Pickling is a process in the processing of stainless steel heat exchange tubes, so what is its role?
1. Remove oxide scale and welding slag
Due to production and processing, the surface of stainless steel heat exchange tubes produces oxide scale and welding slag, which affects the quality and corrosion resistance. At this time, pickling can effectively remove them and make the surface of stainless steel heat exchange tubes smoother.
2. Improve corrosion resistance
After pickling, the chromium oxide film on the surface of the stainless steel heat exchange tube can be enhanced and repaired to improve corrosion resistance.
3. Improve appearance quality
After pickling, the stainless steel heat exchange tube has a bright and uniform surface and consistent color, which is suitable for the decoration industry.
