埋地钢质管道外防腐层的选择及运用

Selection and Application of External Anti-corrosion Coating for Buried Steel Pipeline

对气田长输管线而言,管道外防腐层是一个重点。从埋地钢质管道外防腐层的性能要求出发,介绍了外防腐层常见方案和运用原则,并结合四川气田进行分析,为进一步提高管道防腐性能提供新的思路。

For long-distance gas field pipeline,the external anticorrosive coating is a key point.Based on the performance requirements of the external anti-corrosion coating of buried steel pipeline,this paper introduces the common schemes and application principles of the external anti-corrosion coating,and analyzes it in combination with Sichuan gas field,hoping to provide new ideas for further improving the anti-corrosion performance of the pipeline.
