API 5L PSL2 Grade X52 Line Pipe for Oil Transport Industrial Project

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

Product: Line Pipe
Standard: API 5L PSL2
Grade: X52
Outer Diameter (OD): 16 inches & 20 inches
Wall Thickness (T.K.): 9.53 mm / 16.66 mm
Quantity: 3,800 tons

Throughout this project, we maintained strict quality control at every stage of production — from material selection, pipe forming, and heat treatment to final inspection and non‑destructive testing. All line pipes were manufactured and tested in accordance with 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, soil conditions, transportation media characteristics, and anticipated temperature ranges. Based on this understanding, we provided professional recommendations on wall thickness optimisation, end finishing options, and anti‑corrosion coating solutions.

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

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