摘要
随着川东北高酸性气田的开发,集输系统普遍采用湿气加热保温混输工艺,要求采取更为完善的腐蚀控制技术,高酸性气田开发集输系统集输管线技术,管线外防腐采用"防腐保温层+阴极保护"技术,内防腐采用缓蚀剂涂膜与连续加注技术,最大程度上减缓恶劣工况下介质对设备和管道的腐蚀。
With the high acidity gas field development in the northeastern Sichuan, gathering and transportation system commonly used heat insulation moisture mixed transportation process, and calls for a more comprehensive corrosion control technology, the development of high acid gas gathering system pipeline gathering and transportation pipelines outside the anti-corrosion technology ＂anti-corrosion cathodic protection insulating layer technology, the use of anti-corrosion inhibitor coating and continuous filling technology to maximize the harsh conditions slow media equipment and piping corrosion.
