Epoxy resin powder coated steel pipe is made by coating the surface of the steel pipe with epoxy resin powder and curing it through high-temperature baking. Compared to traditional steel pipes, epoxy resin powder coated steel pipes have excellent corrosion resistance. Due to its surface being coated with epoxy resin, it can effectively isolate the direct contact between the steel pipe and the external environment, avoiding the problem of corrosion caused by oxidation of the steel pipe.
