Good evening to everyone. Greetings from a new member. Just out of a refrigeration technical college with almost a year of working experience. This is my first post.
I need to verify the possibility of leaks in a number of sets of large diameter refrigeration copper pipes: 2.5 and 3 inches, according to the printing in the Armaflex-type insulation. The length of each line is between 30 to 45 meters. I have used nitrogen for this purpose in much smaller jobs, but never before in such a large scale. In the same place where these pipes are installed, there is a compressed air system for pneumatic machinery. The air passes through a mechanically refrigerated drier and several steps of filtration. Does anyone has any experience in using compressed air for leak search instead of nitrogen? Thank you for any comments.
