Issues with the pressure of steam pipelines and antifreeze addition to the pressure guiding tubes of differential pressure transmitters
Thread Content
The insulation of pressure and differential pressure transmitters in the steam pipelines has never been properly implemented; the pressure guiding pipes keep freezing. Now we are thinking about filling these pipes with antifreeze to see if that will help If possible, which antifreeze should be chosen? Glycerin? Ethylene glycol or? Since it is a steam pipeline, could antifreeze get into the steam pipeline? What other things should be noted? Thank you!
We added green antifreeze to the car, and so far we haven’t encountered any problems.
What exactly is automotive antifreeze? Could it penetrate into the subsequent steam piping network and cause damage to the equipment? :'(
Antifreeze shouldn’t be corrosive, right? It was purchased specifically for use in Volkswagen vehicles, haha
Ethylene glycol is miscible with water; after emptying the isolation tank and filling it to the migration range, it can be used for a long time
The pressure guide tube can be installed inside the house or insulated; there should be no problem with that. I’m not sure what the outdoor temperature is like where the poster lives
It is better to use as little isolation fluid as possible, as it can cause problems in subsequent processing stages.
Currently it’s installed outdoors with steam heating; it works fine at temperatures around minus ten degrees. But these past couple of days the temperature has been minus twenty to thirty degrees, and it can’t handle that
It’s also below minus 20 degrees here; as long as proper heating and insulation are in place, there are basically no problems. The heating pipes used are 18-inch diameter tubes
