Abstract

Geometric analysis of the flow path in pipeline gate and ball valves permits identification of the zone where the abrasive pollutant flux is most intense. The speed of this flux contributes greatly to its aggressiveness. Recommendations are made for more effective protection of the moving parts in shutoff valves.

改善了石油和天然气管道中IGR截止阀的耐磨性

摘要

通过对管道闸阀和球阀中流路的几何分析，可以识别出磨料污染物通量最大的区域。助焊剂的速度对其侵略性有很大贡献。提出了一些建议，以更有效地保护截止阀中的活动部件。
