The formal name of blind disk is Flange cover, and some are also called blind flanges or pipe plugs.
It is a flange without a hole in the middle, which is used to plug the pipe opening. The function is the
same as that of the head and cap, except that the blind seal is a removable sealing device, and the
seal of the head is not ready to be opened. There are many types of sealing surfaces, including planar,
convex, concave and convex surfaces, tongue and groove surfaces and ring connection surfaces.
Materials include carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR.
