Within the framework of the preceding BMBF project "Resource-efficient fibre-coated steel pipes for ultra-high-temperature steam applications", basic concepts and procedures for reinforcing superheated steam pipes with ceramic composite materials (CMC) were developed. It could be proven that the creep deformation of steel hot steam pipes under supercritical conditions is effectively hindered by the ceramic reinforcement. The feasibility of an on-site reinforcement of power plant pipes was demonstrated by a field test in the "Großkraftwerk Mannheim".
The reinforcement of an entire power plant pipeline comes with challenges such as having to reinforce preexisting pipe geometry (vast length of the pipelines, pipe curvature, variable pipe cross-section, outlets) as well as the quality of the reinforcement. The objective of the joint project is to develop the prerequisites for the technical implementation of CMC reinforcements in the power plant sector.
