Abstract

The invention discloses a production process for a sanitary stainless steel pipe and in-pipe polishing equipment. The process and the equipment solve the problems that a sanitary stainless steel inner wall is obvious in polishing mark, fluid flowing through the stainless steel inner wall is easy to stay in the polishing mark, and the sanitary requirement is influenced. The production process includes the steps of (1) molding and welding; (2) solution annealing; (3) sizing and straightening; (4) stain removing; (5) polishing; (6) pickling; (7) passivating; (8) coating; and (9) warehousing. According to the production process for the sanitary stainless steel pipe and the in-pipe polishing equipment, the inner surface and the outer surface of the produced stainless steel pipe are each provided with three different protective films, so that the stainless steel pipe can be prevented from rusting when encountering chemical substances in the ocean climate, and electrochemical corrosion is avoided; and the inner wall of the stainless steel pipe is provided with a silver film with the nanoscale thickness, so that germs in liquid can be removed, and the sanitation level of the stainless steel pipe is improved.

Description

technical field

[0001] The invention relates to the field of manufacturing stainless steel pipes, in particular to a production process and equipment for sanitary grade stainless steel pipes. Background technique

[0002] The traditional welded pipe production line process is generally used in the production of industrial pipes with low quality requirements. As stainless steel welded pipes are used more and more widely, power generation, air conditioning, and chemical industries have also begun to use stainless steel welded pipes, but their quality requirements are high, and their surface, size, and performance requirements are higher than those of general industrial pipes. The previous process cannot meet the product requirements. quality requirements. At present, polishing the inner wall of stainless steel welded pipe is a common process. The existing internal polishing unit includes a guide rail, a power device placed on the guide rail and a pinch pipe erected on the gu...
