brazing under nitrogen
I have a question about brazing under nitrogen gas. I usually use nitrogen for VRV refrigeration pipe work with flow between 3 and 5 liter/min.
What's your opinion about it, is there a relation or a formula between the pipe diamater and the flow of the nitrogen gas ?
Thank for a prompt reply
