API 5L seamless steel pipe is a premier standard for conveying oil, gas, and water in the petroleum and natural gas industries. It eliminates the need for welds by piercing and rolling solid billets, creating a uniform, high-strength structure that easily withstands extreme pressure and temperature.
Manufacturing Process: Seamless (Hot-Rolled up to 26″ or Cold-Drawn below 3″).
As a specialized manufacturer, JS FITTINGS supplies API 5L seamless line pipes across all grades, including Grade B, X42, X46, X52, X56, X60, X65, and X70, in both Product Specification Levels (PSL1 and PSL2).

|---|---|---|---|---|---|
| Grade B | 0.28% | 1.20% | 0.030% | 245 MPa | 415 MPa |
| X52 | 0.28% | 1.40% | 0.030% | 360 MPa | 460 MPa |
| X65 | 0.28% | 1.40% | 0.030% | 450 MPa | 535 MPa |
Choosing between PSL1 and PSL2 is critical for project safety:
The backbone for long-distance oil and natural gas transmission lines.
Utilized in risers and seabed pipelines where external pressure is extreme.
Specially treated API 5L pipes resist hydrogen-induced cracking (HIC).

Q: Is API 5L Grade B equivalent to ASTM A106 Grade B?
A: They are similar but not identical. ASTM A106 is for high-temperature service, while API 5L is for line pipes. However, many of our seamless pipes carry dual certification to meet both standards.
Q: Can you provide 3LPE coating for API 5L pipes?
A: Yes. We offer in-house coating services for 3LPE, 3LPP, FBE, and Hot-dip Galvanizing based on your project environment.
Q: Do you support third-party inspection agencies?
A: Absolutely. We regularly work with SGS, BV, and TUV to ensure our products meet the highest international standards before shipment.
