For air duct! New-type duct expansion joints

Product Description

duct Expansion Joints:Duct expansion joints have 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.

 

 

Zhonghaiwei® fabric expansion joints are in use in Power Plants, Gas Turbine installations, Offshore installations, Cement works, the Chemical Industry and many others. Zhonghaiwei® 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 many standard styles, covering every medium from clean air to highly aggressive flue gases. The materials used for the individual layers of Zhonghaiwei®  multi-layer expansion joints and the number of layers vary according to the type of expansion joint and the operational conditions.

The temperature capabilities range from **0º C to ****0º C and the pressure range from **0kPa to **0kPa.  Zhonghaiwei®  fabric expansion joints are also available as units including steel work and ready for installation.

All materials undergo intensive in-house testing before being released for production, the properties are verified by independent testing authorities Certificates.

Functions:

Fabric expansion joints are used for absorbing movements between joining connections in gas conveying ducts and pipe-lines. The movements can be caused by thermal expansion of the ducting system, wind conditions or vibrations from other system components or machines. In addition, fabric expansion joints can serve as seals and compensate for installation misalignments.

Duct Expansion Joints Advantages:

The implementation of fabric expansion joints provides a number of advantages, which are technically and economically important:
