Wind leakage temperature
Thread Content
I would like to ask: in winter, in order to assess risks related to water presence, what does the temperature of the leak site measured represent? And what should be the target value for this temperature?

Dew point control for purified air at 0.7Mpa – below -40 degrees Celsius
What is the relationship between dew point and temperature and humidity?
The dew point is a temperature value; what is measured using a dew point meter is the saturated temperature of the instrument air. The higher the dew point temperature, the greater the water content, and the more likely the instrument air to contain water. We require the dew point of instrument air to be at -65°C; values around -50°C have also been seen. The lower the dew point, the safer it is, although this naturally depends on the adsorption capacity of the adsorbent
I wonder what major the original poster has? You haven’t studied principles of chemical engineering, have you? Dew point temperature is a concept related to the moisture content of air; it is the temperature at which water in the air begins to precipitate as dew. The higher the moisture content of the air, the easier it is for water to precipitate, and thus the higher the dew point temperature. Once water condenses and forms, various types of electrochemical corrosion accelerate, so it is necessary to monitor the dew point temperature.
So what is an appropriate value for controlling the dew point temperature?
It is advisable to keep it 20°C lower than the local minimum limit temperature; if it is too low, the processing cost will be very high
