Precautions for oil leakage at the oil pipe joint

Knowledge point: Oil leakage from the oil pipe interface

Case Overview

Recently, oil leaked from the inlet joint of the oil pressure regulating valve oil pipe of a petrochemical company during operation. We sought repairs from our company. After inspection, our maintenance engineer reported that the plug was misappropriated at the oil leakage position during the on-site storage of the equipment, so the plug needs to be installed and checked and tightened.

Once this mechanical equipment that uses oil as the 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 exceptions from reappearing, 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 leakage at the oil pipe joint and provided corresponding solutions.

1. Material reasons

If the material of the oil pipe interface is not suitable, it can easily lead to rust inside, which will affect the flow of internal liquid or leakage of the interface, resulting in oil leakage on the oil pipe interface.

Solution: Use stainless steel or oil pipe interfaces that are not easily rusted.

2. Operation errors

During installation, the oil pipe interface may cause a wrong opening during operation, causing the installation to be too tight or too loose, which will cause the oil leakage from the gap.

Solution: Reinstall according to the instructions for use.

3. Product quality issues

The oil pipe interface may have burrs or small notches during production, resulting in oil leakage.

Solution: Solve its burrs or notches by cutting and sanding.

4. Different pipe models

The model specifications of the pipes in which the oil pipe interface is combined with its related pipe may cause loopholes in the interface due to unequalities, resulting in oil leakage.

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

Pay attention to when dealing with oil leakage in oil pipes:

1. Safety first: When dealing with oil leakage at the oil pipe joint, be sure to pay attention to safety to avoid fire or other dangers.

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

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