API 5L GR.B ERW steel pipe covers PSL1, PSL2, Sour Services, for onshore and offshore pipelines. Manufacturing types including ERW, EFW, HFW.
PSL1 is normal line pipe standard, PSL2 is a higher specifically level pipe, has more strict value on chemical and mechanical strength. More over PSL2 requires more test methods like None Destructive Test, CVN Impact Test, DWT etc.
API 5L B PSL2 expressed with API 5L BN/Q/R/M
Sour Services: For sour pipelines like H2S environment, pipe material have typical restrictions on chemicals element of Carbon, P and S. Referring standard NACE MR0175.
