| Abstract: | With increasing acid value of the crude oil delivered by Lu-Ning Long-distance Pipline,the pumps for the 2nd and 3rd side-draws of vacuum distillation unit experienced increasingly esvere corrosion in the strong naphthenic acid corrosion environment and had to be shutdown because of the severe corrosion.The application of 1Cr18Bi9Ti and 316 steels is suggested. |
