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. Under normal conditions, epoxy resin powder coated steel pipes can resist corrosion from various chemical media such as acid, alkali, and salt, ensuring the service life of the pipes.
