[origin: DE4104216A1] A pipe with an inner pipe (1) conveying the medium and an outer pipe (2) comprise a sensor (S) in the packing (3) between the pipes for detecting fault locations. In addition, data (D) are transmitted via a cable fitted to the pipe. The aim is to reduce the costs for transmitting the data (D). According to the invention, the sensor (S) is also used to transmit the data (D). Especially for a pipe for conveying liquid media for remote heating.
