Pipeline r, , r, : , in these projects the pipelines are affected by the settlement of the building foundation, equipment resonance, geological changes, pipeline During the process of medium change, the distribution position of the pipeline begins to receive stress, deformation, distortion and damage to the pipeline. The embedded pipeline or even rupture brings great inconvenience to the construction unit. In order to overcome these difficulties and ensure the safe operation of the pipeline, use telescopic devices,
Expansion joint r, , r, :: It can expand and contract axially within a certain range to overcome various angular displacement, non-concentricity, expansion and contraction of the pipeline. The pipe can be freely expanded and contracted in the expander. Once the maximum expansion and contraction is exceeded, it will act as a limiter. This ensures safe operation of the pipeline!
