由于管道运输所特有的优势,从1958年我国建成的第一条长输管道——克独输油管道工程至今,管道运输行业得到了迅速的发展,一跃成为我国继铁路、公路、航运、水运外的第五大运输业,应用的领域遍及工业、农业、国防等,与我们的生活已经密不可分。1 长输管道所具有的特点1)长输管道建设投资大、建设周期长、参与单位多、质量影响因素多,质量控制较困难。2)输送具有连续性。长输管道一旦建成投产,一般情况下为连续运行,相应地增加了不停输带压维修的操作难度和危险性。
Due to the unique advantages of pipeline transportation, from 1958, the first long-distance pipeline built in China-Ke Duo oil pipeline project so far, the pipeline transportation industry has been rapid development, has become China’s railway, road, shipping, water transport Outside the fifth largest transport industry, applied in areas such as industry, agriculture, national defense, and our lives have become inseparable. 1 Long-distance pipeline has the characteristics of 1) long-distance pipeline construction investment, long construction period, many units involved, quality factors, quality control more difficult. 2) Conveyance is continuous. Once the long-distance pipeline is completed and put into production, the continuous operation is generally carried out, which accordingly increases the difficulty and danger of operation of the belt pressure maintenance.
