The detailed engineering followed within six weeks of the preplanning.

conduct, procurement of the components and turnkey installation of the FRP connecting pipes.

Together with Alstom and the plant operator, Fiberpipe defined the job specification as well as the pipe direction. All aspects of the pipe assembly were grouped together in a quality assurance concept followed by an acceptance procedure. The detailed engineering was carried out by Fiberpipe, including stress analysis, three dimensional tube

The assembly propositions took into consideration the knowledge of which resins are resistant to high temperatures, pressure, insulation, heat loss, chemical resistance and surface temperature. The fibreglass components came with a 2.5mm thick chemical barrier, ensuring optimum reliability. All components were prefabricated by Fiberpipe, and

the laborious reconstruction was shortened, resulting in a planned factory downtime of only 48 hours.

Pressure resistant pipe and fast assembling: capacity increase in waste incineration Enertec, Germany, is a power plant site with waste incineration, biomass gen- eration and long-distance heating supply. Each year the site recycles 240,000t waste, as well as 120,000t biomass generating 110m kWh electricity and 240m kWh long-distance heating. In linewithacapacity increase, the cooling water circuit of the power plant needed to be replaced within six weeks, and the company wanted to introduce FRP pipelines. An external service provider was entrusted with the planning of the capacity increase; because of an existing collaboration with Enertec, Fiberpipe was the first point of contact for the pipeline construction. Together with all participants, a detailed test and acceptance procedure was created.
