摘要
介绍宝钢地区已正常输气12a,长10km,口径φ500mm的埋地煤气钢管的牺牲阳极保护系统;进行了全面的测量,并开挖检查.验证了经过12a长时间埋地输气钢管实际防腐蚀效果,为今后上海地区埋地钢管牺牲阳极保护提供了可靠的例证.
This article presents data from an overall checkup and excavating measurements of a sacrificial anodic protection system for a buried steel pipeline with a length of 10km, diameter of 500mm and a history of 12 years' normal gas-transport in Bao Steel area. 12 years' field operation showes good anti-corrosion results and provides a reliable example for the use of a sacrificial anodic protection system for a buried steel pipeline in Shanghai in the future.
