Single Sphere EPDM NBR CR Expansion Rubber Joint Flange Type
Product Description
Expansion Rubber Joint is a flexible piping connector designed to absorb vibration and noise, compensate for thermal expansion and contraction, and accommodate axial, lateral, and angular movement in pipeline systems. It is typically made from high-quality rubber materials such as EPDM, NBR, or NR, reinforced with fabric layers or steel rings, and equipped with flanged or threaded ends. Expansion rubber joints are widely used in water supply, HVAC, wastewater treatment, industrial, and marine applications to reduce stress on pipelines and equipment, improve system stability, and extend service life.
Performance characteristics
1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced rubber bellows provides long-lasting performance.
3. Corrosion Resistance: Resists aggressive environments and chemicals.
4. Noise & Vibration Reduction: Dampens vibrations and shock waves.
5. Ease of Installation & Maintenance: Compact design and standard flange connections facilitate installation and upkeep.
