A double-wall pipe for a transportation means which includes an outer pipe and an inner pipe extending therein. The outer pipe has two pipe segments which are formed like half-shells and are joined together to form the outer pipe along the longitudinal edges thereof. In this way, it is possible to make both the outer pipe and the inner pipe of metal, such that the wall thickness of the inner pipe can be relatively small.

Double-wall pipe and production process

Sensor structure of a flow body protruding into a current for carrying out measurements of flow states, containing a structural part () with at least two measuring orifices (), to which transfer lines () are coupled, which guide the flow medium from the measuring orifices () to a pressure converter system () for the purpose of determining the flow states. The outer shell () of the structural part () contains two areas (), which are arranged behind each other viewed in the direction of flow, wherein the first area () has greater thermal conductivity than the second area (). Within the first area () heating elements () are arranged on the structural part (), and are connected with a temperature control circuit with the temperature on the surface of the first area () as a control variable.
