The anti-corrosion steel pipe coated with epoxy resin inside and outside is a steel plastic composite pipe made from spiral steel pipe or seamless steel pipe as the substrate, using sandblasting chemical dual pre-treatment, preheating, internal and external coating, curing, post-treatment and other processes. The anti-corrosion steel pipe coated with epoxy resin both inside and outside has strong corrosion resistance and mechanical properties, good chemical stability and water resistance, and has functions such as reducing resistance, corrosion resistance, and compression resistance.
