The article is devoted to the study of the corrosion process rate of steel parts in livestock and poultry buildings, primarily, dung removers, which are operated and exposed to a chemically aggressive environment. The issues of metal loss of parts which are in contact with waste products of cattle, pigs and poultry are considered. The results of the influence of corrosion processes on loosening torque increase of the threaded joints of dung removing equipment for livestock and poultry farms are also presented. The research results can be used in design and repairs of farm dung removers.
