Product Description
6 Inch Expansion Joint PN10 PN25 Flanged Expansion Joint Pipe Fitting
6inch PN10 PN25 Water Plant Flexible Stainless Steel Shock-absorbing Rubber Expansion Joint double sphere
Double ball rubber joint:
Used for displacement compensation, vibration reduction, noise reduction, and installation error absorption in piping systems, featuring a double corrugated design; suitable for high-pressure, large displacement, and strong vibration critical pipelines.
Advantages of Double Ball Rubber Joints
- Superior Displacement Compensation
Three-dimensional compensation: axial ±15 mm + lateral ±10 mm + angular ±5° (under DN100 conditions)
Comparative Advantage: 40% improvement in compensation capacity compared to single-ball joints, no additional hinge brackets required - Excellent Vibration Damping and Noise Reduction
Vibration transmission rate ≤5% (tested data, single-ball joints approximately 15%)
Case Study: Noise levels in a power plant's pump room reduced from 95 dB to 75 dB - Long-Term Fatigue Resistance
Dynamic Lifespan: ≥5,000 full displacement cycles (GB/T 26121 standard)
Enhanced Design: Double-layer steel wire skeleton
