Stainless steel pipe is a hollow long steel material, which is widely used as a pipe for transporting fluids such as oil, natural gas, water, gas, steam, etc., and is also widely used for manufacturing machine parts and engineering structures because it is light in weight while having the same bending and torsional strength. And are also commonly used to produce various conventional weapons, barrels, projectiles, and the like. After the steel pipe is rolled or drawn and produced, some impurities such as stains, impurities, oil and the like are remained on the outer wall of the steel pipe, if the impurities and the like are not cleaned, the outer wall of the steel pipe is corroded, the steel pipe is easily damaged, the quality of the steel pipe is reduced, the service life of the steel pipe is shortened, and therefore the cleaning of the outer wall of the steel pipe is indispensable and very important.

At present, the method for pickling the steel pipe is used for cleaning the outer wall of the steel pipe in China, and the specific cleaning process is as follows: the steel pipe is introduced into an acid pickling bath, and oil stains attached to the steel pipe are removed by nitric acid, hydrofluoric acid or other similar acid solution with the concentration (mass percentage concentration) of about 30-45%. Although the method can remove the oil stains on the surface of the steel pipe, the method has the following defects: firstly, when the steel pipe is introduced into a pickling tank for cleaning, the pickling solution can damage the limbs of operators, so that great potential safety hazard exists; secondly, the working efficiency is low and the labor intensity of workers is high by adopting a manual operation mode; thirdly, the method is not beneficial to environmental protection, because the pickling waste liquid pollutes a water system, soil and air if the pickling waste liquid cannot be effectively treated; fourthly, the pickling is performed by chemical cleaning instead of physical cleaning, so that the influence of chemical corrosion on the steel pipe body exists; and fifthly, the construction of the pickling bath is needed, so that the investment cost is high, and the pickling bath is easily limited by objective conditions, for example, under the condition that the site is not abundant, the pickling bath cannot be built in a precaution manner.
