Fabric Expansion Joints

Fabric Expansion Joints


Insaplex manufactures a range of Fabric Expansion Joints (bellows) used in flue gas ducts, process gas, etc., for accommodating movements at medium to high temperature conditions. These bellows are manufactured using different types of raw materials to suit the customer requirements. With the infrastructure facilities already available in-house, coupled with the experience and knowledge in producing various types of rubber and metallic expansion joints, the company is confident of meeting the customers’ requirements to the entire satisfaction both technically and commercially. Insaplex fabric expansion joints (FE joints) are robust highly flexible expansion joints, constructed from layers of synthetic cloth embodying a pressure membrane of reinforced PTFE. They are cost effective particularly in low pressure application up to 14.7 PSIG.

Insaplex – IPX joints are a unique combination of sandwiched layers of synthetic cloth, impregnated with different compounds. The layers include PTFE film – a material inert to chemical attack. The layers act together to insulate and contain high temperatures without causing damage to the joint, and are designed for continuous service at temperatures up to 700°C, and 1000°C with refractory lining. Insaplex fabric expansion joints are versatile and can be used to absorb a number of movements separately or in combination. These movements are axial, lateral, angular and torsional. The flexible construction of the joints makes it an ideal solution for noise and vibration absorption.
