油气长输管道作为保证长距离成品油运输的关键要素,沿途不仅路程漫长而且所经地区环境复杂,既有可能对管线造成侵蚀(比如风沙、雨雪)也有可能因为油气管线的质量控制不佳而对管线沿途生态造成威胁。文章从长输管道穿越工程对管道本身的材质、施工要求、线路选择等方面深入,论述了对油气长输管道穿越工程的质量控制问题。 Long-distance oil and gas pipelines as a key element to ensure the transportation of long-distance oil products are not only long distances along the route, but also complex in the region. Erosion of the pipeline (such as wind and sand, rain and snow) may also occur due to the poor quality control of oil and gas pipelines The pipeline along the way of ecological threats. The article discusses the quality control of long-distance pipeline crossing project from long distance pipeline crossing project to the pipe material, construction requirements, line selection and other aspects.
