First of all food grade stainless steel pipe piping inner wall should be polished. The higher the Ra value of the inner wall, the more favorable to the later cleaning process. For the cleaning and disinfection of the pipeline, I personally believe that first of all, you can use a weak alkali or weak acidic solution rinse or soak in the use of high temperature and high pressure water flushing. You can also add flexible particles in the high-temperature and high-pressure water to rinse the pipe wall, and then rinse in high-temperature pure water.
