Pressure test of thermal oil pipeline
Thread Content
For the pressure test of the heat transfer oil pipeline in a certain factory, the design document requires water pressure test and steam purging. However, there was no steam at the site, so the owner requested to use thermal oil for pressure testing. Isn’t this too expensive?
It would be nice if the owner doesn't think it is expensive..... If there is no steam, is there air or nitrogen?
There is wind or nitrogen. It is better to use steam to purge thermal pipes.
Isn't there none at the scene? Then just listen to the owners ;P If you don’t know how to use the heat transfer oil, you should pay for it...

Steam is purging. There is no steam and thermal oil is used for pressure tests. Is there any connection between the two? I didn't understand
The design documents require pressure testing with water and steam purging. There was no steam, so the owner asked for a pressure test using thermal oil (they arranged purge by themselves), and then a contact sheet was issued. Since thermal fluid is very expensive, I was curious as to how they operated it. These must be submitted to the Pot Inspection Office for review.
I have the same problem and I don’t want to purge it after I experiment with thermal oil? Yingga is irreplaceable
It seems confusing, but there is no problem in using thermal oil instead of water for pressure test. What does it have to do with steam? No need to purge after using thermal oil? According to regulations, the pressure should be tested first and then purged.
There is a saying that thermal oil is afraid of water, and it is afraid that the water will not dry out after the hydraulic pressure test, right?
