Blind flange

Overview:

The official name of a blind plate is Flange cover. Some also call it blind flange or pipe plug. It is a flange without a hole in the middle and is used to seal the pipe opening. The function it serves is the same as that of the head and the pipe cap. However, the blind plate seal is a detachable sealing device, while the seal of the head is not intended to be opened again. There are many types of sealing surfaces, including flat surface, convex surface, concave-convex surface, tenon and groove surface, and ring connection surface.
