Introduce

Flange is a kind of disc - shaped part, which is the most common in pipeline engineering. Flanges are used in pairs and with the supporting flanges on the valve. In pipeline engineering, flanges are mainly used for pipe connections. In the pipe which needs to be connected, a variety of flange is installed, the low pressure pipe can use the wire flange, and the welding flange is used for more than 4 kilos of pressure. The two flanges are sealed with a seal, then fastened with a bolt. Different pressure flanges have different thickness and use different bolts.

Main role

1. Connect the pipeline and keep the sealing performance of the pipeline.

2. It is easy to replace a certain section of the pipeline.

3, easy to disassemble the inspection of the pipeline situation;

4. It is easy to seal a certain section of the pipeline.
