Blind Flanges

Blind Flanges are solid disk-shaped components used to terminate or seal the end of piping systems or pressure vessels. With no opening in the center, these flanges provide a complete closure, making them ideal for high-pressure applications, inspection, or future pipe expansion. At Turnon Alloys, we specialize in delivering high-performance solutions for critical operations across industries.

What exactly are Blind Flanges? They're forged components designed to withstand intense pressure and prevent leaks in pipeline systems. These flanges are bolted onto pipes, valves, or pressure vessel openings and can be easily removed for maintenance or modifications. Blind Flanges play a vital role in ensuring operational safety and flexibility. In countries like the USA and Canada, they are called "Blind Flanges," while in Germany they’re referred to as "Blinde Flansche," and in Japan, "ブラインドフランジ" (Buraindo Furanji).

Blind Flanges offer key advantages. They help isolate pipeline sections without cutting or welding, save maintenance time, and increase overall system safety. Their ability to withstand high pressure and extreme temperatures makes them indispensable in petrochemical, oil & gas, and power generation industries. These flanges are also ideal for pressure testing systems without fluid loss. Turnon Alloys supplies components compliant with ASTM A105 for carbon steel, ASTM A182 for stainless and alloy steel, and ASTM A350 for low-temperature service, ensuring top-notch performance under any conditions.
