5) Use the reducing valve to adjust the nitrogen

gas flow speed to 0.05 m

/hour or 0.02 MPa

(0.2 kgf/cm

6) After the steps above, keep the nitrogen gas

flowing until the pipe cools down to a certain
extent. (Temperature where the pipe is cool
enough to be touched by hands)

7) Remove the flux completely after brazing.
