Fabric Expansion Joints:
These joints are generally used to neutralize thermal expansion and contraction along the paths that are commonly used for low pressure gas fluids. Fabric expansion joints are able to absorb movements on all planes simultaneously at many times, and even torsional movements can be repelled by these joints, and they can also correct non-axial flanges. It should be noted that under the same conditions, it is easier to repair, maintain, install and replace fabric expansion joints than other expansion joints. Fabric expansion joints with rectangular, circular, and etc. sections are available. They are also lightweight, and with easy installation, it is possible to add good acoustic properties by adding a layer of internal insulation. Fabric joints are used for a range of temperatures ranging from -50 to 1200+ degrees Celsius. Fabric joints can also be used as seals, and non-axial compensation of installations. Fabric fittings are available in any size and shape that are either standard or are made to meet the needs of the employer. The determining factors in choosing a fabric joint are: fluid type, temperature, pressure, intermediates (environment) and etc.
The materials used for every single layers of a multilayer fabric joint and the number of layers are in accordance with the type of expansion joint and the working conditions and are changeable. It is worth noting that the Erteashat Sanate Arak Co. supplies its consumer goods from reputable European companies such as Hiltex and Thermal Ceramic.
