Fabric Expansion Joints
Fabric expansion joints are flexible elements capable to compensate largely without any stresses axial, lateral and angular movements in various piping systems. Appropriate designs are available to withstand vibration and torsion as well. Also, fabric expansion joints can occur concurrently throughout the pipelines for a better compensation.
Designing and manufacturing fabric expansion joints is a complex process which requires detailed information about the application, the working environment and the dimensions of the equipments or pipings. ROTH fabric expansion joints can be manufactured from one single layer of fabric or they can have several layers glued of sewed together according to each application requirements.
Applications
Although fabric expansion have joints various applications, ROTH fabric expansion joints are mainly used with gaseous media and/or bulk media in industrial areas such as:
- Coal, oil and gas-fired steam power plants;
- Flue-gas desulphurization systems (DeSOx)
- Nitrogen oxide removal systems (DeNOx)
- Waste incineration plants
- Chemical plants;
- Refineries;
- Cement and lime industry;
- Metallurgical plants;
- Painting and drying systems;
- Ventilation systems ;
- De-dusting and filter installations;
- Fire protection systems etc.
Backed by more than 30 years of practical experience and comprehensive test procedures, we are able to offer our clients the very best in consultation. The high quality of our fabric expansion joints is ensured by the choice of high-grade materials and their appropriate processing. Correct installation is another factor that determines the operational effectiveness of any fabric expansion joint. We will be pleased to advise you or to provide expert assembly engineers on request.
