L360QS/NO8825复合管母材及焊缝腐蚀性能研究

摘要

基于油气储运工程中油气管道的腐蚀问题，本文对L360QS/NO8825复合管母材及焊缝在不同温度下的耐蚀性能进行了研究，结果表明L360QS/NO8825复合管母材及焊缝在四种不同温度下均具有较好的耐蚀性能，满足油气储运工程中性能要求。%Based on the corrosion problems in Oil-gas storage and transportation engineering, the corrosion resistance of base metals and welding metals of L360QS/NO8825 composite pipes under different temperatures has been researched. It is concluded that the base metals and welding metals of L360QS/NO8825 composite pipes present excellent corrosion resisting properties in all the experienced temperatures which meet the requirements in Oil-gas storage and transportation engineering.
