Cleaning of hydraulic pipe joints

The cleaning of hydraulic pipe joints is divided into kerosene cleaning and acid cleaning. Kerosene cleaning is mainly for copper pipes and stainless steel pipes. First, remove the pipes and joints to be cleaned. Both ends and joints are directly soaked in kerosene for cleaning. The standard after cleaning is that there should be no visible contaminants. The pickling is mainly for the heavily corroded steel pipes. First, degrease, wash with water, then remove the rust, and then neutralize it with lye. Be careful not to wash the marks on the pipes.
