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.
