PIC-(DIN2527 PN16 Blind flanges)

        Blind flange (blind disk) the formal name of flange cover, there are also called is blind flange.Is the middle flange without hole, for sealed pipe plug.Sealing surface sort is more, in the form of a plane, convex and concave and convex surface, grooved surface, RTJ.Material is carbon steel, stainless steel, alloy steel, PVC and PPR and so on.Blind plate look from the exterior, generally divided into blind plate plate plate, 8 characters/board, board, and ring gasket (flashboard and pad ring are blind pass).

　　Flange cover also called blind flange, flange is an important member of the family.It is mainly a blocking effect, and the nature of the head, tube cap.Appearance is very good, is a piece of steel plate after the car of the front is smooth, hit a circle around the bolt hole, most have a sealing surface.

　　Connection mode: bolt connection this a way.

　　Production process: currently, hebei MengCun County almost all flange cover is made of steel plate directly, use made of the forging process.But met a lot of steel material, such as 20 # steel is qualitative, can only be made of the forging technology of flange cover.

　　Carbon steel A105, 20 #, Q235 material;Stainless steel 304 l, 304 l, 304, 304, 321;Alloy steel F1, F5a, F9, F11, F12, making, F91 and other materials.

　　Sealing surface forms: total plane, surface, concave and convex surface, grooved surface, RTJ.
