API 5L welded steel pipes are divided into different grades according to the yield strength grade, such as X42, X46, X52, X56, X60, X65, X70, etc.
These grades represent the yield strength of the steel pipe, which is its ability to resist deformation when subjected to external forces. API 5L welded steel pipe has good corrosion resistance, high strength and good weldability, and can meet the transportation requirements in harsh environments.

Welded Type: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe
For API 5L welded pipe common types as Follows:
ERW: Electric Resistance Welded, for pipe diameter normally under 24 inch.
DSAW/SAW: Double Submerged Arc Welding / Submerged Arc Welding, a substitute welding method than ERW for larger diameter pipes.
LSAW: Longitudinal SAW, for diameter up to 48 inch. Also called JCOE manufacturing process.
