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
