For the choice of cathodic protection potentials of strenuously-strain underground pipe-lines, it is necessary additionally to determine the current density of cathodic protection and compare it with limiting current density by oxygen under real conditions of pipelining. This permits to exclude or minimize the formation of corrosion defects.
