Advantages of Ceramic Composite Insulation Seal Sleeve
Dual Performance Combination
- Metal outer ring: Impact resistant, easy to install; flange / thread connection available.
- Ceramic inner ring: Insulation resistance >10¹²Ω, arc resistance ≥180kV/cm, prevents current leakage.
Экстремальная устойчивость к окружающей среде
- Operating temperature: -60°C to 1000°C; short-term up to 1200°C (Si₃N₄ type).
- Resists acid, alkali, oil, steam; compatible with pH 0–14 corrosive media.
Zero Leakage Sealing
- Hermetic metal‑ceramic sintering; helium leak rate <1×10⁻⁹ Pa·m³/s; pressure resistance ≥50MPa.
Customized Design
- Bore: Φ5–50mm; outer diameter: Φ20–200mm; thickness: 5–50mm.
- Conductive / insulating coating, shock-absorbing layer available.
