Problems solved by technology

[0002] With the current rapid economic development, the surface protection of metal pipes has attracted more and more attention. Due to long-term harsh working environments, especially in some working environments that are outdoors for a long time and are prone to collisions, the adhesion of coatings on the surface of metal pipes , wear resistance and mechanical properties are getting higher and higher, but the adhesion, wear resistance and mechanical properties of conventional coatings are poor. With the development of science and technology in recent years, the surface coatings for metal pipes that meet the above requirements are increasingly unable to meet the needs and need to be solved urgently
