High-corrosion-resistant and wear-resistant multi-stage pumps are widely used in industrial fields, but sometimes pipeline ruptures occur during long-term operation. There are many reasons for this, and the following are the main reasons and corresponding solutions.

1. Improper Material Selection

The choice of pipeline material is crucial for its corrosion resistance and wear resistance. If the selected material cannot adapt to the specific medium and environment, the pipeline is easily subject to corrosion and wear, leading to rupture. Therefore, when selecting pipeline materials, factors such as the nature of the medium and the working environment must be considered.

Solution: Select appropriate materials for the specific use environment, such as stainless steel, cast iron, and special alloys. For corrosive media such as strong acids and strong alkalis, materials with excellent corrosion resistance should be selected.

2. Design and Installation Issues

The design and installation quality of the pipeline directly affect its operational safety. Unreasonable design or improper installation may lead to stress concentration and vibration in the pipeline, which in turn can cause rupture.

Solution: Strengthen design review to ensure that the pipeline layout is reasonable and the stress is uniform. During installation, strictly follow the specifications to ensure that the connections between the pipelines are firm and well-sealed.

3. Fatigue and Wear

During operation of the multi-stage pump, due to the high-speed flow and impact of the medium, the pipeline will be subjected to considerable pressure and friction, and long-term operation may lead to pipeline fatigue and wear.

Solution: Regularly inspect and maintain the pipeline, and replace severely worn parts in a timely manner. For critical parts, welding or spraying can be used to increase wear resistance.

4. Pressure and Temperature Effects

Fluctuations in pressure and temperature within the pipeline can also lead to pipeline rupture. Excessive pressure or temperature can reduce the strength of the pipeline material, causing rupture.

Solution: Strengthen the monitoring of pipeline pressure and temperature to ensure that it operates within the allowable range. For high-temperature and high-pressure environments, high-strength and high-temperature-resistant materials should be selected.

Summary: There are various reasons for pipeline rupture in high-corrosion-resistant and wear-resistant multi-stage pumps, including material selection, design and installation, fatigue and wear, and pressure and temperature factors. To ensure the safe operation of the pipeline, these factors must be fully considered, and corresponding preventive measures must be taken.
