PRODUCTION OF A PIPE WITH A FUNCTIONAL LAYER ON A CORE AND A PIPE
For producing a pipe, a core is provided and a functional material, a fiber composite material and a shrink material forming a shrink tube are applied radially externally to the core. The pipe is thermoformed by heating of the pipe with application of radially inward pressure to the fiber composite material and radially outward pressure to the functional material, this in turn by radially inward thermal contraction of the shrink tube and/or radially outward thermal expansion of the core. At the same time consolidation of the functional material together with the fiber composite material form the pipe, and cooling to a cold temperature and demolding of the consolidated pipe from the shrink tube and from the core. The functional material has such a media resistance with respect to the medium that for a planned usage period it is less damaged by the medium than the fiber composite material.
