Overview of Fabric Expansion Joint

ZHW fabric expansion joint Series RS801 are installed as flexible connections in air, duct and flue gas piping systems to take up or compensate for thermal expansion, vibrations and misalignments.

By combining different materials and taking into consideration the thermal, chemical and mechanical resistance as well as the fatigue properties of the materials, our designers provide the optimum solution both in technical and economical respect. ZHW fabric expansion joint series RS801 are used in conventional power plants fired with coal, oil and gas turbine systems.

Description

ZHW fabric expansion joint also known as non-metallic compensator. The main materials are fabric, rubber, high temperature resistant materials. It can offset the vibration of the fan, air duct operation and pipeline deformation.

ZHW fabric expansion joint series RS801 advantages:

  • Compensate for movements in several directions simultaneously
  • Almost no reactive forces
  • Requires little space for installation
  • Easily adapts to existing physical conditions
  • Easy to transport
  • Minimum heat loss due to good insulation
  • Cold on the outer layer during operation to protect employees on site
  • Proven technology
