HA Type
expansion joints

Features

  • Elbow type pressure balanced expansion joints.
  • Pressure thrust eliminated by means of force balancing design principle.
  • Designed to apply minimum forces on connecting, load sensitive equipment.
  • Mainly for axial and lateral movements.

Advantages

  • No need for main anchors to obtain pressure thrust load.
  • Minimum load transferred onto connecting equipment – force balancing principle not affected by system pressure fluctuations.
  • Highly customizable design: Bellows geometry, Material options and combinations.
  • Multiply bellows with low spring rate and high cycle life.

Operating range

Diameter: DN 100 ... 1,000 (4" ... 40”)
Temperature: ... 550 °C (1,022 °F)
Pressure: max. 50 barg (725 PSIG)
