Blind FLANGE

Blind flanges seal unused pipeline ends or valves during maintenance. These blind flanges (ASME B16.5) feature bolt-hole alignment for easy installation. With PTFE linings, blind flanges handle acids and solvents.

Available in carbon/stainless steel, blind flanges support pressure testing up to 1.5x rated capacity. Thick blind flanges (PN100+) prevent deformation in high-torque systems. Custom blind flange diameters (≤DN2500) are machined on demand.

Blind Flange

A blind flange is a type of flange without a hole in the center, which is designed to seal off the end of a pipeline or used to remove debris from a pipeline during maintenance. It is usually made of high quality steel, such as carbon steel, alloy steel or stainless steel, to meet the needs of different working environments.
