Background
Corrosion protection of pipes refers to measures for slowing down or preventing corrosion and deterioration of pipes under chemical and electrochemical actions of internal and external media or by metabolic activities of microorganisms. The coating is uniformly and densely coated on the surface of the derusted metal pipeline to isolate the derusted metal pipeline from various corrosive media, and is one of the most basic methods for pipeline corrosion prevention. However, in the coating process, the pipeline is often too large to be uniformly coated in all directions, so that the pipeline coating process is unqualified.
