ANTI-CORROSION METHODS OF OIL-STOLEN ORIFICE IN UNDERGROUND OIL-PIPELINE

Several anti-corrosion methods of oil-stolen orifice in underground oil-pipeline are introduced.The advantages and disadvantages of different anti-corrosion methods as well as their adaptability are analyzed.Based on experiments of shear strength of anti-corrosion layer with different surface conditions,the data of shear strength and the influence of surface pretreatment conditions on the performance of anti-corrosion layer have been obtained.The results of the research can provide guidance for field operation.
