沿山区伴行路、隧道和山梁敷设的管道 ,呈波浪起伏状 ,落差较大 ,由此增大了管道试压与吹扫的难度。文章以兰成渝输油管道第八标段为例 ,介绍了山区大落差管道试压与吹扫的施工经验 :试压与吹扫地段的划分。
The pipeline that laid along the companion trip road, tunnel and ridge of mountain area, submits wave to rise and fall, drop is greater, difficulty has increased for pressure examination and blow to sweep. Taking Lanchengyu 8th mark section of petroleum pipeline for example, construction experience of mountain area has been introduced such as partition of section of pressure examination and blow to sweep, location option of water up and down as well as major technical measures.
