Expansion joints are installed in a piping system to absorb vibration and shock.
A rubber expansion joint is a flexible connector manufactured from natural or synthetic elastomers, technical textiles and metal reinforcements.
Rubber expansion joint can also be called flexible rubber joints, rubber soft connections, soft joints, flexible rubber joints, rubber expansion joints, shock absorbers, etc. They are pipeline joints with high elasticity, high air tightness, medium resistance and climate resistance.It can reduce the vibration and noise of pipeline, and compensate the thermal expansion and contraction caused by temperature change.
we produce rubber expansion joints as below:
Flexible Rubber Joint
According to the connection method, there are three kinds of flange type, fixed flange type and thread type; according to the structure, it can be divided into five types: single sphere, double sphere, different diameter body, curved sphere and wind pressure coil. The tubular rubber piece is composed of inner and outer rubber, ply and traveler, and is formed by vulcanization molding and loosening with metal flange or parallel joint. This product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes, and is widely used in various piping systems.

Pipe expansion joints are also known as compensators, as they 'compensate' for the thermal movement.
However should site conditions demand a unique solution then end connections can be adapted to most applications.
