Preventing freezing of compressed air pipes in northern regions during winter
Thread Content
Gentle masters! Are there anti-freezing measures for compressed air pipes in the northern regions? Seeking help!
The day before yesterday, the 150-mm pipeline here froze solid. At the lowest point of the pipeline, install electric heating, provide local insulation, add condensate drainage systems, and carry out regular drainage.
For compressed air lines, if they are pressurized air lines that have not been dried, insulation is required; as for heat tracing, it depends on the ambient temperature.
It mainly depends on the relationship between the dew point temperature and the lowest temperature
