API 5L Grade B steel pipe is a common grade pipe for oil and gas pipeline transportation. It is also known as L245 pipe, referenced to ISO 3183, named after a minimum yield strength of 245 Mpa (355,000 Psi).Equivalent material ASTM A106 B or ASTM A53 B with similar value in chemical composition, mechanical properties and application.API 5L B covers PSL1, PSL2, sour service for onshore and offshore pipelines.
Usually PSL1 is used, which is equivalent to ASTM A106 B and A53 B.
PSL2 is a higher specification grade pipe with stricter requirements for chemical and mechanical strength. PSL2 requires more test methods such as non-destructive testing, CVN impact testing, DWT, etc.
API 5L Grade B, ASTM A106 Grade B and A53 Grade B, these three materials are the most commonly used materials in pipeline construction or oil and gas and liquid transportation industries.
