一、引言自1946年墨西哥湾铺下第一条海底管道,迄今世界各地已铺设海底管道4万余公里。墨西哥湾的海底环境,北海的汹涌浪涛。不但孕育了海底管道工程,同时也促进了相关技术的发展和提高。其中,用于海底管道的防腐蚀涂层就是一个重要的技术领域。据资料统计,在墨西哥湾1967～1979年间,所发生的240起管道泄漏事故中,就有43%是由腐蚀引起的。在防腐蚀措施中, I. INTRODUCTION Since the first submarine pipeline was laid in the Gulf of Mexico in 1946, up to now, more than 40,000 kilometers of submarine pipelines have been laid all over the world. The seabed environment in the Gulf of Mexico, the surging waves of the North Sea. Not only gave birth to the submarine pipeline project, but also to promote the development and improvement of related technologies. Among them, the anti-corrosion coating for submarine pipelines is an important technical area. According to statistics, in the Gulf of Mexico from 1967 to 1979, there were 240 pipeline leaks, of which 43% were caused by corrosion. In anti-corrosion measures,
