China Fabric Smoke and Air Flue Duct Expansion Joints - Reliable Suppliers and Factory for Non-Metallic Solutions
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.
Features
-
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. Simple structure: Its body is light, structure is simple, installation and maintenance are convenient.

Frequently Asked Questions (FAQ)
What types of non-metallic expansion joints do you offer?
Shandong Hesper Rubber Plastic Co., Ltd. offers both fabric expansion joints and rubber expansion joints (rubber soft joints) to meet different pipeline requirements.
What are the main benefits of fabric expansion joints over metal ones?
Fabric expansion joints can compensate for multi-dimensional thermal expansion (axial, transverse, and angular), whereas metal joints typically compensate in only one dimension. They also eliminate installation errors, transmit no reverse thrust, and simplify the overall support design.
What materials are used to ensure temperature and corrosion resistance?
Our fabric expansion joints utilize high-quality Fluororubber and silicone materials in the non-metallic ring belt, which provide excellent high-temperature and corrosion resistance.
What shapes and sizes of fabric expansion joints are available?
We offer square, circular, single-turn, double-turn, angular, and other structures. Square sizes range from 200*400 to 6000*6000 (larger sizes can be custom-made), and circular sizes up to DN6000. We can also design and manufacture according to specific customer requests.
In which industries are these expansion joints commonly applied?
They are widely used in boiler plants, cement factories, steel mills, thermal and nuclear power plants, HVAC systems, petrochemical enterprises, glass and mineral wool industries, and fan systems.
