GRAPHITIZATION OF CAST IRON AS AN ELECTROBIOCHEMICAL PROCESS IN ANAEROBIC SOILS

Topics include Review of the literature description of the phenomenon of corrosion of cast iron in the ground sulfate reduction and its occurrence in nature consideration of the possibility that hydrogen sulfide from sulfate reduction is the cause of iron graphitization significance of sulfate reduction in the process of iron corrosion in the ground chemistry of the anaerobic iron-corrosion process with sulfate reduction process of iron corrosion with sulfate reduction in the laboratory is the same as anaerobic iron corrosion in the ground iron corrosion processes encountered in waterline practice, considered from the electrochemical point of view, do not differ essentially from each other concept of aggressiveness of soils discussion of pipe material and its protection in connection with soil aggressiveness.
