17.Contrast
1)Passivation corrosion
First,passivation corrosion is different form the physic rust preventing,passivation utilize the active principleof metal. after the passivation, the surface of the pipe will form a inertcompound .
to achieve the long-time rust.
After thepassivation, not only can improve the corrosion resistance, service life andenhancing the adhesion strength of the coating and the base metal, and also canincrease the decoration of the surface of the parts.
2)Oiled processing
Oiled processing before shipping is better, notoiled pipe will be more likely rusting in the transit.
Washing before using ,not affected can not clean.
