摘要
比较RSE-M规范和ASME规范Ⅺ卷对在役检查检测方法的规定,分析两个规范中相关规定的相同点和不同点。分析认为:RSE-M规范和ASME规范Ⅺ卷均采用了七大常规无损检测方法;RSE-M规范对于特定的检验对象规定了具体检验方法,ASME规范对于检验方法的规定一般按类;RSE-M规范中声发射方法用于缺陷扩展和水压试验时的泄漏检测,ASME规范中声发射主要用于缺陷扩展的监测;RSE-M规范中涡流检测方法作为体积检验方法,ASME中涡流检测根据具体检验情形视为表面检查或体积检测;ASME规范对于检验方法的替代规定较为宽松。
With a comparison between the regulations for nondestructive test methods for in-service inspection under RSE-M and those under ASME BPV-Ⅺ,the similarities and differences between the two are analyzed in detail.It is iden-tified via the analysis that the said two specifications both adopt the seven common-used major nondestructive test methods.RSE-M specifies detailed inspection methods as for specific inspection objects,while ASME specifies the inspection methods as per inspection categories.And the acoustic emission method under RSE-M is used for leakage monitoring during defect extension and hydrostatic testing,while the same method under ASME is mainly used for monitoring defect extension.Under RSE-M,the eddy monitoring method is used as a volume inspection method,while under ASME,the same inspection method is used for the purpose of surface inspection or volume monitoring just as per the specific inspec-tion status.Furthermore ASME describes rather generous regulations for substitution of the inspection method.
