全面腐蚀控制第37卷第10期2023年10月1专论Monograph技术舰船腐蚀海水管路剩余强度评价方法研究综述张鲁君1吴晓阳1潘兴隆2(1.武警海警学院机电管理系,浙江宁波315800;2.海军工程大学动力工程学院,湖北武汉430033)摘要:为建立舰船腐蚀海水管道剩余强度评价方法,综述了现行评价腐蚀管道剩余强度的相关标准和方法的理论基础,对比分析了不同评价方法的适用性和先进性。腐蚀管道剩余强度评价公式都是基于断裂力学的半理论半经验公式,主要区别在于流变应力、系数鼓胀系数和腐蚀面积计算方法等不同。DNVRP-F101标准适用于含复杂腐蚀缺陷,且同时承受内压和轴向载荷的中高强度管道,先进性较高,可基于DNVRP-F101标准建立舰船腐蚀海水管路剩余强度评价方法。关键词:舰船腐蚀管道承压能力评价方法对比分析中图分类号:U674.7+07文献标识码:ADOI:10.13726/j.cnki.11-2706/tq.2023.10.001.08AreviewonEvaluationMethodsforResidualStrengthofWarshipCorrosiveSeawaterPipelinesZHANGLu-jun1,WUXiao-yang1,PANXing-long2(1.ApartmentofMechatronicsManagement,ChinaCoastGuardAcademy,Ningbo315800,China;2.CollegeofPowerEngineering,NavalUniversityofEngineering,Wuhan430033,China)Abstract:Inordertoestablishamethodforevaluatingtheresidualstrengthofshipcorrosiveseawaterpipelines,thetheoreticalbasisofthecurrentstandardsandmethodsforevaluatingtheresidualstrengthofcorrodedpipelinesisreviewed,theapplicabilityandadvancednatureofdifferentevaluationmethodsarecomparedandanalyzed.Theresidualstrengthevaluationformulasofcorrosionpipelinesareallsemi-theoreticalandsemi-empiricalformulasbasedonfracturemechanics,andthemaindifferencesarerheologicalstress,Foliasexpansionfactorandcorrosionareacalculationmethod.Amongthem,DNVRP-F101standardissuitableforevaluatingmediumandhighstrengthpipelinescontainingcomplexcorrosiondefectsandbearingbothinternalpressureandaxialload,whichhashighadvance,theresidualstrengthevaluationmethodofshipcorrosionseawaterpipelinescanbeestablishedbasedonDNVRP-F101standard.Keywords:warship;corrosionpipeline;pressure-bearingcapacity;evaluationmethod;comparativeanalysis作者简介:张鲁君(1993-),男,山东巨野人,助教,硕士,主要从事舰船机械设备故障检测方面...
