Stainless Steel Blind Flange ASTM A182 F304/F316 ANSI B16.5 Class 150 with Raised Face (RF) Forged Construction

Our stainless steel blind flanges are precision-forged from premium ASTM A182 F304 and F316 materials, engineered to provide a reliable seal for the termination of piping systems. Designed in accordance with ANSI B16.5 Class 150 standards with a raised face (RF) configuration, these blind flanges deliver exceptional corrosion resistance and mechanical strength for demanding industrial applications including petrochemical, oil and gas, water treatment, and food processing facilities.

• Premium Material: Manufactured from ASTM A182 F304/F304L and F316/F316L stainless steel for superior corrosion and oxidation resistance in aggressive environments
• Precision Forging: Hot-forged construction ensures uniform grain structure, eliminating porosity and delivering superior mechanical properties compared to cast alternatives
• ANSI B16.5 Compliance: Dimensional accuracy guaranteed through strict adherence to ANSI B16.5, ASME B16.47, and international flange standards
• Raised Face Design: RF surface finish (125-250 AARH) ensures optimal gasket sealing for leak-free performance at rated pressure levels
• Full Traceability: Each flange is heat-number stamped with complete material test certificates (MTC) per EN 10204 3.1 available upon request

We offer comprehensive OEM and brand customization services to meet your specific project requirements. Our flexible manufacturing lines support custom sizes beyond standard dimensions, non-standard pressure ratings, and specialized face configurations. Custom branding options include laser-etched logos, branded plywood case packaging with your company artwork, and customized labeling with your part numbering system. We work closely with engineering teams to develop bespoke flange solutions for unique applications.
