通过对格尔木—拉萨的成品油管道进行全面腐蚀情况检测和防腐补漏工作,发现该管道腐蚀问题比较严重,一方面,防腐层老化、剥离并遭到破坏;另一方面,穿跨河流、冰丘、冰锥、盐碱滩、沼泽地段的管道出现腐蚀穿孔。出现严重腐蚀的原因是设计、施工的缺陷、复杂的地理地质条件和管理使用方面的问题。介绍了采取的相应措施,即加强阴极保护系统的管理、管道防腐检漏、补漏以及管道水工保护工作。同时还就格拉管道防腐问题提出了看法和建议。
Through the comprehensive corrosion detection and corrosion protection of the refined oil pipeline in Golmud-Lhasa, it was found that the corrosion of the pipeline was serious. On the one hand, the anti-corrosion coating was aged, stripped and destroyed; on the other hand, , Ice cone, saline beach, swamp sections of the pipeline corrosion perforation. The causes of serious corrosion are the design and construction defects, complex geo-geological conditions and management problems. Introduced the corresponding measures taken to strengthen the cathodic protection system management, pipeline corrosion detection, trapping and pipeline protection work. At the same time also put forward the views and suggestions on the anti-corrosion of Gera pipeline.
