China Fabric Expansion Joints Suppliers - High-Quality Duct Expansion Joints from Reliable Factory

Shandong Hesper Rubber Plastic Co., Ltd. is a leading factory and supplier based in China, specializing in non-metallic expansion joints. Our product range includes high-quality fabric and rubber expansion joints (also known as rubber soft joints) designed to effectively accommodate axial, transverse, and angular displacements in pipelines. These expansion joints are engineered to eliminate thrust, thereby simplifying support designs. With excellent corrosion resistance, high-temperature tolerance, and capabilities for noise elimination and vibration reduction, our fabric expansion joints are particularly well-suited for hot air and smoke pipelines. Trust our China-based factory to provide reliable solutions for your piping needs

    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 & 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)
    Q What types of non-metallic expansion joints does Shandong Hesper supply?
    Shandong Hesper Rubber Plastic Co., Ltd. supplies both fabric expansion joints and rubber expansion joints (rubber soft joints) for industrial applications.
    Q What displacements can fabric expansion joints compensate for?
    Fabric expansion joints can simultaneously compensate for axial, transverse, angular, lateral, and oblique displacements in pipelines.
    Q Why are fabric expansion joints better than metal ones?
    Unlike metal expansion joints which can only compensate in one dimension, fabric expansion joints offer multi-dimensional compensation, eliminate installation errors, transfer no reverse thrust, and are lighter and easier to install.
    Q What sizes of fabric expansion joints can you manufacture?
    We offer square sizes ranging from 200*400 to 6000*6000 (larger custom sizes are available upon request) and circular sizes up to DN6000.
    Q Do your non-metallic joints have good sealing properties?
    Yes, thanks to our complete production and assembly system, our non-metallic fabric joints basically have no leakage.
    Q What materials are used to ensure temperature and corrosion resistance?
    We utilize Fluororubber and silicone materials in our fabric expansion joints to ensure excellent high-temperature and corrosion resistance.
