Product Line Details

Pipe Expansion Joints isolate the blower or vacuum pump from other system components to allow for thermal expansion, pressure spikes and misalignment of the piping. The most common flanged rubber expansion joints feature single or double arched bellows constructed of molded elastomers. Standard single arch models from pdblowers are made of EPDM elastomer.

Functions of an Expansion Joint
-Reduces or eliminates flange loading on the blower
-Allows for thermal expansion of the blower casing (cylinder)
-Vibration isolation protecting the blower and piping system
-Reduces harmonics/sound transmitted down the pipeline
-Compensate for misalignment
-Accommodates directional movement

pdblowers uses Flanged Rubber Expansion Joints on many pressure and vacuum systems and we keep common sizes in stock ready to ship.  Contact us if you need a size or material not listed here.
