Strict Quality Control
1.Quality control standard
Punching Fin：Fins should be straight and clean,shouldn’t have cleft and glitch.
Bending Tube:the tubes should be clean and full,the tube surface can't be concave .
Expanding tube:plates and fins should be fastened with tubes,plate is flat,don't have copper tube lay bare.
Welding:U-tube and header should be clean and full,no morhps,tube's surface won't be oxidzed.
Water test：fulling 5MPa gas，testing 5 minutes
Helium test： fulling 5MPa gas，Leakage rate≤1g/m
Pressure test:fulling 28MPa gas for 24 hours,pressure won’t change after 24H.
Bending tube：Tubes should be clean and full,tube surface shouldn’t be concave.
