| dc.description | One major drawback of carbon steels and API X-series steels is their susceptibility to erosion degradation. The co-existence of three phases: carrier liquid (oil), hard solid particles (abrasive particles) and material surface (pipeline inner surface) are responsible for slurry erosion in pipelines. Despite pipelines good safety record, this complex mode of failure reduces the pipe wall thickness and shortens the life span of pipelines. This causes irreversible damage to life and environment. It also causes damage to power plants, heater drain pipings, feedwater lines, etc. In order to mitigate slurry erosion in practice, a fundamental understanding of the erosion behavior of carbon and low alloy steels is necessary to develop strategies for combating degradation and prolonging the life of the steel pipe. However, slurry erosion mechanism is a complex phenomenon and is not well understood. Furthermore, erosion mechanisms are greatly influenced by several environmental factors. Studying a single variable even in a laboratory scale is a challenging task as all these factors are closely intertwined. The present study examines the slurry erosion behavior of AISI 1018, AISI 1080, API X42, API X70, API X80, API X100 and API X120 steels under different environmental conditions. The research provides a comprehensive and a systematic investigation on the effect of slurry velocity and slurry concentration on erosion behavior of steel. In addition, the study also correlates the erosion response to the steel microstructure. This information provides engineers and designers with the necessary data to make appropriate material selection decisions under different operating conditions. | en_US |
| dc.description.abstract | Slurry erosion is a destructive process encountered in oil and gas transmission pipelines. During transportation, the inner surface of pipelines are exposed to flowing abrasive liquid which causes slurry erosion. Complex mechanism and progressive nature of this problem create augmented challenges to pipeline economy and operation. Oil and gas industries spend millions of dollars to deal with the problems caused by wet erosion. Material integrity and degradation rate are key factors in the long-term performance of oil and gas pipeline networks. This research focuses on understanding the degradation processes of pipeline steels caused by the slurry erosion. The effects of slurry velocity and abrasive concentrations on erosion rate and mechanisms are identified and discussed in details. The present research also correlates the slurry erosion response of steel to its microstructure. | en_US |
