摘　　要：ASME Ⅷ-1规范没有提及在水压工况下如何校核管板的强度。工程公司或业主在审查制造厂的计算书时会要求验证水压工况下各个受压元件的强度,尤其是管板的强度。根据换热器的不同结构型式特点,从换热器的一般打压顺序入手,提出了水压工况下验证全直径管板强度的计算公式,供设计人员参考。In accordance with ASME VIII-1,the strengths of every pressure parts are needed to validate under the condition of hydrostatic test.But in ASME VIII-1,there is no mention for how to check the strength of tubesheet in hydrostatic test.When engineering company verifies the datasheet from manufacturers,it is also required to validate the strengths of pressure parts in hydrostatic test,especially the strength of tubesheet.In this article,with different structures of heat exchangers and based on the test procedures in hydrostatic test,the equations for calculating full diameter tubesheet in hydrostatic test was presented,which may be referenced by design engineers.
