51317--9637-Non-Metallic Liners for Dense Slurry (Oil Sands) Applications

 This paper summarizes the experimental findings, discusses the effects of a typical bitumen-water slurry solution on the wear performance of polyurethanes and neoprenes and proposes a mathematical relationship between Coriolis (low stress, low angle abrasion & scouring) wear to the relevant physical properties in the virgin state of polyurethanes and neoprenes.

Non-metallic liners such as polyurethane and neoprene are currently extensively used in oil sands operations in Canada to protect the dense slurry pipeline. Not only do these liners provide corrosion-protection from the aqueous slurry these also offer very good wear performance comparable to if not better than metallic pipeline materials. However there is limited information available in the industry on what physical properties of non-metallic liners impart improved wear performance. The effects of water and hydrocarbon (bitumen) in the oil sands slurry on the wear performance of the non-metallic liners are also unknown. Shell Wear Technology Team had recently conducted the comprehensive immersion testing of at least 9 polyurethane and neoprene liner materials in the bitumen slurry and investigated the changes in the physical properties (i.e. hardness rebound resilience scratch resilience etc) and the wear performance (i.e. Slurry Jet Erosion Coriolis wear test scratch test etc) at a varying pressure and immersion time. This paper summarized the experimental findings and concluded with an empirical relationship of wear rate against the relevant physical properties both in the virgin and after-immersion states.
