“…In the present work, erosion wear on the different piping materials has been investigated with and without coating to study the influence of three different parameters, namely, the speed of rotation, solid concentration, and test duration. The values of exponent "a" have been determined as 2.06, 1.53, and 1.69 for mild steel, SS202, and SS304, respectively, which shows good agreement with researchers [2,15]. Truscott [18] reported that value of the velocity exponent lies between 1 and 3.5.…”

“…The erosion wear experiments were performed at four different time durations: 90, 120, 150 and 180 min, at a rotational speed of 600 rpm and solid concentration of 30 wt %, which is shown in Figure 5c. The erosion wear of different piping materials, namely, mild steel, SS202, and SS304, increases with time variation for coated and uncoated steels [15]. It has been concluded from the above results that, with the increase in time duration, the erosion wear of mild steel, SS202, and SS304 increases by 36.26%, 28.11% and 30.40%, respectively.…”

“…However, the roughness of SS202 was increased approximately three times with the deposition of WC-10Co4Cr coating powder. Many researchers have found that rotational speed, solid concentration and particle size distribution are some of the major factors that influence the erosion wear rate [4,15,16]. The following empirical correlation has been used to predict the erosion wear by using experimental data, and has also been discussed [15].…”

Abstract:In the present work, erosion wear due to slurry mixture flow has been investigated using a slurry erosion pot tester. Erosion tests are conducted on three different slurry pipe materials, namely, mild steel, SS202, and SS304, to establish the influence of rotational speed, concentration, and time period. In order to increase erosion wear resistance, a high-velocity oxy-fuel (HVOF) coating technique is used to deposit a WC-10 Co 4 Cr coating on the surface of all piping materials. Experimental results show that rotational speed is a highly-influencing parameter for the erosion wear rate as compared to solid concentration, time duration, and weighted mean diameter. WC-10 Co 4 Cr HVOF coating improved the erosion resistance of piping materials up to 3.5 times. From experimental data, the exponents of solid concentration, velocity, and the size of particles are calculated for the empirical erosion wear equation. A functional equation of the erosion wear rate is developed. The predicted erosion wear is in agreement with the experimental data and found to be within a deviation of ±12%.

Characterization of the hydrodynamics within a toroid wear tester

et al. 2021

View full text Add to dashboard Cite

The toroid wear tester (TWT) is a lab‐scale device used for the assessment of slurry erosion in pipelines. Historically, its application has been limited to the relative ranking of material performance under different slurry flow conditions; however, recent studies have indicated that TWT tests could be predictive and directly applied to slurry pipeline design—provided that the flow inside a TWT is better characterized. In the present study, air‐liquid multiphase flow inside the TWT was investigated. Torque measurements were taken to characterize friction loss for different air‐liquid combinations. A visualization experiment was also conducted to evaluate flow patterns within the TWT. In the experiment, the displacements of spherical glass beads were used to estimate velocity vector fields for different TWT rotational speeds. A computational fluid dynamics (CFD) analysis was also conducted to complement the experimental measurements. A 3D transient analysis using the volume of fluid (VOF) approach was used to model the system. The simulation results agreed closely with the experimental findings. Furthermore, the simulations revealed that strong secondary flows (back flow, rotation) exist in the TWT. These type of flows do not occur in horizontal pipelines. Therefore, to use the TWT as a tool for slurry pipeline wear assessment, the differences in the flow field between the two systems must be properly quantified.
