摘　　要：外腐蚀直接评价(ECDA)是油气管道完整性管理的重要手段,其通过各类检测技术对管道防腐系统及外部腐蚀进行科学检测与评价,确定经济合理的维修方案和预防措施。如何将ECDA技术合理高效地应用于国内长输管道是当前管道保护的重要任务。开展了长输成品油管道ECDA实践研究,结果表明:ECDA应用于长输成品油管道外腐蚀检测评价效果良好,检测管道外腐蚀危害轻;提出管道外腐蚀防护维修维护方案,为管道的维修维护与监控提供数据支持。提出应加强管道完整性管理中的数据完整性管理,综合运用外检测技术与其他检测技术,重点解决外检测技术应用中出现的特殊问题,积极探索检测评价的信息化技术,有效提高ECDA工作的效率和信息化水平。External corrosion direct assessment （ECDA） was an important means of oil and gas pipeline integrity management, it made the economic and reasonable maintenance plan and preventive measures through scientific testing and evaluation by all kinds of testing technology for pipeline corrosion protection system and external corrosion, so how to apply ECDA technology reasonably and efficiently to the domestic products oil pipeline was an important task of pipeline protection. ECDA application research on products oil pipeline was carried out. The results show that application effect of ECDA to products oil pipeline corrosion testing evaluation was good, and the pipeline external corrosion was light. The research provided the data support for pipeline mitigations and monitoring. Repair and maintenance of pipeline external corrosion protection scheme was further put forward. Data integrity management and the integrated using of all kinds of detection technology should be strengthened. Most attention should be focused on the special problems in detection and information technology to effectively improve the efficiency of ECDA.
