Definition of 2 INCH 150# RF BLIND FLANGE
It is a flange without a hole in the middle, used to seal pipeline openings. The function of the blind plate seal is the same as that of the head and pipe cap, except that the blind plate seal is a detachable sealing device, and the seal of the head is not intended to be opened again.
Purpose of 2 INCH 150# RF BLIND FLANGE
Blind plates are mainly used to completely isolate the production medium, preventing production from being affected or even causing accidents due to poorly closed shut-off valves. Blind plates should be installed at locations that require isolation, such as equipment connection ports, before and after shut-off valves, or between two flanges. It is often recommended to use an 8-shaped blind plate; Insert plates (circular blind plates) can also be used for pressing, blowing, and other disposable parts.
