ABSTRACT

Multiphase twin screw pumps are used by the oil and gas production industry to boost the transport of hydrocarbons allowing for a greater field recovery and longer transport distances. The pumps are subjected to wear due to corrosion, erosion and erosioncorrosion. This paper presents testing equipment that allows for a classification of materials regarding to their wear resistance in multiphase environments. It will be shown how parameters such as the flow velocities, temperature, electrochemical potentials and different oil/water cuts can be investigated and how different materials perform under these conditions. The main objective of the paper is to illustrate, how materials can be optimized for a specific multiphase application in order to increase component lifetimes and maximize production by minimizing maintenance.
