Description

Technical Field

[0001] The invention relates to the technical field of pipe processing, in particular to a processing system for manufacturing stainless steel pipes of heat exchangers. Background Art

[0002] A heat exchanger is a device used to transfer heat between two or more fluids. It is widely used in industrial processes, HVAC systems, refrigeration, chemicals, power and other industries. The heat exchanger includes a shell, heat exchange pipes, support structures, seals and control devices, of which the heat exchange pipes are the most important part. The heat exchange pipes are usually made of stainless steel sheets rolled and welded. However, during the rolling process, the following problems exist:

[0003] 1. In the process of rolling stainless steel plates into heat exchange pipes, it is usually necessary to spray graphene materials inside the pipes to form an anti-corrosion protective layer. In order to ensure the spraying effect and welding effect of the protective layer, the inner and outer walls of the stainless steel plates need to be cleaned. When cleaning, a fixed cleaning non-woven fabric is usually used to clean the plates. At the beginning of cleaning, the cleaning effect is good, but as the cleaning process continues, a large amount of dust and impurities adhere to the surface of the cleaning non-woven fabric, and the cleaning effect decreases, resulting in uneven cleaning effects before and after. In addition, the cleaning method is single. Before spraying, impurities and stubborn stains that fall into the stainless steel pipe during the rolling process cannot be removed, thereby reducing the spraying effect.

[0004] 2. The internal spraying of stainless steel pipes is carried out after the plate is rolled into a U shape. Usually, when the pipe is conveyed forward along the processing system, a fixed nozzle is used to spray the inside of the stainless steel pipe at a fixed angle. Usually, the bottom of the U-shaped pipe has a good adhesion effect after spraying, while the side wall of the U-shaped pipe has a poor adhesion effect after spraying, and uneven spraying is prone to occur.
