Single Sphere EPDM NBR CR Expand Joint Rubber Flanges

Single Sphere EPDM NBR CR Expand Joint Rubber Flanges

Product Description

Rubber Flanges are flexible pipe connectors manufactured with EPDM, NBR or CR elastomer, reinforced by multi-layer nylon cord and steel wire rings. Equipped with carbon steel/stainless steel floating flanges, they are widely installed between pumps, chillers and piping systems to absorb axial, lateral & angular displacement, isolate vibration, reduce pipeline noise and compensate thermal expansion.

EPDM version: For hot/cold water, seawater, acid & alkali solution, outdoor HVAC systems
NBR version: Excellent resistance to mineral oil, diesel, hydraulic fluid and edible grease
CR neoprene version: General-purpose for compressed air & mixed light oil-water medium

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.
