Coefficient for speeding pipeline system abrasion and abrasion prediction

Sand erosion can abrade corrosion protection film on pipe wall and brings about serious abrasive corrosion.This kind of corrosion will be affected by many factors.Approaches how these factors act in combination with each other to bring about abrasive corrosion.B.S.Mclaurry and so on combine abrasive experiment and flow model (including sand abrasion) into research process.This method includes a research on such factors as the effect of sand abrasion and abrasive corrosion on pipe wall thickness losses, which covers : pipeline geometric shape, size, pipe material, flow rate, fluid viscosity an density, sand grain's size, shape, density and sand production rate.Puts forward a method for predicting sand abrasion speed.The method is developed on the basis of an experience suitable for sand abrasive condition used early in previous.Compares prediction result of abrasive corrosion with experimental data.
