To ensure the smooth and safe gas transmission pipeline, pipe used also put forward some high requirements. In order to remove the rust and steel surface oxide skin and improving the adhesion and coating on the surface, often need for special antirust, derusting processing. For corrosion heavier solid metal paint, surface treatment, use monly, cannot achieve clear standard, to achieve a specific standards, often need to adopt the way into derusting, surface derusting, for good quality of the durability of the enormous influence after coating, can make the coating are more durable number four times after treatment, shot from the metal surface, although the micro is still uneven, but the appropriate to the coating is concave and convex, because it helps the flow and adornment, make the metal surface and coating has very good adhesion of the paint, particularly effective, need more shot blasting processing, metal surface strengthening function on metal surface derusting, coating quality of life around 50% influence, derusting, more use manual work, steel wire brush, sand paper burnish, etc, these methods not only the efficiency is low, the quality is poor, the labor intensity, and environmental pollution and harm to human health, used in place of blasting, often USES a open shot room or directly open shot blasting room not only establish high cost, structure still exists, plexity of open shot unavoidable disadvantages, severe environmental pollution and harm to human health. Currently most using metal pipe wall derusting chemical pickling method,not only the cost is high, quality derusting unstable, and pollution is serious, the production of operators, unfortunately bad health hazard. Also can form rust corrosion protective coating for surface roughness, thus affecting the coating quality, reduce the pipeline using surface sanding derusting process is believed to be the best alternative pickling derusting, especially used in metal sheet metal structure and appearance of coaring, rust, and good effect has been widely used. Cleaning is the most effective before coating surface cleaning method. Again good coating, it is impossible to firmly adhere to the surface, in dirty cleaning not clean before coating, coating failure caused by means of cost, the original coating, coating, all losses, costs, corrosion, except for repairing suffer loss, cease, still need to rejoin the manpower and material resources to painting. This method of pipe length and diameter are wider range of adaptability, productivity high, cleaning effect is good, and the worker labor conditions improved greatly reduce labor intensity, and increased primer, improve adhesion to steel corrosion and corrosion resistance, extend the ability of the pipeline. Use abrators after cleaning the surface of steel has certain anchor grain depth, thus increasing the adhesion of the paint, improve the corrosion resistance of steel and corrosion resistant capability and prolong the life of pipeline. Cleaning is refers to the use of mechanical centrifugal cast to accelerating projectile after cleaning process of workpiece. On the inner surface of tube cleaning shot peening technol
