Manufacturer Customized Pipe Expansion Joint Flange Type Rubber
Joint
Product Description
Rubber joint is generally composed of a smooth waveform compensation element
with rubber flanges at both ends and a metal flange. Metal flanges
often use loose sleeve construction. Designed to accommodate
rigorous operational demands, it effectively dampens vibrations,
isolates noise transmission, and prevents stress concentration in
piping connections. Customizable to adhere to international
specifications including ISO, ASTM, BS, and ASME, this joint
ensures seamless integration with global industrial standards. Its
compact single-bellow configuration offers installation versatility
across HVAC, chemical processing, water treatment, and power
generation systems, providing reliable performance under
fluctuating temperatures and pressures.
Performance characteristics
1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced Rubber Joint 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.
