Union Type Double Sphere Flexible Rubber Joints

 

Description:

 

Rubber Expansion Joints are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.

Because of rubber has superior capability in resistance of acid, alkali, oil, and electrolytic, Rubber Expansion Joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical/Petrochemical, Marine, Power Generation, Pulp/Paper, Steel Mills and Water/Wastewater Treatment.
