2021年3月26日 · The EN 1092-1 Type 05 flange shall be provided as blind flange, which is used to blank off the piping. Substantially, it is a round solid disc with bolting holes drilled along the circumference. The EN 1092-1 Type 05 blind flanges may be furnished with flat facing (FF) or raised facing (RF).

Blind flanges, just like standard pipe flanges, can be raised face (RF) or flat faced (FF). If the flange is RF we would recommend a standard ring gasket that is appropriate for the service and/or test.
