What's the difference between the flange and the flange cap?
A hollow, a solid. Nothing else.
Flanges, also known as flanges, usually refer to a connecting piece that opens several fixed holes in the periphery for connection. Widely used in machinery, form the shape of all sorts of strange things, as long as the image is called the flange, from English flange. The utility model relates to a medium used for connecting pipe fittings, which is a ring made of material which has plastic deformation and has a certain strength (and now has a non-circular flange connection). Most gaskets are cut from non metal plates or made by professional factories according to the specified sizeFlange cover is also called blind flange and blind plate. It is a flange without holes in the center for sealing the plug of the pipe. With welding head and screw cap is the same, but the blind flange and screw cap can be unloaded, and the welding head. There are many forms of sealing surface, such as flat surface, convex surface, concave convex surface, tenon and groove surface and ring connecting surface.
The biggest difference is that there is a hole in the middle of the flange and there is no hole in the middle of the flange cover
