The reason for trying to drain off the water droplets inside and outside the galvanized steel pipe after cooling

After removing the galvanized steel pipe from the cooling water, it still needs to undergo passivation treatment. If the cooling water adhering to the inner and outer surfaces of the galvanized steel pipe is not removed, a large amount of water will be carried into the passivation solution, diluting its concentration. When the concentration falls below the specified level in the process, the passivation effect will be reduced. Therefore, before the galvanized steel pipe enters the passivation tank, it is essential to remove the water adhering to the inside and surface of the pipe.
