Gi Pipe 6m Length Galvanized Steel Water Pipe

Hot dip galvanized round pipe is on the basis of welding steel pipe for internal and external hot dip galvanized, so that the inner and outer walls of steel pipe are coated with zinc layer at the same time, greatly improve the corrosion resistance of steel pipe, up to about 20 times of ordinary steel pipe.

Galvanized pipe adopts sulphate electrogalvanized iron alloy process, which is perforated through the groove and the groove of the production line without any solution out or overflow.Each process of the production process is composed of a circulation system. The solution of each tank, namely acid alkali solution, electroplating solution, light and passivation solution, is only recycled without leakage or discharge to the system.There are only 5 cleaning tanks in the production line, which adopts the recycling and regular discharge, especially the production process of no waste water produced without cleaning after passivation.
