Type:
in-line pressure balanced expansion joint
It is composed of two working bellows at both ends, a balance bellows in the middle, tie rods, end plates and other structural parts. It is mainly used to absorb axial displacement and balance the pressure and thrust of the bellows.
bypass in-line pressure balanced expansion joint
Composed of two identical bellows, end ring, head, outer tube and other structural parts, it is mainly used to absorb axial displacement and balance the pressure and thrust of the bellows.
external pressurized in-line pressure balanced expansion joint
It is composed of two working bellows bearing external pressure, a balance bellows bearing external pressure, and end pipes, connecting pipes, outer pipes, end ring components and other structural parts, which are mainly used to absorb axial displacement and balance the pressure and thrust of the bellows.
Feature:
1.Simple to manufacture
2.Stable at high pressures
3.Absorbs small amounts of axial and lateral movement
4.Eliminates change in pressure
5.No main anchors required
6.Conserves space
Application:
Pressure balanced expansion joints are used with low pressure turbines, with
condensers and also with pumps and other equipment, that may be susceptible to
pressure loads
