我国目前的长输管道一般都采用埋地铺设,管道理好后覆土填平,既不破坏沿程的天然地形,也不影响农业生产,但在地下水位较高的地区应考虑水位,管道应避免处于冬夏季节水位线变化的范围内。 旧胜利线是我国第一条大口径长距离输油管道,建成投产于1965年,全长72km,与建成于1g76年的第二条含硫油线均用石油沥青玻璃纤维布作外防腐蚀层。旧胜利线在齐鲁石化30万乙烯工程供油管道建成后停 At present, the long-distance pipelines in China are generally buried. If the pipelines are properly laid and covered with soil, the natural terrain along the route will not be damaged or the agricultural production will be affected. However, the water level should be considered in areas with a high groundwater level. Avoid the water level in winter and summer changes in the range. The old victory line is China’s first large-caliber long-distance pipeline, completed and put into production in 1965, a total length of 72km, and completed in 1g76 years of the second light oil and alkali-resistant fiber glass fibers reported .
