Expansion Joints
Elastomeric expansion joints are installed between pipe flanges to accommodate pressure loads, relieve movement stresses, counteract thermal expansion and contraction, reduce noise, isolate vibration and compensate pipe misalignment.

Major usage groups are:
Air conditioning, heating and ventilating systems
Central and ancillary power-generating stations
Industrial process piping
Sewage disposal and water treatment plants
Marine service
