Abstract

Disclosed are a method and a device usable in said method for verifying the casing (4) of a pipeline (3). According to the invention, the pipeline (3) is inserted into the liquid-filled borehole (6) by means of an electrically non-conductive pulling head (2), whereby a measuring apparatus (5) can verify, when the pipeline is laid, whether the casing (4) of the pipeline (3) is not damaged.
