The present disclosure relates to a system having an inner structure, wherein the inner structure comprises at least one inner tube made of stainless steel and at least one sensor device with at least one sensor to measure at least one condition of the system. Under an aspect of the present disclosure a system of this type is suggested, wherein the inner structure is coated with at least one layer of at least one plastic material.

Downhole tubing or umbilical with sensor and method for manufacturing it

A flat pack () for operating a downhole tool or sensor includes a plurality of tubes (); a spacer () disposed between the tubes (); and a jacket () encapsulating the tubes () and the spacer (). The tubes () and the spacer () are positioned in the jacket () in a side-by-side arrangement. The tubes () and the spacer () are not twisted along the flat pack ().

Method for manufacturing a tube of metal in which sensors are attached to tubes, which register and signal a damage of the tube. It is detrimental that protection of the sensors at these tubes against environmental influences is complex. In contrast, it is an object of the present disclosure to provide a method for manufacturing a tube, in which the signal line can be protectively mounted. To solve this object, a method for manufacturing a tube of metal is suggested with an outer tube and an inner tube, wherein a groove is drawn in an inner surface of the outer tube or in an outer surface of the inner tube and subsequently the inner tube and the outer tube are drawn together through a drawing die, wherein the inner dimension of the outer tube is reduced such that after the drawing the outer tube is force-fitted onto the inner tube.
