OPERATIONAL EXCELLENCE DELIVERS ECONOMIC BENEFITS Our intensive cooperation with competent and experienced manu- facturers 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 advan- tages for the pipe work designer as they absorb movements simultane- ously in several directions, they have almost no reactive forces and require little space. Fabric expansion joints are easy to customize to suit existing operating conditions and are easy to transport and install. In comparison to metallic expansion joints fabric expansion joints offer almost unlimited flexibility and give numerous options for the pipe work designer. Fabric expansion joints are installed in systems operating with low pressure and dry media. The movements that the units are capable of accepting can be singular or a combination of: • Axial movement (compression and extension) • Lateral movement • Angular movement • 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. Further- more in addition to absorbing movements in the system, fabric expansion joints can also help to reduce or eliminate noise and to a limited degree they can absorb vibrations. We always supply complete solutions for quick and simple installation into the duct or pipework. When neces- sary because of transport or installa- tion logistics we can supply fabric expansion joints in segments for assembly at the jobsite. APPLICATIONS Fabric expansion joints are found in a wide range of industries including: • Chemical process plants • Cement manufacturing • Pulp and paper industry • Power stations • Refineries • Shipbuilding • Steel plants • Sugar plants • Gas turbine installations PRODUCT RANGE Types: Circular and rectangular Dimension: All sizes and 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. Temperature: Up to +1200°C Pressure: Up to 2000 mmwg
