ASME B16.5 Custom Flanges Fluid Machining Project

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

Product: Flange
Standard: ASME B16.5
Outer Diameter (OD): 318 mm
Wall Thickness (T.K.): 28 mm
Quantity: 5,430 tons

Throughout this project, we maintained strict quality control at every stage of production — from material selection to final inspection. All flanges were manufactured and tested precisely according to the client’s customised dimensional requirements, ensuring full compliance with ASME B16.5 standards and the client’s specifications.

As these are customised products, we took the initiative to go beyond routine compliance. We actively engaged with our client to understand their specific application environment, including pressure ratings, temperature conditions, and connection compatibility. Based on this understanding, we provided professional recommendations on flange facing, bolt hole alignment, and gasket selection.

This proactive, solution-oriented approach helps our customers avoid potential leakage risks, optimise assembly efficiency, and ensure long-term joint integrity. Our goal is always to create a win‑win partnership — delivering reliable, high‑quality customised products while offering value‑added advice that supports our clients’ project success.

At Hunan Great Steel Pipe Co., Ltd., we are proud to support global industrial and piping projects with precision manufacturing, rigorous quality assurance, and tailored engineering support.
