Product Introduction

Blind flange is called blind flange for short, but also called solid flange. The middle of the blind flange is solid, and there are bolt holes around it. It looks like an iron cover, so it is also called a flange cover. It is used to seal the end of the pipe. It is generally used at the end of the water supply branch pipe. In addition, it is used to temporarily seal the temporary part of the pipe section when the first pressure test is required. The shape and function of blind flange and spectacle blind are different.

The blind flange can be flat or convex, concave and convex, tenon and groove, and ring connection. It does not have a neck like the neck flange（weld neck flange or hubbed slip on flange）. In short, the blind flange is designed to block the pipe mouth, so that the material in the pipe will not overflow, and is generally used at the end of the water supply branch pipe. There are many types of flange sealing surface, including plane, convex, concave and convex, tenon and groove, and ring connection surface.

Because most flanges allow air or fluid to pass through the internal opening when connecting, and when the blind plate is installed at the end, it can provide a well-formed termination point for the pipe connection, or it can redirect the required medium to another part of the pipe assembly.
Generally, blind flange will be selected under these circumstances and when the pipeline needs to be modified in the future.

Main Function

1. Connect the pipeline and maintain its sealing performance;
2. Facilitate the replacement of a section of pipeline;
3. Easy to disassemble and check the pipeline condition;
4. Facilitate the closure of a section of pipeline.
