API 5L Grade B LSAW Steel Pipe – High-Pressure Line Pipe for Oil & Gas
API 5L Grade B steel pipe is a common grade of pipe for oil and gas pipeline transmissions.
API 5L B covers PSL1, PSL2, Sour Services, for onshore and offshore pipelines.
At JSFITTINGS, we combine 40 years of manufacturing and trading experience to deliver line pipes that withstand the harshest environments.
Specializing in Large Diameter LSAW (Longitudinally Submerged Arc Welded) pipes, we bridge the gap between precision manufacturing and global supply chain logistics. Whether you require standard API 5L Gr.B pipes for onshore pipelines or high-spec PSL2 pipes for offshore applications, our four decades of expertise guarantee quality, compliance, and timely delivery.
API 5L Grade B steel pipe is resistant to cracking under sulphide stress, which makes it ideal for sour service.
API 5L Grade. B steel pipe has a long working lifespan, which allows it to be very cost-effective.
Due to easy availability and reasonable pricing, API 5L Grade B Seamless Pipe and welded pipe are the first choice for the Oil and gas industries and is used on a large scale in cross-country pipelines.

FAQ – API 5L LSAW Pipe
Q: What is the difference between API 5L PSL1 and PSL2?
A: PSL1 is a standard quality level for general line pipe applications. PSL2 contains additional requirements for chemical composition (carbon equivalent), notch toughness (impact testing), and stricter non-destructive testing (NDT). We supply both based on your project needs.
Q: Can you provide anti-corrosion coating?
A: Yes. Pipeline longevity is key. We offer in-house coating services including 3LPE (3-Layer Polyethylene), FBE (Fusion Bonded Epoxy), and internal flow efficiency coatings to protect against corrosion.
