摘　　要：涂层防腐通常分为外防腐和内防腐两类。管道内防腐现场补口质量决定着整条管道的"命运",这项工作存在难度大、工艺复杂、技术要求高等困难。为了能够提升沙漠地区特殊环境下管道内防腐现场补口的质量,通过沙漠地区管道内防腐现场补口作业的实践与探索,从流动风沙、起伏沙丘和温差等三方面对影响补口质量的因素进行了分析,并对这些影响因素采取了必要的措施加以消除。经过现场实际应用,诸项措施均取得了良好效果,值得在沙漠地区管道内防腐现场补口施工中推广借鉴。Application of corrosion preventive coatings in pipeline walls is one of pipeline corrosion control methods.Pipeline corrosion control by using corrosion preventive coatings includes internal and external corrosion control.Up to now,external corrosion control technologyis relativelymature due toits simple construction and less effect factors,while internal corrosion control is restricted by construction site conditions,construction equipment,testing equipment and pipeline diameters and other factors,especially,internal corrosion field joint coating will determine the quality of whole pipeline.Through practice and exploration of desert area pipeline coating defect repair operation,found out are some factors affecting the quality of coating defect repair,taken are some necessary measures to eliminate such factors and achieved are good results.
