Kynol Fiber Gland Packing: The Ultimate High-Temperature Sealing Solution
Industry-Proven Performance
When ExxonMobil’s Baton Rouge facility faced $18,000 daily losses from steam leaks, Hongwo’s Kynol fiber gland packing became their asbestos-free solution. Field data confirms:
Extreme Condition Performance:
- 528°C continuous operation (cherry-red boiler pumps)
- 0.02 in³/min leakage rate (API 622 Cat 3 certified)
- Zero hardening in 45% caustic environments
Documented Case Studies:
✓ Dow Chemical: Resolved ethylene cracker leaks in 48 hours
✓ BASF Geismar: Extended repacking intervals to 5 years
✓ Delayed Coker Service: 7x lifespan vs graphite packing
