Products Description
We are API 5L ERW welded steel pipe Manufacturer, and authorized approval with API 5L certificate,welcome to visit our pipe factory
API 5L Grade B pipe is a common grade pipe for oil and gas pipeline transmissions. It also called L245 Pipe refer ISO 3183,
It is equivalent to material ASTM A106 B or ASTM A53 B, which have similar data on chemical composition, mechanical properties, and applications.
API 5L B covers PSL1, PSL2, Sour Services, for onshore and offshore pipelines.
》PSL1 is generally use,same to ASTM A106 GRB and ASTM A53GR B.
》PSL2 is a higher specificaiton level pipe, has more strict value on chemical and mechanical strenth. More over PSL2 requires more test methods like None Distructive Test, CVN Impact Test, DWT etc. API 5L B PSL2 expressed with API 5L BN/BQ/Q/R/M/N
》Sour Services: For sour pipelines like H2S environment, pipe material have typical resrictions on chemicals element of Carbon, P and S. Referring standard NACE MR0175. API 5L B Pipe for Sour Service expressed in API 5L BNS/QS/MS
Suffix Letter
Suffix letter specified the pipe delivery condition:
R: As rolled
N: Normalizing rolled, Normalized formed, Normalized
Q: Tempered and quenched
M: Thermomechanical rolled or thermomechanical formed
S: Sour Services, comes with PSL2 pipe with for NS, QS, MS, eg API 5L Grade B NS, API 5L B QS
