Vibration and noise reduction is one of the properties of rubber joints
Rubber joints installed in the pipeline can reduce the vibration and noise of the pipeline system and can fundamentally solve the problems of interface displacement, axial expansion and misalignment of various pipelines.
 
Rubber soft joints can reduce noise by 15 to 25 decibels in pipeline use. They are devices for noise and vibration control. Rubber joints can withstand high internal water pressure, can be axially stretched or compressed, and can move laterally without deformation. Depending on the product, the amount can be several millimeters to more than 20 millimeters, and the ends of the joint can be deflected at an arbitrary angle of 15°.
 
Structure of small pressure bendable rubber soft joint 1. rubber pipe body 2. nylon cord fabric lining 3. hard steel wire skeleton 4. flange stressed in steel pipe engineering instead of sleeve type expansion joint, it can also be used in assembled reinforced concrete pipes, it is used as an installation part to adjust the installation size.
