Abstract
The invention is concerned with a process for transporting a thermally unstable viscous mass through a pipe having a predetermined breaking point to release excess pressure, which predetermined breaking point breaks when the excess pressure is reached, the excess pressure thus being released, and is characterized in that the predetermined breaking point is provided in the interior of the pipe, provided that the predetermined breaking point is not provided as a portion of the inner wall of the pipe.
