Product Description

The formal name of blind disk is Flange cover, and some are also called blind flange or pipe plug. It is a flange without a hole in the middle, which is used to block the pipe opening. The function is the same as that of the head and pipe cap, except that the blind plate seal is a removable sealing device, and the head seal is not ready to be opened again. There are many types of sealing surfaces, including FF RF FM  tongue and groove surfaces and ring joint surfaces. Materials include carbon steel, stainless steel, alloy steel, and aluminum.

From the appearance, the blind plate is generally divided into plate type blind plate, spectacle blind plate, plug plate and backing ring (the plug plate and backing ring are mutually blind). The blind plate plays the same role as the head, pipe cap and welding plug in isolating and cutting off. Because of its good sealing performance, it is generally used as a reliable means of isolation for systems requiring complete isolation. Plate plate blind is a solid circle with a handle, which is used for systems in isolation under normal conditions. The shape of the spectacle blind plate is like an spectacle blind plate. One end is a blind plate and the other end is a throttling ring. However, the diameter of the spectacle blind plate is the same as the pipe diameter, and it does not play a throttling role. The spectacle blind plate is easy to use. When isolation is required, the blind plate end shall be used. When normal operation is required, the throttling ring end shall be used. It can also be used to fill the installation gap of the blind plate on the pipeline. Another feature is that the identification is obvious and the installation status is easy to identify.
