Flange is also called flange plate or flange. Flanges are the parts that connect pipes to each other and are connected to pipe ends. There are holes on the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flanges are threaded (threaded) and welded.

Flange is a kind of disc shaped part, which is common in pipeline engineering. Flanges are used in pairs and with matching flanges on valves. In pipeline engineering, flanges are mainly used for connection of pipelines. For the pipes to be connected, a flange plate shall be installed for each type. Screw flanges can be used for low pressure pipes, and welding flanges can be used for pipes with a pressure of more than 4 kg. Add a gasket between the two flanges and fasten them with bolts.

1. Connect the pipeline and maintain its sealing performance;

2. It is convenient to replace a section of pipeline;

3. It is convenient to disassemble and check the pipeline;

4. It is convenient to close a section of pipeline.
