The technology is related to the use of metal  pipes  constructed  from  several  layers  of  metal  foil  as  structural components, and the process for their manufacture. The original use of these is in nuclear fusion reactors, for which they  have  been  successfully  tested and  where  such  pipes  would  be  exposed  to  extremely  high  temperature  and  pressure regimes, far exceeding the allowable regime of application of conventional (steel)  pipes.  The  technology  is  ready  for  use  in  the  non-­‐fusion  domain  and  was  patented by the inventors Jens Reiser, Bermhard Dafferner, Anfreas Hoffmann, Michael Rieth, Werner Schulmeyer and Anton Möslang
