Engineering pipelines are subject to building foundation settlement, equipment resonance, geological changes, pipeline medium changes in the process, the location of the pipeline distribution began to stress, deformation, distortion damage pipeline, pre-buried pipeline and even rupture to the construction unit brought inconvenience, in order to overcome these difficulties and ensure the operation of the pipeline, the use of demolition joints can only solve the problem.

 

Demolition joint overcomes various angles of pipeline displacement, different centers, expansion and contraction, and expansion. It can prevent the pipeline from leakage or damage due to excessive displacement of the compensating joint. It is mainly used for loose-fitting connection of pipelines that absorb axial displacement and bear pressure thrust within the allowable displacement range, and is suitable for connection with flanges on one side and welding with pipelines on the other side. The range can be free to expand and contract, locking the expansion amount to ensure the operation of the pipeline.
Single flange demolition joint provides convenience for the installation and removal of various water supply and drainage pipes, water towers, pumps, water meters and valves, and plays a good regulating role for long distance pipelines due to temperature difference expansion and contraction. Single flange demolition joint has good comprehensive performance, and it is widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, electric power and other basic projects.
