天然气集气站气质成分复杂，管道密集且敷设方式多样，导致站内管道元件存在腐蚀减薄、腐蚀穿孔泄漏等安全隐患。根据集气站内管道元件的实际腐蚀案例，对天然气集气站管道元件腐蚀机理、腐蚀位置预测技术展开了研究,提出了一套有效的内腐蚀位置预测技术。

In natural gas gathering stations, the composition of natural gas is complex and the pipeline laying is intensive and diverse, which can cause the securisly risks of corrosion thinning and corrosion perforation leak of the pipeline component. In regard to the internal corrosion problem of pipeline component, to probe an effective corrosion location forecasting technique is of important significance in research and engineering. According to the actual corrosion cases of the pipeline component, the corrosion mechanism and location prediction of pipeline component in a natural gas gathering station were studied, and a prediction methid was presented.
