API 5L PSL2 Grade L360NS Seamless Pipe and Fittings for Construction Project

At Hunan Great Steel Pipe Co., Ltd., we are pleased to present one of our recent project applications — the supply of seamless pipe and matching fittings to an international client.

Product: Seamless Pipe and Fittings (SMLS Pipe + Fittings)
Standard: API 5L PSL2
Grade: L360NS (X52)
Outer Diameter (OD): 406.4 mm
Wall Thickness (T.K.): 12.7 mm / 19.05 mm
Quantity: 1,750 tons

Throughout this project, we maintained strict quality control at every stage of production — from material selection to final inspection. All pipes and fittings were manufactured and tested precisely according to the client’s customised dimensional and performance requirements, ensuring full compliance with API 5L PSL2 standards and the client’s specifications.

Given that these are customised products, we went further than routine compliance. We proactively engaged with the client to understand their specific application environment, including operating pressure, temperature fluctuations, and the corrosive nature of the transported medium. Based on this understanding, we provided professional recommendations on wall thickness selection, fitting compatibility, welding procedures, and non-destructive testing (NDT) methods.

This solution-oriented approach helps our clients avoid potential operational failures, optimise system integrity, and reduce life-cycle costs. Our goal is always to create a win‑win partnership — delivering reliable, high‑quality customised products while offering value‑added technical advice that ensures long-term project success.

At Hunan Great Steel Pipe Co., Ltd., we are proud to support global energy and industrial projects with precision manufacturing, rigorous quality assurance, and engineering expertise tailored to each client’s unique needs.
