TB Type expansion joints

These in line pressure balanced expansion joints are designed to apply minimum forces onto connecting, load sensitive equipment. These expansion joints are made for mainly axial and lateral movements.

Product Description

Features:
  • In line pressure balanced expansion joints.
  • Pressure thrust eliminated by means of force balancing design principle.
  • Designed to apply minimum forces onto connecting, load sensitive equipment.
  • Mainly for axial and lateral movements.
Benefits:
  • No need for main anchors to obtain pressure thrust load.
  • Minimum load transferred onto connecting equipment - 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.
