The issue of steam pipe rise height
Thread Content
The local minimum temperature is -25°C. I currently have a steam pipe with a DN50 diameter, insulated with 50mm of rock wool. I was wondering whether it’s possible to use this pipe to reach a height of 170 meters on the tower, and whether the steam will turn into water under such conditions
This requires calculation; you can refer to the second volume of the Chemical Process Design Manual, which contains calculations related to heat transfer through insulation
You need to consider the steam superheat; if it’s saturated, you have to set the drain at a lower level

It’s saturated steam. I did a rough calculation: rising 170 meters results in only a temperature drop of 2-3°C, with a pressure loss of around 20 kPa. I’m not entirely sure if this is correct
