Reasons and Solutions for Leakage of oil supply pipe flange joints

Oil supply pipe flange joints are currently used more frequently in various projects and have a wider range of use. Oil leakage will inevitably occur during this level of use. As long as the cause of the oil leakage is found and the Quickly solving the reasons can reduce losses. Let me briefly introduce the various reasons and solutions for leakage of oil supply pipe flange joints.

1. Material reasons

If the material of the oil supply pipe flange joint is not suitable, it is easy to cause rust inside, which will affect the flow of internal liquid or the interface will leak, resulting in oil leakage from the oil pipe interface. The main solution is to replace the oil pipe interface with stainless steel or a material that is not easy to rust.

2. Operation error

The oil supply pipe flange joint may be installed wrongly due to operation, or the installation may be too tight or too loose. Doing so may cause it to chip and leak oil. The best solution is to re-install according to the instructions.

3.Quality of oil supply pipe flange joints

Oil supply pipe flange joints may be made with burrs or small gaps, which can cause them to leak oil. The best solution is to fix the burrs or gaps by cutting.

The oil supply pipe flange joint may be combined with a different pipe type, resulting in a leak in its interface. The best solution is to match the relevant oil supply pipe flange joints according to the model.

4. Working environment of oil supply pipe flange joints

The oil supply pipe flange joint that has been working at high temperature for a long time, due to the creep relaxation of the sealing gasket and the bolt, the residual stress on the gasket is gradually reduced, and the sealing reliability of the oil supply pipe flange joint is gradually reduced. Eventually lead to leak failure. To solve the sealing problem of flange joints, high temperature sealant can be used for sealing. It is suitable for working conditions that require high temperature and pressure conditions for smooth and flat sealing surfaces (butt joints).

5.How to deal with local leakage of oil supply pipe flange joints?

(1) First, check the leakage site and conduct segmental plugging.

(2) Under normal circumstances, at the leakage site, due to the small flange connection gap, it is impossible to inject sealant through the gap to eliminate leakage. Therefore, the flange sealing construction method should be based on the site survey of the leakage site.

(3) In order to achieve effective plugging, before dealing with the local leakage of the oil supply pipe flange joint, the obstacles on the edge of the leakage point in the flange should be removed first, and then the leakage point should be contained by a fixed fixture to form a sealing cavity, and the sealant should be injected, thereby eliminating leakage.

Through the above introduction, I believe that everyone has a certain understanding of the main reasons for the oil leakage of the oil supply pipe flange joints. At the same time, there will be corresponding solutions when the above problems are found, so as to avoid being at a loss when such a situation occurs, which will cause greater damage.
