API 5L generally refers to the execution standard for pipeline steel pipes. Pipeline steel pipes include seamless steel pipes and welded steel pipes.
Currently, the commonly used welded steel pipe types on oil pipelines include spiral submerged arc welded pipe (SSAW), straight seam submerged arc welded pipe (LSAW), and electric resistance welded pipe (ERW). Seamless steel pipes are generally selected when the pipe diameter is less than 152mm.
The specifications of seamless steel pipe are: Φ21.3-1016mm×2.11-55mm
The specifications of API 5L ERW high-frequency straight seam steel pipe are: 48.3mm-610mm×2.77-15.09mm
API 5L LSAW automatic submerged arc welding straight seam specifications are: 426-1524mm×4.5-52mm

Quality Standard Comparison
1. The quality standard of PSL2 is higher than that of PSL1. These two specification levels not only have different inspection requirements, but also different requirements for chemical composition and mechanical properties. Therefore, when ordering according to API 5L, the terms in the contract must not only indicate specifications, steel grades, etc. In addition to the usual indicators, the product specification level must also be indicated, that is, PSL1 or PSL2. PSL2 is stricter than PSL1 in terms of chemical composition, tensile properties, impact energy, non-destructive testing and other indicators.
2.PSL1 does not require impact performance. For all steel grades of PSL2 except X80 steel grade, full size 0℃ Akv average: longitudinal ≥101J, transverse ≥68J.
