The blind plate is a solid flange, which is used to close the end of the pipe, and is generally used at the end of the water supply branch pipe. There is also a temporary part of the pipe section to be used for temporary closure when the pressure test is performed first. Flange is a disc-shaped part, which is the most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, flanges are mainly used for pipeline connection. In the pipelines that need to be connected, a flange plate is installed for various installations. The low-pressure pipeline can use the wire connection flange, and the welding flange is used for the pressure above 4 kg. A sealing point is added between the two flanges of the flange blind plate, and then tightened with bolts. Flanges with different pressures have different thicknesses and use different bolts.
The true meaning of using flange connection is to have a good sealing connection, which can very effectively protect the smoothness and sealing of the entire pipeline. The effect of large-scale flange connection is also the same, not only can strengthen the efficient sealing effect, but also can be disassembled for secondary use and cleaning. Of course, flanges are not universal products, they are also divided into pressure levels. They must be matched in different pressure pipes or container equipment, and the materials and connected pipes must also be matched with each other. But no matter in any place or project, the flange is also one of the necessary pipe fittings, which play an unusual role in different environments. This is the function and principle of the flange sheet. /uploads/fl/1-1.jpg
