克拉玛依—独山子输油管线是我国第一条长距离输油管线。于1958年、1959年、1960年先后平行铺三条管线。建设初期由于没有经验,也没有足够的重视,投产后十一个月就发生腐蚀穿孔。自1963年管线大修后,全线相继采用阴极保护技术,至今已二十年没有发生过腐蚀穿孔。腐蚀率由原来的257密耳/年下降至1.7密耳/年。为了及时总结 Karamay - Dushanzi oil pipeline is China’s first long-distance pipeline. In 1958, 1959, 1960 has paved three pipelines in parallel. In the early stage of construction, due to lack of experience and inadequate attention, corrosion and perforation occurred 11 months after putting into production. Since the pipeline overhaul in 1963, cathodic protection technology has been adopted across the board, so corrosion and perforation have not occurred in two decades. The corrosion rate dropped from 257 mils / year to 1.7 mils / year. In order to timely summary
