ASTM A312 TP316L Stainless Steel EFW Pipe Construction Project

At Hunan Great Steel Pipe Co., Ltd., we are pleased to present one of our recent project applications — the supply of stainless steel EFW (Electric Fusion Welded) pipes to an international client.

Product: Stainless Steel EFW Pipe
Standard: ASTM A312
Grade: TP316L
Outer Diameter (OD): 20″, 24″
Wall Thickness (SCH): SCH10S
Quantity: 1,350 tons

Throughout this project, we maintained strict quality control at every stage of production — from raw material selection and plate rolling to EFW welding, heat treatment, and final non‑destructive testing. All pipes were manufactured and inspected precisely according to the client’s customised dimensional and wall thickness requirements, ensuring full compliance with ASTM A312 and the client’s specific tolerances.

As this was a customised product, we took extra initiative to understand the client’s actual operating environment, including working temperature, pressure levels, and the corrosive nature of the conveyed media. Based on this understanding, we provided professional recommendations on weld joint design, post‑weld heat treatment parameters, and surface finishing options. This collaborative approach helped the client achieve optimal performance while avoiding potential service failures.

Our goal is always to create a win‑win partnership — delivering reliable, high‑quality stainless steel pipes while offering value‑added, application‑driven advice that protects our clients’ long‑term operational interests.

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