Experimental Investigation of Erosive Wear of Steel For Liquid-Solid Flow

Abstract

Erosion is the degradation of the flow carrying devices used in hydrocarbon and mineral process industries, especially those involved with solid particle transportation at high conveying velocities, such as many onshore and offshore oil and refinery industries. Slurry erosion has been a major concern for many recent types of research, steel is being extensively used in pipelines for long-distance transportation of slurry products. This widespread use of pipelines demands continuous monitoring and diagnosis of the pipeline material. Considering the problem, the purpose is to examine the impact conditions, material properties, and flow conditions of the selected steel material to govern the slurry erosion resistance. Many attempts have been done to reduce the damage, but considering the complexity of slurry transportation still, a lot of work has to do because erosion becomes worse in slurry transportation due to the presence of large solid particles. The rate of slurry erosion caused by smaller particles is enhanced by large particles as more kinetic energy imposes on the material’s surface, resulting in greater material removal impact. Power plants and refinery industries are the main pillars of many countries’ economies, so an inexpensive and optimum method to have a proper checkup of transportation pipelines is very important to the understood relationship between microstructures and wear resistance of carbon steel in case of slurry erosion
