Precautions for oil leakage in oil pipe joints

Knowledge point: oil pipe interface leakage

Case overview

Recently, a compressor in a petrochemical company leaked oil from the inlet joint of the oil pressure regulating valve oil pipe during operation. We sought maintenance from our company. After inspection, our maintenance engineer reported that the equipment leaked oil during on-site storage and the plug was misappropriated. situation, so it is necessary to install a plug and check the tightening.

This kind of mechanical equipment uses oil as a medium to transmit power and energy. Once this problem is not properly handled, it will not only affect the working performance of the equipment, but also waste resources and cause a certain degree of pollution.

To prevent similar anomalies from recurring, our company recommends:

(1) Misappropriation is prohibited;

(2) If misappropriation is allowed, a warning sign must be hung;

Based on this maintenance record, our engineers analyzed the various causes of oil pipe joint leakage and gave corresponding solutions.

1. Material reasons

If the material of the oil pipe interface is not suitable, it will easily cause rust inside, which will affect the flow of internal liquid or leakage in the interface, causing oil leakage in the oil pipe interface.

Solution: Use stainless steel or oil pipe interfaces made of non-rusting materials.

2. Operational errors

The oil pipe interface may be misaligned during operation, causing the installation to be too tight or too loose, resulting in gaps and oil leakage.

Solution: Reinstall according to the instructions.

3. Product quality issues

The oil pipe interface may have burrs or small gaps during production, causing oil leakage.

Solution: Solve the burrs or chips by cutting and grinding.

4. Different pipe models

The model and format of the oil pipe interface and the related pipes may be unequal, resulting in holes in the interface, resulting in oil leakage.

Solution: Match the relevant oil pipe joints according to the model.

When dealing with oil pipe leakage problems, you should also pay attention to:

1. Safety first: When dealing with oil pipe joint leakage problems, you must pay attention to safety to avoid fire or other dangers.

2. Check other components: If there is oil leakage from the oil pipe joint, it may not only be a problem with the oil pipe joint, but also need to check other components, such as oil pipes, oil pumps, etc., to confirm the safety and reliability of the equipment.

3. Seek professional help: If you encounter an oil pipe joint leakage problem that cannot be solved, it is best to seek help from a professional maintenance engineer.
