FIELD: building industry, namely erection and exploitation of pipelines in gas and oil production, chemical industry branches. SUBSTANCE: in system for protecting pipelines against corrosion pipeline is used as controlled object. System includes two - eight separate control lines; each line is provided with pickup for detecting corrosion rate including corrosion sensing transducer and circuit for connecting pickup signals. Each line also is provided with actuating apparatus for introducing inhibitor having metering device and circuit for supplying signals of metering device. Microcontroller is connected to each line of system; said microcontroller is connected with computer base apparatus for controlling, processing and storing information through radio-relay communication device. EFFECT: enhanced degree of protecting pipeline against corrosion. 3 dwg
