Application of Non-metal Fabric Expansion Joints
Corrugated Fabric Expansion Joints with revers are new kind of non-metal expansion joints. The typical advantages are lightweight, supple, hermetic, high working temperature, anti-corrosive,big compensation rate and easy installation. They are suitable for the flexible connection between different ventilation fans, ducts and pipework; can compensate the thermal deformation of pipework and release the pipework stress; reduce or weaken the vibration of the pipework; and make the installation of whole system easier.
Corrugated Fabric Expansion Joints are different from those traditional non-metal expansion joint. It is made of single layer or multiple layers of rubber and fabrics, laminated under high temperature and pressure; the revers is turned over and shaped once with special technics, which is different from the craftwork for producing traditional fabric expansion joints—- gluing, sewing, covering and flange pressing. And the special technics make our expansion joints overcome the traditional expansion joints’ weak points such as not-firmly laminated, not hermetic, leaking, heavy, hard for installation and maintenance.
Corrugated Fabric Expansion Joints connect to the flanges with its own rubber layer on the revers, the connection is very hermetic; and can sustain max 2MPa working pressure. The axial compression ratio, radial and rotational shifting are much better than traditional expansion joints. Our Corrugated Fabric Expansion Joints are very ideal for ventilation fans, pipework to reduce the system vibration, noise and stress. They are the best parts you should have for your system.
We use different kinds of fabrics to make the expansion joints according to our customers’ technical requirements and application environments, such as silicon rubber, fluorine rubber, Ethylene-Propylene-Diene Monomer(EPDM).
