        ASMEⅧ-2,即BPVC Section VIII-Rules for Construction of Pressure Vessels Division 2-Alternative Rules,6月30日起已经开始接受全球预定了,价格$570.00。目前已有电子版,需要的可发邮件来。

        2013版中所有的变化都将直接修改到对应的位置,并作出标识。关于变化内容摘要的列表中,除了列出变化的内容还附加变化的性质。2013版及以后的版本不会再有增补了。

        2013版分析设计篇的主要变化如下:

         1.允许使用其它公认的载荷标准来确定风载荷和地震载荷。修改了风载荷的载荷组合系数。

         2.修改了一次局部薄膜和一次局部薄膜加弯曲的应力极限。对应地,修改了图5.1。

         3.要求疲劳分析时考虑接头对准和焊缝棱角。

         4.修改了基于等效总应变范围的疲劳罚系数计算公式。

         5.在简化的弹塑性分析的P+Q校核中排除了所有的热应力,并增加了薄膜热应力棘轮校核准则。    

       ASMEⅧ应用范围的简介如下:

        This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig.  Such vessels may be fired or unfired.  This pressure may be obtained from an external source or by the application of heat from a direct or indirect source, or any combination thereof.  These rules provide an alternative to the minimum requirements for pressure vessels under Division 1 rules.  In comparison the Division 1, Division 2 requirements on materials, design, and nondestructive examination are more rigorous; however, higher design stress intensify values are permitted.  Division 2 rules cover only vessels to be installed in a fixed location for a specific service where operation and maintenance control is retained during the useful life of the vessel by the user who prepares or causes to be prepared the design specifications.  These rules may also apply to human occupancy pressure vessels typically in the diving industry.  Rules pertaining to the use of the U2 and UV ASME Product Certification Marks are also included.

        BPVC的简介如下:

        Since its first issuance in 1914, ASME’s Boiler and Pressure Vessel Code (BPVC) has pioneered modern standards-development, maintaining a commitment to enhance public safety and technological advancement to meet the needs of a changing world.  More than 100,000 copies of the BPVC are in use in 100 countries around the world.
