Description

TECHNICAL FIELD

[0002] At present, the high-pressure pipeline used by the compressed air energy storage system is generally composed of a steel pipe and an inner liner pipe arranged in the steel pipe, and the material of the inner liner pipe is often epoxy resin. In the operation process of the compressed air energy storage system, the inner wall of the high-pressure pipeline will inevitably be worn, and the local wall of the inner liner pipe will be thinned. When the cracks on the inner liner pipe penetrate the inner liner pipe, the gas in the high-pressure pipeline will contact the outer steel pipe, which will cause corrosion of the steel pipe and even lead to leakage of the high-pressure pipeline. Especially at the turning part of the high-pressure pipeline, the wear of the inner wall of the inner liner pipe is more prominent. The traditional repair method is to form a new repair coating on the inner wall of the inner liner pipe by spraying, but the impact force of the gas at the turning part of the high-pressure pipeline is greater than that at the straight pipe part, which is also the reason why the wear of the inner wall of the turning part of the pipeline is more serious. Only the spraying repair method cannot meet the anti-wear requirements of the turning part of the pipeline. SUMMARY
