Analysis of Friction Performance of Straight Plate Pig in Natural Gas Pipelines
摘要
Abstract
The pig operating condition directly affects pigging efficiency and safety.To gain an in-depth understanding of the friction performance of a straight-plate pig during operation in a natural gas pipeline,a finite element model of a straight-plate pig operating in a straight pipe is established using ANSYS finite element analysis software.The friction force during pig operation is calculated,and the effects of pipe inner diameter and friction coefficient on the maximum friction force and the steady friction force are analyzed.The results show that the friction force during pig operation exhibits pronounced stagewise variation,four"rise-fall"intervals are observed,and a stable state is ultimately reached.The friction force is reduced as the pipe inner diameter is increased;when the inner diameter is increased from 201 mm to 209 mm,the maximum friction force is reduced from 3635 N to 2766 N,and the steady friction force is reduced from 2905 N to 2331 N.The friction force is increased as the friction coefficient is increased;when the friction coefficient is increased from 0.1 to 0.5,the maximum friction force is increased from 2 108 N to 4 070 N,and the steady friction force is increased from 1 297 N to 3 551 N.An increase in the maximum friction force causes the risk of blockage at diameter-change sections to be increased,and an increase in the steady friction force causes the resistance to continuous pig operation to be increased,thereby increasing the risk of blockage during pigging operations.关键词
