Rubber Expansion Joints
Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:
Absorb movement
Improved thermal stability
Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
Reduce mechanical noise
Compensate for misalignment
Eliminate electrolysis between dissimilar metals
They are ideally suited for hundreds of applications in a wide range of industries, including:
Power Generation
Pulp and Paper
Chemical Processing
Water/Waste Water
Marine
Mining
Heating, Ventilating, and Air Conditioning
