Stainless Steel Blind Flange is a specialized piping component designed to seal and close the end of pipes, valves, or equipment nozzles. Fabricated from high-grade 304/316L stainless steel, it delivers superior resistance to corrosion, oxidation, and chemical erosion, making it suitable for harsh industrial environments such as chemical processing plants, oil refineries, marine engineering, and water treatment facilities.
Its core advantage lies in robust sealing performance and structural integrity. The solid disc design provides full-face coverage for leak-proof closure, effectively preventing media leakage and protecting internal piping systems from external contaminants. With excellent pressure-bearing capacity (up to Class 2500), it maintains stability in high-pressure and high-temperature operating conditions. Additionally, the simple structure enables easy installation and removal, facilitating piping maintenance and inspection.
All our Stainless Steel Blind Flanges comply with international standards including ASME B16.5, DIN 2502, and JIS B2220, ensuring precise dimensional tolerances and perfect compatibility with standard piping components. We offer a comprehensive range of sizes (1/2" to 60") and pressure classes to meet diverse project requirements. Each flange undergoes strict quality inspections, including material composition analysis and pressure testing, to guarantee reliable performance and long service life.
