Pipeline utilizing thick-matter pump for determining a pressure and/or a wall thickness simply, durably and reliably

A pipeline for delivery of thick matter, comprising:

• a first longitudinal section of the pipeline with a first wall thickness;
• a second longitudinal section of the pipeline with a second wall thickness which is greater than the first wall thickness;
• a first strain gauge on an outer side of the first longitudinal section;
• a second strain gauge on an outer side of the second longitudinal section, wherein
• the strain gauges are attached in each case fixedly on the longitudinal sections or are attached on outer sides of the longitudinal sections, and
• the strain gauges are used for determining a pressure in the pipeline and/or a wall thickness of the pipeline, wherein
• the first strain gauge and the second strain gauge are elongate, and their length is greater than their width, and
• the two strain gauges are attached with the same orientation on the pipeline with an extent in accordance with their longitudinal direction along the longitudinal direction of the pipeline.

• the pipeline has a pipe with a continuously constant first wall thickness which forms the first longitudinal section, and
• an outer pipe is placed onto the pipe as a cuff with a wall thickness in accordance with the difference between the first wall thickness and the second wall thickness to form the second longitudinal section.
