摘　　要：输油站热媒—水换热器经多年运行后,由于循环水中含有铁、钙、镁离子和氯离子以及溶解氧含量高,致使热交换设备和管网的腐蚀、结垢严重,导致局部腐蚀穿孔。采用IMC-50-S缓蚀剂,在腐蚀严重的沈阳和熊岳输油站进行了现场试验,试验结果表明,加剂后可使其腐蚀速度控制在0.1mm/a以下,延长了换热器和循环管网的使用寿命,保证了输油安全生产。Due to the ferric ion,calcium-magnesium ion and chlorion as well as high content DO contained in the recirculated water,scale deposit,corrosion and corrosion hole occurred in heating medium-water heat exchangers and pipe networks after they were put into years operation in pump stations. Field tests for IMC-50-S inhibitor have been made in Shenyang and Xiongyao pump stations. The inhibitor tests results show that the corrosion rate has been reduced below 0. 1 mm/a,which prolongs the service life of heat exchanger and pipe networks.
