Blind flanges are parts of piping systems considered to be of the best quality stainless steel, which are necessary to close or seal the piping system. We are one of the reliable manufacturers of stainless steel blind flangles in India and provide the customers with the high-quality flanges which guarantee a high level of strength, leakage-free, and durability. Our stainless steel blind flanges are produced through high-technology and high-grade SS steel like SS 304 stainless steel, SS 316 stainless steel, SS 321 stainless steel, and other type of steel as customized to suit our application requirements.
They find application in the oil and gas, petrochemical, power generation, water treatment, pharmaceutical and food process industries. The our blind flanges are designed to operate at high pressure and high-temperature applications, with several pressure classes, such as Class 150, Class 300, Class 600, and Class 900, and others. We adhere strictly to the international standard including ANSI, ASME, DIN and ASTM to comply with the global quality requirements.
