摘　　要：对输送天然气管线外腐蚀情况进行了调查和腐蚀因素的分析,管线外壁防腐蚀层有一半以上老化破损,且土壤含盐量高,电阻率低,pH值低,对钢铁有强的腐蚀性,造成外腐蚀严重。为有效延长管道的使用寿命,采用管外补加阴极保护补救的防护措施。An investigation of the corrosion and the corrosion reasons of the gas pipeline from liutun to wenliu was conducted. The outside wall of the pipeline was corroded because of the strong corrosion factor of the soil such as high salinity and low electric resistivity etc and aging of outside protective layers. Some suggestions such as adding cathodic protection etc have been adoptted to prolong the using time of the pipeline.
