Stainless steel flange cover

Stainless steel flange blind
Flange cover features: also known as blind flange and blind plate. It is a flange without hole in the middle, which is used to seal the pipe plug. The function is the same as that of welded head and threaded pipe cap, except that blind flange and threaded pipe cap can be removed at any time, while welded head cannot. There are many types of sealing surfaces, including full plane, convex surface, concave convex surface, tenon groove surface and ring connection surface.
