Wholesale Fabric Smoke and Air Flue Duct Expansion joints Manufacturer, Factories
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.
For non metallic expansion joints, we provide 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 features 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 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 to 6000*6000 (larger size can be made), DN6000, meeting diverse industrial requirements. We also offer custom designs based on specific requests.
Key Features
Thermal Expansion Compensation: Multi-dimensional compensation, superior to metal joints which typically handle only one dimension.
Installation Error Compensation: Effectively eliminates inevitable system errors during pipeline connection.
No Reverse Thrust: Non-metal materials transmit no thrust, simplifying support design and reducing labor/material costs.
Resistant to Extreme Conditions: Fluororubber and silicone materials provide excellent high temperature and corrosion resistance.
Superior Sealing: Built with a complete assembly system ensuring virtually zero leakage.
Lightweight & Simple: Simple structure makes installation and maintenance highly convenient.

Frequently Asked Questions
1. What are fabric expansion joints used for?
They are primarily used in hot air and smoke pipelines to compensate for axial, transverse, and angular displacements caused by thermal expansion or vibration.
2. How do non-metallic joints compare to metal joints?
Non-metallic joints provide multi-dimensional compensation, whereas metal joints often handle only one dimension. They also offer better noise reduction and do not transmit reverse thrust.
3. What temperatures can these joints withstand?
Utilizing high-grade Fluororubber and silicone materials, these joints are designed for excellent high-temperature resistance suitable for smelting furnaces and power plants.
4. What sizes are available for the square fabric joints?
Standard sizes range from 200*400 up to 6000*6000. Large-scale custom sizes can also be engineered to meet specific industrial requirements.
5. Are these expansion joints corrosion-resistant?
Yes, the specialized non-metallic materials used are chosen specifically for their ability to resist corrosion in harsh industrial environments like petrochemical plants.
6. Is maintenance difficult for fabric expansion joints?
No, the structure is simple and lightweight, which makes both the initial installation and
