Benefit of structured surfaces
The operating principle and associated performance of several types of structured surfaces are presented in Chapter 1.
Manufacturing of a structured surface inside a tube section
This section mainly deals with the manufacturing of structured surfaces inside tube sections during the application of an internal coating that is at the coating applicator workshop. The embodiment presented consists in the use of a flexible element provided externally with structured surfaces whose image is mirror to that which should be produced on the internal coating.
This section will be completed later
