the advantages of flange rubber joint are: small volume, light weight, good elasticity, easy installation and maintenance, can produce transverse, axial and angular displacement during installation, not subject to the different center of the pipeline, flange is not parallel, can reduce the noise transmission structure when working, strong vibration absorption ability.  

the advantage of flange expansion joint is that when the outside temperature changes, the pipe can make the pipe freely expand in the expansion range, lock the expansion amount, to ensure the safe operation of the pipeline.  

the ADVANTAGE of flange force transmission joint is that it can effectively compensate and alleviate the thrust of pipeline and blind plate, and facilitate the installation, maintenance and replacement of water pump and valve. It is the most ideal supporting product in pipeline installation and transportation industry.
