Differences Between SSAW, LSAW and ERW Steel Pipe
With 40 years of manufacturing expertise, JSFITTINGS explains the key differences in manufacturing, pressure ratings, and applications of LSAW, SSAW, and ERW pipes to help you choose right.
Grade: API 5L Grade B Steel Pipe
Manufacturing type: Seamless, ERW, LSAW, SSAW
Ends: Plain, Beveled
Coatings: FBE, 3PE/3LPE, Black Painting, Varnished
Uses: For conveying gas, water, and oil either in oil, natural gas, steel structure, power plant, ship building, foundation and piling projects.
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.

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.

With 40 years of manufacturing expertise, JSFITTINGS explains the key differences in manufacturing, pressure ratings, and applications of LSAW, SSAW, and ERW pipes to help you choose right.
Galvanized steel pipes are commonly used in industrial systems, water supply systems, fencing, scaffolding, structural frameworks, HVAC, and construction, offering a durable, cost-effective solution where corrosion is a concern.
By understanding the manufacturing process, standards, and applications of ERW steel pipes, you can save your project from high costs without compromising on quality.
The difference between ASTM A333 steel pipe and ASTM A106 steel pipe is that ASTM A333 is a low-temperature carbon steel pipe that can be used as a structural pipe, while ASTM A106 is a non-structural carbon pipe that is used in high-temperature applications.
