摘要：
The erosion rates (expressed as grams per square millimeter per minute) of three casing steels (P110, N80 and K55) and hot-rolled 1020 steel in quartz sand-oil suspensions, GFN 140, solids loading 0.5-4 wt.%, at speeds from 9.35 to 18.7 m s-1 have been measured in a slurry pot tester. The velocity exponent was determined as 2.4 and the relationship of erosion rate to solids loading and particle size (for the particle size range 53-180-mu-m) determined. The erosion rates for all the steels were found to lie within a scatter band of +/- 15% and could not be related predictively with the measured tensile properties. Results are discussed in terms of the rate of particle impact on the eroding target and the need to control flow conditions through appropriate design to minimize erosion.
