Professional China Hinged Expansion Joint - Fabric Smoke and Air Flue Duct Expansion joints – HESPER

For non metallic expansion joints, our company (Shandong Hesper Rubber Plastic Co., Ltd.) have fabric expansion joints and rubber expansion joints(rubber soft joints). Fabric expansion joints can compensate the axial, transverse and angular displacement of the pipeline. It has the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise elimination and vibration reduction. It is especially suitable for hot air pipeline and smoke pipeline.

Fabric expansion joints mainly composed by non-metallic ring belt(skin or cloth), heat insulation material and steel structure. Our company’s fabric expansion joints have square, circular, single-turn, double-turn, angular and other structures for your choice,they can absorb axial, lateral, oblique and other displacements at the same time. Their square size is from 200*400~6000*6000 (larger size can be made), DN6000, can meet the requirements of users in all aspects. We also can design and make according to customers’  requests.

1. Compensation for thermal expansion: It can compensate for multi-dimensional directions, which is much better than the metal expansion joints which just can only compensate in one dimension.

2. Compensate installation error: Since the system error is inevitable in the process of pipeline connection, the non-metallic fabric joints can better eliminate the installation error.

3. No reverse thrust, because the main material is non-metal, there is no thrust transmission. Using non-metallic fabric expansion joints simplifies the design, avoids using large bearings, and saves a lot of material and labor.

4.Better temperature resistance and corrosion resistance: The Fluororubber and silicone materials have good high temperature resistance and corrosion resistance.

5. Better sealing: There is a relatively complete production and assembly system, and the non-metallic fabric joints basically no leakage.

6. Its body is light, structure is simple, installation and maintenance are convenient.
