Heat tracing system for freeze protection of process piping
Self-regulating electric heat tracing for cold-climate operations
-15 °C
Freeze protection maintained at design ambient
24/7
Continuous process continuity in winter
⚠️ The operational challenge
- •Severe pipe freezing on winter nights (-10 °C to -15 °C)
- •Operations stalled until midday natural thaw
- •Ice expansion causing leaks and ruptures
- •Prior steam methods caused thermal shock and flange failures
💡 Engineering solution
- ✓Design with self-regulating heat-trace cable (≈25 W/m at 10 °C)
- ✓Longitudinal installation with aluminum tape for heat transfer
- ✓Mineral-wool insulation with weather jacket
- ✓Ambient and line thermostat automation
🛠️ Equipment & technologies supplied
