    Features & Benefits

    SR41 is a flexible rubber joint, abbreviated as rubber joint, is a joint composed of fabric reinforced rubber parts, flat flexible joints, metal flanges or threaded pipe flanges, used for pipeline vibration isolation, noise reduction and displacement compensation. It is a pipeline joint with high elasticity, high airtightness, medium resistance, and weather resistance.

    Flanged Flexible Rubber Joint SR41

    Prevents excessive movement of the joint caused by thermal expansion, pressure thrust, or other forces. It protects the joint from overextension or compression.

    Provides additional structural support to maintain alignment and stability under pressure or load.

    The outermost layer of the rubber joint that protects the inner layers from external environmental factors like ozone, weathering, and mechanical damage.

    The innermost layer of the joint, designed to resist chemical corrosion and abrasion caused by the conveyed fluid.

    Holds the flanges in place, ensuring proper sealing and mechanical stability.

    Increases the flexibility of the joint, allowing it to absorb vibrations, thermal expansion, and contraction.

    Reinforced fabric layers that provide the joint with the necessary strength to withstand internal pressure and mechanical forces.

    The flange on the connected piping that aligns with the integral flange of the expansion joint to form a secure connection. It can be customized by different standards or special request.
