Fabric Expansion Joint

Fabric Expansion Joint is a flexible Joint which is specifically designed to withstand physical elongation on a ducting system caused by the increase of temperature, Thus, the primary function of Fabric Expansion Joint is to reduce the stress level applied to the ducting system due to these changes. Apart from its main function, Fabric Expansion Joint has other functionalities such as :

  • To connect ductings with misaligned conditions.
  • To withstand vibrations
  • Shock Absorber

In general, a Fabric Expansion Joint is comprised of the following basic materials :

  • Fabric Materials
  • Synthetic Elastomers
  • Insulation Material
  • Fluoroplastics

Industry Application

Fabric Expansion Joint are widely used in the Power Plant Industry. However, Continuous development in Design Concept, combined with the dynamic creativity of our Design Frame has put  3 Star Fabric Expansion Joints as a highly promising option to be widely used in many other applications. Our Fabric Expansion Joints have been applied in the loop of many other Major industries such as :

  • Pulp and Paper Plants
  • Power Plants
  • Refineries (Oil & gas)
  • Steel Mills
  • Foundries
  • Cement Plants
  • Food Processing, and many others

Advantages of Fabric Expansion Joint

Fabric Expansion Joint extra can withstand bigger  and more complex type of movements. Pressure thrust and total spring will only give abd extra load from the lowest spring rate to the Anchor Side or Fix Point. 3Star™ Fabric Expansion Joint can withstand extreme temperatures or more than 2000∞F  , resistance by combining and applying the correct materials such as high temperature insulation products and others.


Fabric Expansion Joint can be designed for application with extreme temperature and corrosive media. However, it is only applicable for low pressure application (max 0.35 Bar). For application that require higher operating pressure, please do a prior consultation with our Design Engineers.
