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
