“…The erosion of the steel surface by a stream of solid particles has been an issue of concern for decades due to high material loss and maintenance costs [6,7]. Unfortunately, there is no universal model that can effectively predict all erosion situations [8][9][10] and development of a reliable and effective model for solid erosion process still remains a challenge. Several attempts have been made to understand the effect of different parameters, such as; temperature, particles size, and microstructure of both the impinging and eroding surfaces on the solid particles erosion process [11][12][13][14][15][16][17].…”

Abstract:Erosion is the gradual removal of material due to solid particle impingement and results in a failure of pipeline materials. In this study, a series of erosion tests were carried out to investigate the influence of particle speed and impact angle on the erosion mechanism of API X100 pipeline steel. A dry erosion machine was used as the test equipment, while the particle speed ranged from 20 to 80 m/s and impact angles of 30 • and 90 • were used as test parameters. The eroded API X100 steel surface was characterized using scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS). The weight loss and erosion rate were also investigated. The results showed that at a 90 • impact angle, a ploughing mechanism was occurring on the tested specimens, while material removal through low-angle cutting was the dominant mechanism at lower impact angles. Embedment of alumina particles on the target steel surface, micro-cutting, and low-angle cutting were observed at low impact angles. Therefore, the scratches, cuttings, and severe ploughings observed on some failed oil and gas pipelines could be attributed to the erosion mechanism.

Hertzian fracture (ring or cone cracks) are expected to occur at rather low impact velocities and lager particles [1,26], at hardness ratios (c) Magnification of individual erosion sites, illustrating lip formation, described in [15,16], and the formation of shallow lateral fractures (arrowed) between plastically deformed sections.

In studies of erosion-corrosion at materials at elevated temperatures, there have been many attempts to model the process. Such models have comprised quasi-static and simulation models. However in many environments, erosion-corrosion occurs in aqueous conditions and can be considerable affected by flowing gases in dry conditions. In such cases, any accurate models of erosion-corrosion must include an algorithm due to flow in addition to the mechanics and chemistry of the tribo-corrosion interactions. In this paper, a CFD model is generated of the tribo-chemical interaction at elevated temperatures. The initial work has concentrated on modeling temperature effects in wet conditions; however, the potential application of the model to dry conditions is also outlined. The results are discussed in relation to existing erosion-corrosion models in the literature at elevated temperatures.
