Metal Expansion Joint

Pressure Balanced Expansion Joint
Solution to Many Excessive Loading Problems on Piping and Equipment
  • Absorb axial and small amounts of lateral movement
  • Eliminate pressure thrust
  • Reduce piping costs
  • Eliminate main anchors
  • No volume change
  • Stable at high pressures
  • Simple to manufacture

These types of expansion joints are used in application where main anchoring is not practical and in piping system where pressure loads are critical, and where complex axial and lateral movements are involved with limited space and also seen in piping connecting two load sensitive equipments.

2 types of pressure balanced expansion joints available depending on the installation location:

  • Type PB-I, Inline pressure balanced expansion joints
  • Type PB-E, Elbow pressure balanced expansion joints
