Product Description
Performance Characteristics
Key Features & Benefits
- Enhanced Flexibility: Double-sphere design accommodates pipeline displacement from earthquakes, temperature changes, and land subsidence, protecting system integrity.
- Superior Weather Resistance: Specially formulated rubber maintains stable physical and chemical properties across extreme temperature ranges (-40°C to +80°C).
- Advanced Sealing: Special internal structure prevents media leakage and blocks external contaminants, extending pipeline lifespan.
- Low Flow Resistance: Smooth inner wall design minimizes energy consumption and reduces noise pollution.
- Vibration Dampening: Effectively absorbs pipeline vibrations, creating quieter working environments.
