What is a blind plate? What is a blind plate?

1. A blind plate is a flange with no hole in the middle to block the nozzle. The official name of the blind plate is flange cover, which has the same function as the head and pipe cap, but the blind plate seal is a detachable sealing device, and the head is not detachable. There are many kinds of sealing surfaces, such as plane, convex surface, concave-convex surface, tenon-groove surface and ring connection surface. Materials include carbon steel, stainless steel, alloy steel, copper, aluminum, PVC, PPR, etc.

2. From the appearance, the blind plate can be divided into plate-type flat blind plate, figure-eight blind plate, insert plate and cushion ring. Blind plate plays the role of isolation and cutting off, which is the same as that of head, pipe cap and welding plug. Because of its good sealing performance, it is generally used as a reliable isolation means for systems that need complete isolation. Plate blind plate is a solid circle with handle, which is normally used for isolation system. The splayed blind plate is splayed, one end is a blind plate, and the other end is a throttling ring, but the diameter is the same as the pipe diameter, so it has no throttling effect. The figure 8 blind plate is easy to use. Use blind plate end when isolation is needed, and use throttle ring end when normal operation is needed. It can also be used to fill the installation gap of the blind plate on the pipeline. Another feature is that the logo is obvious and it is easy to identify the installation state.
