1.Chemically clean and treat internal surfaces of hydraulic lines.
2.Perform hot oil flushing to reach target cleanliness level.
3.Inspect and verify that the cleanliness level has been achieved.
4.Follow the proper steps when disassembling the flushing loops to prevent contaminants from re–entering the cleaned system. Seal off all openings with plugs, blind flanges and Plastic sheets.
The object for acid carrying out cleaning of Hydraulic Pipelines is to remove mill scale, oil, paint, preservatives, rust, welding slag that would have entered during assembly of new tubes and also to remove the oxides of iron. After carrying out the process, the internal surface of the system is passivated by means of protective layer to prevent further rusting and corrosion.
