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.
