Analysis on Erosion Wear Laws of High Pressure Manifold

In view of the problem that the inner wall of the high-pressure manifold is damaged by erosion during the fracturing operation, the erosive wear rate and the erosion dispersion distribution of the inner wall of the high-pressure manifold are studied using FLUENT software based on the solid-liquid two-phase flow and the erosive wear theory. The influence of the bend curvature radius, bend curvature and the inner diameter of the high-pressure manifold on the erosive wear of the manifold were analyzed. The results show that the erosive wear is the most serious at the outlet of the bend of the high-pressure manifold. The discrete distribution is concentrated at the bend to the outlet of the straight pipe. The erosion wear rate in the straight pipe is very small. With the increase of the inner diameter, the curvature radius of the bend and the bend curvature, the maximum and the average erosion wear rate of the manifold decrease. With the increase of the inlet flow velocity, the maximum and the average erosion wear rate increases. The results can provide references for the failure, failure prevention and protection of high-pressure manifold.
