API 5L PSL2 Grade X52 Seamless Steel Pipe Energy Project Transport

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

Product: Seamless Steel Pipe
Standard: API 5L PSL2
Grade: X52
Outer Diameter (OD): 18 inches (457.2 mm)
Wall Thickness (T.K.): 22 mm
Quantity: 8,450 tons

Throughout this project, we maintained strict quality control at every stage of production — from material selection, hot rolling, and heat treatment to final inspection. All seamless pipes were manufactured and tested precisely according to the client’s customised dimensional and mechanical property 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 nature of the transported medium. Based on this understanding, we provided professional recommendations on wall thickness optimisation, non-destructive testing (NDT) methods, and end finishing options.

This solution-oriented approach helps our clients avoid potential operational failures, enhance pipeline safety, 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 oil, gas, and energy projects with precision manufacturing, rigorous quality assurance, and engineering expertise tailored to each client’s unique needs.
