Your consultants are asking you to pass nitrogen through copper pipes while brazing to prevent oxidation inside the pipes. These pipes are for refrigerant. Is this a regular practice?
AnswerPumping nitrogen through refrigerant piping during brazing is an excellent practice. The reason is that nitrogen helps to prevent the buildup of oxide scale on the inside of the pipes during the brazing process. Refrigerant is a natural cleaning agent, and as it is being pumped through the pipes it will pick up the scale and contaminate the refrigerant. It is possible that this will damage to the compressor.
