Blind flanges

Blind flanges are designed to close the ends of pipelines or equipment nozzles and are essential for maintenance, pressure testing, and system isolation. With no bore, they completely shut off fluid flow, making them suitable for high-pressure, high-temperature, or corrosive media in oil & gas gathering systems, chemical plants, boilers, and offshore installations.
Blind flanges solve challenges such as temporary or permanent shutdown, reliable pressure testing, and safe system isolation.

Our Blind flanges offer high structural strength, precise sealing surfaces, and full compliance with GOST, ANSI, or DIN standards. Available in carbon steel, stainless steel, or alloy steel, they provide stable performance for demanding industrial conditions.
