Underground metal pipeline at its intercrossing with automobile and railways are laid in steel cases. The following problems arise when design engineers analyze the matters of electrochemical protection (ECP). These are the possibility and expediency of protection of such a double-tube design. The method of discretization in the course of computation of arbitrary pipe installation ECP can be successfully used also for calculation of current field of double-tube designs. Later we ‘ll consider the results of numerical analysis of certain problems with steel case. ECP problems were being resolved with using new complexes of programs being distinguished from preceding ones by occurrence of module for calculation of galvanic protection of steel cases.
