The equipment must be cleared of rust before it is put into service. The thoroughly cleaned surfaces shall be inspected for iron and / or water tests.
  2. we also need to regularly clean up the surface of the ductile iron cover dust. Steel castings are often made on dusty grounds, often with a lot of dust in the air, which constantly falls on the surface of the equipment. They can be removed with water or alkaline solution. However, grime with adhesion needs high-pressure water or steam for cleaning.
