3.7 Brazing
Care must be taken to prevent oxide forming on the inside of copper piping during brazing. The presence of oxide in a refrigerant
system adversely aects the operaon of valves and compressors, potenally leading to low eciency or even compressor failure.
To prevent oxidaon, during brazing nitrogen should be owed through the refrigerant piping.
Notes for installers
Warning
▪ Never ow oxygen through piping as doing so aids oxidaon and could easily lead to explosion and as such is extremely
dangerous.
▪ Take appropriate safety precauons such as having a re exnguisher to hand whilst brazing.
Flowing nitrogen during brazing
▪ Use a pressure reducing valve to ow nitrogen through copper piping at 0.02-0.03MPa during brazing.
▪ Start the ow before brazing starts and ensure that the nitrogen connuously passes through the secon being brazed unl
the brazing is complete and the copper has cooled down completely.
▪ When joining a shorter secon of piping to a longer secon, ow nitrogen from the shorter side to allow beer displacement
of air with nitrogen.
▪ If the distance from the point where nitrogen enters the piping to the joint to be brazed is long, ensure that the nitrogen is
owed for sucient me to discharge all the air from the secon to be brazed before commencing brazing.
