Therefore, the requirement on the reliability of the pipeline expansion joint is high.
Bellows expansion joints are typically internal pressure type of operation. 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 is subjected to the pressure of the medium. When the pipeline extends or contracts due to thermal expansion and cold contraction, the corrugated pipe is under the action of stretching or compressing force, and the pressure borne by the inner wall of the corrugated pipe is added, so that in the long-term use process, the expansion amount generated by the heat supply pipeline is large, the wave number of the corrugated pipe is large, the corrugated pipe of the expansion joint is easy to leak due to fatigue, and the whole expansion joint can be failed once the internal pressure type corrugated pipe expansion joint leaks. Therefore, the expansion joint of the pipeline needs to be maintained or replaced regularly, so that the service life of the expansion joint is short, the workload of maintenance and replacement is large, and the cost is high. Sometimes, the leakage and the failure expansion joint can not be found in time, and even the production safety accident is caused.
