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.
