How to distinguish the quality of epoxy resin coated steel pipe

the real epoxy resin coated steel pipe is the anti-corrosion macrostructure of the pipe. it uses electrostatic adsorption to electrostatically adsorb the modified epoxy resin powder on the inner and outer walls of the steel pipe. usually, companies that can say the same name are deceiving customers. , the product performance of the plastic-coated composite steel pipe has been recognized by the majority of customers, and the customers can distinguish it in real-time to prevent being cheated after cooperation, smoothness, and other characteristics.
