In-Line Pressure Balanced Rectangular Expansion Joint
A
pressure balanced expansion joint accommodates axial and lateral
movements and counteracts the bellows pressure thrust. An additional
bellows is incorporated into the unit and is subject to the line
pressure to generate a force equal and opposite to that on the main
bellows. Tying these bellows together neutralizes the pressure load on
the unit.
Features
Features
- Does not transfer the thrust caused by the internal pressure to the pipes or adjacent equipment
- Absorbs axial and lateral movements
- Eliminates change in pressure
- No main anchors required
- Pressure forces remain in balance
