Study of the erosion-corrosion behavior of P110, N80 and VM140 steel in 3.5wt.%NaCl solutions with sand
With the development of hydraulic fracturing technology,the failure of the equipments during production test and completion well becomes more and more severe due to the behaviors of erosion-corrosion.In this paper,the erosion-corrosion behaviors of N80,P110 and VM140 materials were investigated with the jet impingement experimental device.The corrosive rate of these materials by the weight loss method was carried out under different flow velocities and jet angles.It was observed that the weight loss of the three materials is increased by the rising of the impact velocity.The relation of erosion-corrosion weight loss to impact velocity is well described as the equation E=KVn (E is the speed,V is fluid velocity,k and n are the fitting parameters).As a results,the resistance ability for corrosion-erosion under experimental conditions is P110>N80>VM140.
