    Abstract： In many oil fields of China，high salinity of groundwater has corrosive effect on metal pipelines （steel pipelines）. In Tarim basin，the surface of the soil with high salinization and groundwater with high salinity，rich in chlorine ion，hydrogen sulfide and carbon dioxide，are the main corrosion source of the metal pipelines. With continuous exploitation of Tazhong Oilfield，its moisture content rises year by year，the pipeline corrosion is more and more serious，leaking phenomenon happens ceaselessly and cracking appears even，which tremendously affects safety of the oilfield. After experiment and exploration for several years，Tarim Oilfield has found a new alternative pipeline material，that is，flexible clad pipe，which can replace metal pipe. Field application of such flexible clad pipe in recent several years has achieved good results，so it is worthy of popularization.
