API 5L Standard Scope
API 5L is the standard specification for the samless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. It includes the requirements for the manufacture of two product specification level (PSL1 and PSL2) API 5L is not applicable to cast pipe.

Product Specification Level PSL1 and PSL2
PSL is the abbreviation of product specification level. The product specification level can be divided into PSL1 and PSL2, it also could be deemed as quality level.
PSL1 for common quality leves where PSL2 is more strictly on chemical composition (CEQ), mechanical properties, nondestructive testing requirement and other test requirements and values.
