In the present paper an innovative piping system was described for the hydro-transport of wear-intensive slurry, such as those found in the processing of oil sands resources. Pipes are composed of an external load-bearing fiber-reinforced polymer pipe and an internal erosion/corrosion resistant polyurethane liner. It was shown that such structure can be produced by appropriately pre-curing the liner material and subsequent overwrapping the liner with a fiber-reinforced thermoset resin system. Co-curing of liner and structural pipe is used to create a chemical bond between the two constituents. This is important to prevent liner collapse failure. A commissioning procedure producing a defined network of cracks in the resin matrix of the structural pipe will further mitigate the risk of liner collapse by allowing for venting of volatile species to the atmosphere. The fabrication procedure for pipe specimens was presented, including a suitable joining technique. In addition, the authors elaborated on solutions for manufacturing of large-scale structures. Lastly, future work items that need to be addressed prior to development of prototype structures were discussed.
