摘要
为从安全性和经济性两方面对在役压力管道缺陷的形态作出可靠的评价 ,在分析SAPV、R6、PD6 493、B31.G、API5 79等国内外先进评价规范特点的基础上 ,结合我国在役压力管道的现状 ,研制开发了适用于含平面缺陷和 /或体积缺陷在役压力管道剩余强度评价系统及软件。通过事故实例分析、在役含缺陷天然气压力管道剩余强度评价的应用以及含缺陷压力管道全尺寸试验结果对比 ,表明本系统的评价结论是可靠的 ,同类缺陷各评价等级之间的衔接是合理的。
An assessment system remaining strength of OPPCD was developed based on the advanced assessment standards,including SAPV,R6,PD6493,B31.G,API579.The system applies to the piping containing plane defects and/or volume defects,it can give such parameters as possible failure mode,limit load,limit defect dimension,etc. and present the dynamic analysis of sensitivity.For volume defects,it can present safety level,required minimum wall thickness,limit defect dimension,and maximum allowable load.The example analyses of several accidents and the whole dimension test for piping containing defects are compared with the assessment results.It proves that the system is reliable and the link for various grades of assessment is reasonable.
