Product Description

Different Types of   Constructions

We manufacture Fabric Expansion Joints  (Bellows) of virtually any size & shape, from a range of proven standard constructions or designed especially for defined application. It is essential that all the relevant parameters and conditions affecting Expansion Joints are taken into account.

REX has three basic types of Multi-Layer construction to meet the various needs of our customers

Type  1 for clean air systems
: ranging from simple air intake/exhaust on fans and blowers to high temperature air discharge from heaters.

Type 2 for gas with low acid content: used on Gas Turbine Exhaust and less severe flue gas systems.

Type 3 for gas with high acid content: for use in environments where the flue gas contains acids at temperature or acids that can form due to condensation at shut down.

Acid barriers are either PTFE impregnated glass cloth or PTFE foil thermally welded to ensure  tight seal.

Multi-layer fabric temperature range is from -50°C and 1090°C with a standard pressure range of ± 120" W.G

An important difference in the REX Multi-Layer Fabric is that we do not rely on an insulation pillow to reduce the temperature in contact with the element.

The Multi-Layer Fabric is always designed to withstand the temperature regardless of secondary insulation pillow.

Many competitive designs rely on this insulation pillow for primary protection of their element with disastrous results after several temperature cycles.

Distinct Advantages

  • Accommodate relatively large movements and even some misalignment of  flanges.
  • Light weight & 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 duct work.

For retrofit applications, we can supply as factory joined or open for  on-site joining where access is limited.
