Description

TECHNICAL FIELD

[0001] The utility model relates to stainless steel pipe production manufacturing technical field, concretely relates to a pipe cleaning equipment. BACKGROUND

[0002] After the production of stainless steel pipe, the inner and outer surfaces will be contaminated by dust, oil stains and other sundries, and it is also easy to leave chemical additives used in various production and processing processes, such as lubricants and coolants. If not cleaned, it will affect the quality of subsequent electrolytic polishing treatment.

[0003] The traditional cleaning process adopts high-pressure water gun to flush the inner and outer surfaces of the pipe. This kind of cleaning method is relatively easy to handle the sundries outside the pipe, but it is difficult to clean the inner wall of the pipe. This is because when the high-pressure water gun flushing head is inserted into the pipe for flushing, it is often impossible to confirm whether the cleaning point can cover all the areas that need to be cleaned, and whether the cleaning is in place. Therefore, the cleaning process needs to be repeated, which not only consumes time and effort, but also the cleaning quality is not the same. Because it is extremely dependent on the operation proficiency of the operator, this kind of traditional cleaning method not only has low working efficiency, but also is difficult to ensure the cleaning effect, and there are many cleaning blind spots when the pipe body is long. For stainless steel pipe products with thin diameter, the high-pressure water gun used for cleaning needs to be customized with a special flushing head, which undoubtedly increases the additional economic investment in the preparation of cleaning tools.
