Enpro offers API 5L pipe from API 5L Gr B to X80, product specification level PSL1 and PSL2, used for Onshore/Offshore and sour services (H2S corrosive environment). Manufacturing type including seamless, ERW (Electric resistance welded), SAW (Submerged Arc Welded).
Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe. Owing to the flux layer, there is no instant heat loss and it gets concentrated near the weld.
API 5L specification covers the manufacturing types in welded and seamless. And welded pipe common types are spiral submerged arc welded pipe (SSAW), straight seam submerged arc welding pipe(LSAW), and resistance welded pipe (ERW). Check here for the differences between the ERW, LSAW, and SSAW pipe.
Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from contamination of impurities in the air.
Spiral Welded Steel Pipe API 5L standard ASTM standard SSAW Steel Pipe . SSAW spiral submerged arc welded pipe, submerged arc welding (including submerged arc welding and electroslag welding etc.) is a kind of important welding method, its inherent stable welding quality, high welding productivity, no arc and smoke rarely etc., make it become the pressure vessel and pipe manufacturing, box beam of steel structure in the production of the main welding method.

Welded Pipe manufacturing types There are 3 welding types: ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding) SSAW (Spirally Submerged Arc Welding) welding types. ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe in two different manners as listed below.
ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the use of a pipeline in the transportation of petroleum and natural gas. For material use in a sour service application, refer to Annex H; for offshore service application, refer to Annex J of API 5L 45th Edition.
