Fabric Expansion Joints, Bellows, Non Metallic Expansion Joints

Listing ID #570211

We are offering fabric expansion joints, bellows, non metallic expansion joints etc.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
üaccommodate relatively large movements and even some misalignment of flanges.
ülight weight & easy to install and with the addition of
üinternal 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.
