Single Sphere EPDM NBR CR Expand Joint Flange Type Flexible Bellows
Product Description
Single Sphere EPDM NBR CR Expand Joint Flange Type Flexible Bellows is a high-performance rubber expansion joint designed to provide excellent flexibility, vibration absorption, and noise reduction in industrial piping systems. The single sphere structure allows effective compensation for thermal expansion, axial compression, lateral movement, and angular displacement, helping protect pumps, valves, and pipelines from mechanical stress and operational damage. Manufactured with premium EPDM, NBR, or CR rubber materials, the flexible bellows can be selected according to different working environments and media requirements. EPDM is suitable for hot water, steam, and chemical resistance applications; NBR offers superior resistance to oil and petroleum-based media; while CR (Neoprene) provides excellent weather, ozone, seawater, and abrasion resistance. The flange type connection ensures easy installation and compatibility with international standards such as ANSI, DIN, JIS, and BS. Widely used in water treatment systems, HVAC projects, marine engineering, chemical plants, and industrial pipeline systems, this flexible bellows expansion joint delivers reliable sealing performance, durability, and long service life under demanding operating conditions.
Performance characteristics
1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced Expand 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.
