    ASME SA/SB XYZ和ASTM A/B XYZ同數(shù)字編號不銹鋼鋼管標(biāo)準(zhǔn)的差異分析及啟示

    Analysis of and Enlightenment from Differentiation between Specifications for Identical Digital-coded Stainless Steel Pipes under ASME SA/SB XYZ and ASTM A/B XYZ

    • 摘要: ASME SA/SB XYZ不銹鋼鋼管標(biāo)準(zhǔn)是以ASTM A/B XYZ同數(shù)字編碼不銹鋼鋼管標(biāo)準(zhǔn)為基礎(chǔ)審定后列編在ASME B&PVC材料篇中的材料選材標(biāo)準(zhǔn)。除了奧氏體不銹鋼鋼管ASME SA/SB XYZ對ASTM A/B XYZ有個別條款修改外，兩者是基本或完全等同的。而ASME SA/SB對ASTM A/B同數(shù)字編碼奧氏體不銹鋼鋼管標(biāo)準(zhǔn)的修改主要是針對H級不銹鋼鋼管的熱處理要求及操作細(xì)節(jié)。列舉了兩種標(biāo)準(zhǔn)的差異條款的細(xì)節(jié)及要點(diǎn)，討論了其緣由或背景，提出了啟示和疑惑。

       

      Abstract: The specification for stainless steel pipe of ASME SA/SB XYZ is made on the basis of the specification for the stainless steel pipe with the same digital codes under ASTM A/B XYZ，and listed in ASME B&PVC Section 11 Part A&B and used for material selecting. In fact，contents of different sections of the said two specifications are almost the same，or identical except certain articles concerning austenitic stainless steel pipe under Specification ASME SA/SB XYZ which result from amendments of correspondent articles under Specification ASTM A/B XYZ. And the amendments are made mainly addressing to the heat treatment requirements and operation procedures for the Grade H stainless pipe. Cited in the essay are the details and critical points concerning the different articles under the two specifications， and also elaborated are relavant reasons， background， and enlightenment and questions.
