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.
