摘要: A pipe or fitting having a polymer liner and a replaceable component including an outer ring having an outside diameter matching the inside diameter of the pipe or fitting, a polymer liner bonded to the outer ring and having an inside diameter matching the inside diameter of the liner of the pipe or fitting. The replaceable component is disposed in an inlet or outlet of the pipe or fitting so as to form a continuous bore lined with a polymer.

摘要: A method for extracting bitumen from an oil sand slurry involves limiting the size of rock and clay lumps in the slurry to a first size, conditioning the slurry in a pipeline, screening the slurry through a rotary screening apparatus to remove the lumps that are larger than a second size, and subjecting the slurry to gravity separation to separate the bitumen as a bitumen froth. A fastener assembly for securing a screen panel to a drum shell of a rotary screening apparatus includes an outer insert for insertion into an aperture of a drum shell, an inner insert for insertion through an aperture of the screen panel and into an inward facing pocket of the outer insert, and a bolt for securing together the outer and inner inserts. An insert for removable insertion into an aperture of a drum of a rotary screening apparatus defines a screening aperture.

摘要: A process for operating a settling slurry transportation pipeline is provided, comprising: determining the deposition velocity for a particular slurry being transported through the pipeline; and operating the pipeline at an operating velocity at or near the deposition velocity to form a stationary or near stationary bed of solids that will still allow the slurry to freely flow through the pipeline and not plug the pipeline.
