How to properly install flanges

The flange is a connecting part between the shaft and the shaft, used for the connection between the ends of the pipe.

In order to prevent corrosion and leakage after flange installation, we should pay attention to a few points:

1, before flange installation, to check the flange surface, whether it is smooth and whether there is rust. The presence of rust is an important cause of flange corrosion.

2, the installation should pay attention to check whether the gasket anti-aging, oil resistance, mechanical properties and flexibility, before installation, pay attention to the surface shape, the shape of the connection is placed correctly.

3, the flange fastening force should be uniform, the cushion compression should be controlled at 1 / 3 or so.
