Circulation Pickling

For KOPSCHINA, pickling of already installed plants or entire piping systems does not represent a problem either. During the circulation pickling process, we connect your plant with pipes or flexible chemical feed pipe to form a closed system. Acid-resistant filter pumps ensure that the liquid pickling medium used circulates through the piping system – and therefore through your plant. As soon as the desired degree of pickling is achieved, we will rinse the pipe system using suitable water. Thus, the residues of the pickling medium and detached impurities will be removed from your plant. Circulation pickling can take place both in our works and at your company sites by means of a mobile pump circuit. The pickling chemicals used by KOPSCHINA contain special inhibitors which ensure that the chemical removes only such an amount of material as is required to achieve the desired result. Thus, we spare both the environment and material!
