摘要
埋地钢质管道的外防腐层是管道防止腐蚀破坏的屏障。目前国内许多埋地管道普遍存在严重腐蚀问题,这是由于管道防腐整体性能下降所导致的,文中通过检测实例探讨了埋地管道防腐整体性能的检测方法,并对管道的运行维护给出了合理建议。
The external corrosion protection layer of buried steel pipeline is the shelter for preventing pipeline from corrosive damage. Many buried steel pipelines at home have severe corrosion problem,which is caused by the total decrease of pipeline corrosion protection performance. With detection examples,this paper discussed the detection methods for holistic performance of buried pipelines in corrosion protection,and provided reasonable suggestions for pipeline operation and maintenance.
