摘要
本文通过对威成、威内、沪威三条管线外壁腐蚀状况及土壤腐蚀试验结果分析，表明使用２０年以上的石油沥青防护层性能基本良好，金属受到有效的保护，是埋地管道可靠的防腐蚀绝缘材料。
Analyzing test results of soil corrosion and corrosion status of external wall of Wei Cheng, WeiNei and Luwei gas pipelines, it is indicated that over 20 years petroleum asphalt coating keeps still better performance, pipe metal has been efficiently protected, and petroleum asphalt is a reliable anticorrosive insulating material for buried pipeline.
