Shiya engineering, We are able to manufacture sizes ranging from DN40– DN9000. Our metal bellows can be produced to almost any material specification including stainless steel 304, 321, 316, 316Ti, Monel 800, Inconel 625, Inconel 800. We test all of our products to the highest standards using our state of the art NDT testing facilities using 2D and 3D CAD technology. Shiya engineering also offers a technical visit service so we can see what you need ourselves. “Non-Metallic/Fabric Expansion Joints are flexible connectors designed to provide stress relief in ducting systems by absorbing movements caused by thermal changes. They also act as vibration isolators, shock absorbers and in some instances to make up for minor misalignment of adjoining ducting or equipment.” Fabric Expansion Joints are typically designed for ducts where pressure is known, not more than 3 psi (2000 mm w/c) and temperature up to 1000oC. However, for higher temperatures, the duct itself needs to be internally insulated. Our capacity range in round expansion is from DN50 to DN9000, In rectangle & square any size up to 10 meter. And in Non metallic fabric expansion joints any size in round and rectangle, Also we manufacture Dismantling joints and dampers.
