Flange

Description:

    Flanges are generally used when there is a connection to valves, in-line instruments and/or connection to equipment nozzles is required. A blind flange is a plate for covering or closing the end of a pipe.Flange fittings generally involve pressing two surfaces to be joined tightly together, by means of threaded bolts, wedges, clamps, or other means of applying high compressive forces.Often, a gasket, packing, or an O-ring is installed between the flanges to prevent leakage, but it is sometimes possible to use only a special grease, or nothing at all, if the mating surfaces are precisely formed.
