Axial with loose flanges AX1BU

Advantages

 

  • Simple solution for compensation of temperature fluctuations
  • Compact and space saving solution
  • Relatively low cost
  • Simple assembly and pre-tensioning of expansion joints 

Disadvantages

  • Strong anchors and good guides are required
  • Large movements require utilization of several axial expansion joints
Higher costs for anchors and guides

Axial movement
Axial movement is a change in the length of the bellow. Due to the movements in the pipeline the expansion joint is either compressed or extended. This means that the compensator is shortened or lengthened. The built-in length of the compensator is within the maximum compression or the maximum extension. It is possible to make the pre-tension of the compensator, which means that the compensator is either compressed or extended to a given length, for instance 300 mm, and fastened with a pre-tensioning device. This pre-tensioning device ensures that the compensator has the required length until installation
