摘　　要：为考察00Cr22Ni5Mo3N双相不锈钢在中国西部某气田雅丹地貌环境的腐蚀行为及对其施加阴极保护的必要性,采用现场埋设试片的方法,通过对试片的腐蚀速率、腐蚀形貌分析,研究了其腐蚀行为特征。结果表明:00Cr22Ni5Mo3N试片在该土壤中的平均腐蚀速度低,适用于该气田集气管线,并无施加阴极保护的必要性。In order to evaluate the corrosion behavior of 00Cr22Ni5Mo3 N duplex stainless steel in Yardang soil of gas field located in West China and the necessity of cathodic protection,the characteristics of corrosion behavior were studied by analyzing the corrosion rate and corrosion morphology of sample using coupon tests.Results showed that the average corrosion rate of 00Cr22Ni5Mo3 N sample in the soil was low,which indicated that the sample was suitable for gas-gathering line in gas filed and there was no need to take cathodic protection.
