What can replace the 8-character blind plate?

Blind plate is a flange with no hole in the middle, which is used to block the nozzle.

The figure-8 blind plate is a kind of pipe fittings, mainly for the convenience of maintenance. The specific shape can be painted black on the upper part of the figure-8. This is half blind and half hoop.

2. Different roles

The function of blind plate is the same as that of head and pipe cap, except that blind plate seal is a detachable sealing device, and the seal of head is not ready to be opened again. There are many types of sealing surfaces, including plane, convex surface, concave-convex surface, tenon-groove surface and ring connection surface. Materials are carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR.

8-shaped blind plates are often used for pipeline flanges that need to change the process. The main materials are carbon steel, stainless steel and alloy, which can be selected according to the pipeline pressure grade and pipeline medium.

3. Different characteristics

The blind plate is mainly used to completely isolate the production medium, so as to prevent the production from being affected or even accidents caused by the lax closing of the cut-off valve. Blind plates should be set in the parts that need isolation, such as the nozzle of equipment, the front and rear of cut-off valve or between two flanges. It is usually recommended to use 8-shaped blind plates. Inserts (circular blind plates) can also be used for disposable parts, such as suppression and purging.

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.
