EPDM Single Sphere Rubber Expansion Joint Flange Type Rubber Expand Joint
Product Description
Rubber expansion joint is a highly versatile and reliable piping component that serves a crucial role in accommodating various movements within piping systems. Constructed with a reinforced rubber bellows shaped like a single sphere, this joint is engineered to absorb axial, lateral, and angular movements caused by thermal expansion, contraction, vibration, or settlement of the piping system. The rubber material, often reinforced with fabric plies or metal inserts, provides exceptional flexibility and durability, allowing the joint to withstand the rigors of demanding applications. By incorporating a single-sphere rubber expansion joint into a piping system, engineers can ensure system integrity, prevent leaks, reduce noise and vibration, and ultimately enhance operational efficiency and safety.
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.
