Product Overview

YUHONG’s Stainless Steel Stationary Flange (ASTM/ASME A/SA182 F310, B16.5 & Custom Made) is designed for high-temperature, high-pressure, and corrosive environments in:

  • Pressure vessels

  • Heat exchangers & reactors

  • Petrochemical & power plants

  • Offshore oil & gas platforms

These flanges are precision-machined, fully tested, and compliant with international standards, ensuring long-term durability and leak-proof performance.


Key Features & Benefits

Premium Material: SA182 F310 (25Cr-20Ni) stainless steel – excellent oxidation & corrosion resistance at high temps (up to 1150°C / 2100°F).
Multiple Standards: Compliant with ASME B16.5, B16.47, or custom designs.
Heat Treatment: Solution-annealed for maximum strength & ductility.
Strict QC: 100% PT (Liquid Penetrant) & RT (Radiographic Testing) inspected.
Customization: Available in RF (Raised Face), FF (Flat Face), RTJ (Ring-Type Joint).
Corrosion Resistance: Ideal for acidic, alkaline, and high-sulfur environments.

Fully meets the rigorous requirements of TEMA R standards. We used these SA266 Grade 2N flanges for a refinery project in Texas. The machining precision is impressive, and the sealing face finish is absolutely perfect.

We were looking for a reliable supplier for offshore platforms, and the quality of these tube side flanges exceeded expectations. The forging flow lines of the SA266 Gr.2N are very intact.
