What is Blind Flange

garlock-flat-face-raised-face-blind-flanges

Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels and then the cover plate will be connected to create the - Blind Flange".

Blind flange could also called blind disk or flange pipe plug what owing to their function way. Actually the blind flange has no holes in the center and for to seal the pipe opening. The difference is blind flange is a detachable equipment, easy to replace or do maintenance.

Alloy Steel Blind Flange application are popular in many field, such as chemical industry and oil&gas project. Alloy Steel Blind Flange is a solid disk used to block off a pipeline or to create a stop what is useful for making repairs to a pipeline and for expansion or continuation of the pipeline simply by adding onto the final flange.

Specification of ASME B16.5 Forged Steel Flanges

ASME B16.5 standard covers pressure temperature ratings, materials, dimensions, tolerances, marking, testing and methods of designating openings for pipe flanges and flanged fittings. Such as weld neck flanges, slip-on flanges, socket weld flanges, threaded flanges, blind flanges, lap joint flanges and flangolets.
