Expansion Joint Fabrics Configurations
Expansion joints fabrics made with Zetex and ZetexPlus fabrics can be configured to perform in a wide range of operating conditions. Depending on fabric choice, and the number of fabric layers, expansion joints can operate in environments up to 1500°F (816°C).
Use the application guide below to configure expansion joints for low heat, medium heat and high heat applications with Zetex and ZetexPlus fabrics.
|
Expansion joints for low heat service applications typically consist of three fabric layers.
- 1. High Temperature Fabric
- 2. Aluminized Vapor Barrier
- 3. Chemical Resistant Jacketing
|
|
For medium heat applications up to 900 °F (482 °C), a four-layered fabric configuration will take up excellent thermal expansion and vibration in air and exhaust gas systems.
- A. High-Temperature Fabric
- B. High-Temperature Fabric
- C. Aluminized Vapor Barrier
- D. Chemical Resistant Jacketing

|
Configure a 5-layered expansion joint made from Zetex ZetexPlus fabrics for high heat applications in the 1000 °F (538 °C) to 1500 °F (816 °C) operating range.
- A. High-Temperature Fabric
- B. High-Temperature Fabric
- C. High-Temperature Insulation
- D. Aluminized Vapor Barrier
- E. Chemical Resistant Jacketing

Applications
- Expansion joints made from Newtex fabrics have significantly reduced heat loss to in-line duct and piping process lines and doubled the average life of expansion joints in mining processes, and at energy power plants.
- Asian electric power utility companies use Zetex PTFE coated fabric for expansion joints. They are lasting five times longer than previous fabric expansion joints.
