[1] 中国石油大学(华东),青岛,中国

管道输送是油气能源长距离输送的重要途径。目前管道连接多采用焊接完成,焊接是一个复杂的非平衡物理化学过程,焊接接头各组成部分的成分、组织和性能都存在差异,同时还容易产生裂纹、气孔、夹杂和未熔合等焊接缺陷和较大的残余应力,使得焊接接头成为管道工程中的薄弱环节。在服役介质中,焊接接头存在宏观腐蚀电池与微观腐蚀电池耦合的多相电化学反应而引起局部腐蚀,可能导致整个构件失效,引发严重的安全事故,造成重大的经济损失甚至人身伤亡。利用 COMSOL Multiphysics® 多物理场仿真软件的腐蚀模块和二次电流分布接口对 X80 钢焊接接头在 CO2 饱和的 NACE ... Read More
