Background
The pipeline compensator is generally installed in a heat supply pipeline or a gas transmission pipeline in a segmented mode and used for compensating the telescopic displacement of the pipeline, particularly a long-distance heat supply pipeline for transmitting high-temperature and high-pressure media, the wall thickness of the compensator is large, the strength of the compensator is high, and the axial displacement of the pipeline is absorbed more. Therefore, the reliability requirements for the pipe compensator are high.
At present, most of the common corrugated pipe compensators work in an internal pressure type mode. After the medium is introduced into the pipeline, the medium can enter the inner cavity of the corrugated pipe, namely the inner wall of the corrugated pipe can bear the pressure of the medium. When the pipeline is extended or contracted due to thermal expansion and cold contraction, the corrugated pipe is subjected to the acting force of compression or stretching, and the corrugated pipe is twisted due to uneven stress. Meanwhile, the pipeline can also generate vibration in the operation process, so that stress concentration is formed at the wave crest or the wave trough of the corrugated pipe, the corrugated pipe is easy to leak due to fatigue in the use process, and the whole compensator can fail once the internal pressure type corrugated pipe leaks. Therefore, the pipeline compensator needs to be maintained or replaced regularly, so that the service life of the compensator is short, the workload of maintenance and replacement is large, and the cost is high.
