Background technique
Pipeline compensator is also expansion joint, and segmentation is installed in heat supply pipeline or gas pipeline, for compensating stretching for pipeline
Contracting, especially for conveying the long range heat supply pipeline of high temperature, high-pressure medium, the wall thickness of expansion joint is larger, intensity is higher, absorbs
The axial displacement of pipeline is more.Therefore higher for the reliability requirement of expansion joint for pipeline.
At present, it is common to use bellows expansion joint be inner pressed working method mostly.After being passed through medium in pipeline, medium
It can enter in the inner cavity of bellows, i.e. pressure of the inner wall of bellows by medium.Pipeline is extended or is received because expanding with heat and contract with cold
When contracting, the active force that bellows is stretched or compresses, in addition the pressure that ripple inside pipe wall is born, in long-term use process, by
Larger in the stroke that heat supply pipeline generates, the wave number of bellows is more, and the bellows of expansion joint is easy to leak because of fatigue,
Inner pressed bellows expansion joint, which once leaks, can make entire expansion joint fail.Therefore periodic maintenance or replacement pipe expansion are needed
Section, causes the service life of expansion joint shorter, the heavy workload of maintenance and replacement, higher cost.Sometimes because failing to find in time
The expansion joint of leakage and failure, even initiation work safety accident, cause serious personal injury and economic loss.
