Style 9400 Expansion Joints

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
