Flange is an important part of connecting pipelines. Its function is to connect pipelines and equipment to make them airtight and stable. In order to ensure its normal service life and performance, we need to carry out regular maintenance and maintenance on it. Below are some suggestions for maintenance.

1. Regularly clean the flange

During the use of the flange, some dirt and corrosion will accumulate, which will affect its sealing and stability. Therefore, we need to clean it regularly to remove the dirt and corrosion on its surface. A cleaning agent and soft cloth can be used for cleaning, be careful not to scratch the surface with hard objects, so as not to scratch the surface.

2. Check the tightness of the flange

The tightness of the flange is one of its most important properties. If the tightness is not good, it will cause pipeline leakage and equipment damage. Therefore, we need to check its tightness regularly. During the inspection, a pressure gauge or a hydraulic testing machine can be used to perform a pressure test on the flanged pipes and equipment to check for leakage.

3. Apply rust inhibitor

The flange is easily corroded during long-term use, so we need to apply an anti-rust agent to protect its surface. When applying, you can choose an anti-rust agent suitable for its material, apply it evenly, and be careful not to apply too much, so as not to affect its sealing.

4. Regularly replace the flange gasket

The flange gasket is an important part to ensure the sealing of the flange. After long-term use, it will be aged and worn, resulting in a decrease in sealing. Therefore, we need to replace the flange gasket regularly and choose a gasket suitable for the material and specification for replacement.

5. Regularly check the flange bolts

Regularly check the flange bolts. The bolts at the flange connection are also important parts. If the bolts are loose or damaged, the connection will become loose or leak. Therefore, it is necessary to check its bolts regularly to ensure that they are firmly tightened.

In short, maintaining flanges is an important measure to ensure the normal operation of pipelines and equipment. We need to clean, inspect, apply an anti-rust agent, and replace the gasket regularly to ensure its tightness and stability. At the same time, we also need to pay attention to the method of use and installation to avoid damage.
