Customized Pipe Expansion Joint Flange Type Teflon Bellows
Product Description
Teflon bellows integrates advanced material science to solve thermal mismatch challenges in high-performance systems. The PTFE liner's negative coefficient of thermal expansion (-10.5×10⁻⁵/°C) counteracts the positive expansion of metallic piping, reducing residual stresses during temperature excursions. Combined with ASME BPE-compliant corrugated bellows, the assembly maintains structural integrity under vacuum conditions (<10⁻⁶ Torr) and full vacuum cycles. Certified for fire-safe applications (ASTM E119), the stainless steel reinforcement ensures containment integrity even during catastrophic failure scenarios. This makes it particularly valuable in oil refinery reformers, solar thermal energy systems, and chemical vapor deposition reactors where thermal shocks are routine.
Performance characteristics
1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced rubber compensator 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.
