Arc Welded Steel pipes (LSAW).

In this standard, the pipe Outer Diameter smaller than 12.75 in (NPS 12, DN 300), pipe actual diameters is larger than NPS (Nominal Pipe Size)or DN (Nominal Diameter). On the hand, for steel tube dimensions, the actual outside diameter same with pipe number for all sizes.

LSAW pipes compete with seamless and ERW pipes in the size range between 16 and 24 inches but are must-go options for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).
