Glavanized Steel Pipe Manufacturing
Galvanized pipe using sulfate electroplating of zinc-iron alloy technology, is the production line between the slot and slot are perforated without any solution out or overflow. The production process of the process consists of the circulatory system, the tank solution that acid-base liquid, electroplating solution, the light and passivation solution, only to not use the system to leak or discharge, the production line only 5 cleaning tank, Reuse of regular emissions, in particular, after the passivation is not washed without the production of waste water production process.
