Abstract

Procedure for detecting leaks in pipelines for fluid media, having an inner tube (2) carrying the medium, an outer tube (3) surrounding the inner tube (2) and a reinforcement of filling material (4) in the annular space between the two tubes, in which procedure the filling material (4) is provided with a definable electric conductivity, as a result of which the nature of a point of persistent defects (S) is determined by measuring the ohmic resistance of the filling material (4) at the beginning and end of the tube (1), to earth in each case, as well as between the beginning and end of the tube (1), and determining the location by methods of cable testing technology. <IMAGE>
