A kind of stainless steel pipe surface treatment process

Abstract

The invention discloses a surface treatment process for stainless steel tubes, which belongs to the field of stainless steel tube treatment processes. It is a surface treatment process for stainless steel tubes. In this solution, treatment balls are mixed into the sprayed pickling solution, and the liquid storage on the surface of the egg-shaped spherical shell is used. The tube stores the pickling solution. During the process of spraying the pickling solution, the treatment balls will be sprayed out together. After the treatment ball contacts and produces impact and breaks, it adheres to the inner wall of the pipe to be treated under the action of the surface tension of the pickling solution. After that, under the action of the air bag, the three-dimensional space structure formed by the liquid storage tube collapses, and the pickling solution is released for pickling infiltration. Finally, the transmission roller is rotated, and the inner wall of the pipe to be treated is cleaned by the liquid storage tube, and the pickling liquid is removed. The sundries are peeled off from the inner wall of the pipe to be treated, which can greatly increase the success rate of stainless steel surface treatment, is less prone to uneven pickling, and improves the performance of subsequent processing of stainless steel pipes.

Description

technical field [0001] The invention relates to the field of stainless steel pipe treatment technology, more specifically, relates to a stainless steel pipe surface treatment technology. Background technique [0002] Stainless steel has excellent characteristics such as unique strength, high wear resistance, superior anti-corrosion performance and not easy to rust. Therefore, it is widely used in industry, food machinery, electromechanical industry, household appliance industry and home decoration and fine decoration industry. The application and development prospects of stainless steel will become wider and wider, but the application and development of stainless steel largely depends on the development of its surface treatment technology. [0003] The surface treatment process of stainless steel is usually to endow stainless steel with some new functions, such as pickling and phosphating treatment of stainless steel, which will greatly increase the surface properties of st...

AI Technical Summary

Problems solved by technology

[0004] In the existing stainless steel pickling and phosphating treatment methods, the pickling method mainly includes soaking in the pickling pool and using a high-pressure nozzle to spray the pickling solution to the position to be treated. Among them, the high-pressure nozzle spraying method can greatly reduce the consumption of pickling solution It is a relatively environmentally friendly method to reduce the amount of waste water in the pickling process and soak in the pickling tank. However, for the inner wall of stainless steel pipes, it is difficult for technicians to use high-pressure nozzles to fully and evenly pickle the inner wall of stainless steel pipes. , especially the sprayed pickling solution will slide from the inner wall of the stainless steel to the bottom due to its own weight, and accumulate, which will easily cause excessive corrosion at the bottom of the stainless steel, making the surface treatment of the stainless steel fail
