Our product range includes durable fabric expansion joints and versatile rubber expansion joints (also known as rubber soft joints). Designed to effectively accommodate axial, transverse, and angular displacements in pipelines, our fabric expansion joints boast unique advantages such as thrust-free operation, simplified support design, corrosion resistance, high-temperature durability, and excellent noise and vibration reduction. These features make them particularly ideal for use in hot air and smoke pipeline applications. Trust our expertise as a top supplier in China for all your expansion joint needs

Product Detail

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

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.
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.
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.
Better temperature resistance and corrosion resistance: The Fluororubber and silicone materials have good high temperature resistance and corrosion resistance.
Better sealing: There is a relatively complete production and assembly system, and the non-metallic fabric joints basically no leakage.
Convenience: Its body is light, structure is simple, installation and maintenance are convenient.

Frequently Asked Questions (FAQ)

Q1: What are the main materials used in fabric expansion joints?

Fabric expansion joints are mainly composed of a non-metallic ring belt (skin or cloth), heat insulation material, and a steel structure. Fluororubber and silicone are widely used due to their excellent high temperature and corrosion resistance.

Q2: What kinds of displacement can fabric expansion joints compensate for?

Unlike metal expansion joints which can only compensate in one dimension, fabric expansion joints can absorb axial, lateral, angular, oblique, and other multi-dimensional displacements simultaneously.

Q3: Why are fabric expansion joints preferred over metal expansion joints?

They offer multi-directional compensation, eliminate pipeline installation errors, transmit no reverse thrust (simplifying support design and saving materials), and provide superior noise elimination, vibration reduction, and corrosion resistance.

Q4: Can Shandong Hesper customize the size of the expansion joints?

Yes, we can design and manufacture expansion joints according to customer specifications. Our square sizes range from 200*400 to 6000*6000 (larger sizes can also be custom-made), and circular sizes up to DN6000.

Q5: In which industrial environments are fabric expansion joints typically installed?

They are highly suitable for hot air pipelines and smoke pipelines. Key applications include boiler factories, cement factories, iron and steel plants, smelting furnaces, incinerators, power plants, petrochemical enterprises, and air cleaning plants.
