FABRIC EXPANSION JOINTS

Our intensive cooperation with competent and experienced manufacturers of fabric expansion joints enables us to deliver operationally effective and economically attractive solutions.

Fabric bellows are extremely flexible and can be made from a variety of special woven fabrics coated or laminated with selected elastomers or fluoropolymers. Fabric expansion joints are used to insulate, to avoid mechanical loads and to protect against abrasion. They offer advantages for the pipe work designer as they can absorb movements simultaneously in several directions. Further, they have almost no reactive forces and require little space. Fabric expansion joints are easy to customise to suit existing operating conditions and are easy to transport and install. In comparison to metallic expansion joints fabric offers almost unlimited flexibility, giving the pipe work designer more options.
Fabric expansion joints are installed in systems operating with low pressure and dry media.

DIMENSIONS

All sizes, with or without steel parts.
For installation in existing duct- and/or pipework the fabric expansion joints are supplied with either closed- or open ended band.

TYPES

Circular and rectangular in all sizes for temperatures up +1200ºC
and pressure up to 2000 mmwg.

MOVEMENTS

The movements that the units are capable of accepting can be singular or a combination of:

  • Axial movement (compression and extension)
  • Lateral movement
  • Angular rotation
  • Torsional rotation

A significant difference between fabric expansion joints and metallic- or rubber expansion joints is that fabric types can readily accept the torsion which is undesirable with metallic- and rubber expansion joints. Furthermore in addition to absorbing movements in the system, fabric expansion joints can also absorb vibrations and help to reduce or eliminate noise.

QUICK & SIMPLE INSTALLATION

We always supply complete solutions for quick and simple installation into the duct or pipework. When necessary due to transport or installation considerations we can supply fabric expansion joints in segments for later assembly at the jobsite.
