Cold-drawn seamless steel pipe rusting is also a common problem, but rusting will affect the service life. At present, the corrosion problem can not be fundamentally solved. Some preventive measures can be taken to minimize the degree of corrosion. Tool rust removal is one of the methods, but it is not a long-term solution, but also can only be taken to inhibit the diffusion of cold-drawn seamless steel pipe after rust. The tool used by the cold-drawn seamless steel pipe manufacturer can not solve the problem in time. Sometimes the effect of tool rust removal is not very ideal, and it will also destroy the surface of the cold-drawn seamless steel pipe. At this time, we can try to use acid pickling method, although there will be negative effects, the effect is relatively ideal. Pipeline corrosion is usually removed by chemical and electrolytic methods. Pipeline corrosion protection only uses chemical pickling, which can remove oxide scales, rust and old coatings. Sometimes it can be used as a reprocessing after sandblasting and rust removal. Although chemical cleaning can achieve a certain degree of cleanliness and roughness of the surface, its anchor lines are shallow and easy to pollute the environment. According to the actual situation, the above rust removal schemes are selected to avoid further corrosion of cold-drawn seamless steel tubes.
