　　Internal and external epoxy coated steel pipes

　　Epoxy powder anti-corrosion steel pipe manufacturer, anti-corrosion process of epoxy powder. Treatment principle of anti-corrosion process: The quality of pre-treatment has a great impact on the performance of the coating. There are many examples in the actual painting process where the expected anti-corrosion effect cannot be achieved due to poor pre-treatment. Especially for many high-performance anti-corrosion coatings, only by strictly following their respective requirements can a normal coating be formed, achieving the expected anti-corrosion protection effect. Steel substrates must undergo rust removal, oil removal, and phosphating treatment. The thickness of the anti-corrosion coating must exceed its critical thickness in order to provide protection. If the primer is left for too long before the topcoat is applied, it will be difficult to adhere and affect the overall protective effect.

　　New process of epoxy powder impregnation: Epoxy powder has always been coated using electrostatic spraying technology. Due to adhesion issues, the impregnation process of epoxy powder has not been widely used. In recent years, with the successful development of specialized phosphating solution for three coconut epoxy powder impregnation, the adhesion problem of epoxy powder impregnation process has been overcome, and the emerging process of epoxy powder impregnation has begun to be promoted. Epoxy powder anti-corrosion steel pipe manufacturer, the function of epoxy powder pipeline anti-corrosion is twofold: anti-corrosion and drag reduction. One is mainly used on gathering and transportation pipelines, sewage treatment and reinjection pipelines with severe corrosion in oil fields, to extend the service life of pipelines and provide guarantees for oil development and production. It is usually small in diameter and short in distance. The internal coating technology aimed at reducing drag and energy consumption is applied in the West East Gas Pipeline Project in China.
