Multi-layer expansion joint

Multi-layer expansion joint

These multi-layer expansion joints take up movement in several directions simultaneously; they have almost no reactive forces and need little space for installation. They quickly adapt to existing physical conditions and are easy to transport and install.

Different factors to consider when choosing a multi-layer expansion compensator:

  • Movements
  • Design / Operating Temperature
  • Design / Operating Pressure
  • Chemical Resistance
  • UV Environment

Multi-layer expansion joint details

Many combinations of products may be used to fabricate the multi-layer joints such as:

  • Fluoroplastic membrane
  • Elastomer
  • Aluminium vapour barrier
  • PTFE
  • High temperature cloth (Fiberglass, Ceramic, Silica, etc.)
  • Insulation (Ceramic, Glass mat, Silica mat)
  • Stainless steel or inconel mesh
  • Teflon impregnated fiberglass tape
  • Etc…

The threads used in the conception of these joints are the following:

  • Pure PTFE thread
