Page 14: Refrigeration Piping Installation
Refrigeration piping installation Brazing recommendations All interconnecting pipes should be of refrigeration grade, Maintain a fow of oxygen-free nitrogen through the system clean, dehydrated and must remain capped at both ends at a very low-pressure during brazing. Nitrogen displaces until installation. Even during installation, if the system is the air and prevents the formation of copper oxides in the left for any reasonable period (say two hours), pipes should system. -
