1:introduction

 Fiber expansion joint has distinct advantages as they can accommodate relatively large movements and even some misalignment of flanges. They are also lightweight, easy to install and with the addition of internal insulation bolsters have good acoustic properties. Fabric expansion joints can be supplied fully assembled and fitted to support steelwork ready for insertion into ductwork. For retrofit applications, we can supply as factory joined or open for on-site joining where access is limited 

2:ZHW fiber expansion joint

ZHW fabric expansion joints are in use in Power Plants, Gas Turbine installations, Offshore

installations, Cement works, the Chemical Industry and many others. ZHW fabric expansion

joints are available in virtually any size and shape, from a range of proven standard

constructions or designed specifically for your application.

The combined temperature, pressure and media are all decisive factors in the selection of

fabric expansion joints. We offer 28 standard styles, covering every medium from clean air

to highly aggressive flue gases. The materials used for the individual layers of ZHW multi-

layer expansion joints and the number of layers vary according to the type of expansion

joint and the operational conditions.

3:Layers

For mechanical protection, the internal layer of Standard Fabric Expansion Joints is either

glass fabric or wire mesh.
Where medium temperatures are above 300°C, ZHW Fabric Expansion Joints are de-signed with

one or more layers of insulation material for thermal protection.
If the medium conveyed is aggressive, a gastight membrane serves as a chemical barrier. 
The outer layer primarily functions as a protection against ambient and mechanical

influences, and as a pressure reinforcement.
Flange reinforcement for mechanical and thermal protection of the fabric expansion joint in

the flange area.
The materials used for the above mentioned layers, vary according to the individual type of

expansion joint and the operational conditions.
