ck loadings are not a controlling design requirement (See UG-22);Р(5) 循环载荷不作为控制性的设计要求(见UG-22);РCyclical loading is not a controlling design requirement. (See UG-22)Р因此实际最低设计金属温度-29℃应免于冲击试验。.РSo actual MDMT is -29℃ shall be exempt from impact testing.Р5. 最大许用工作压力 Maximum Allowable Working Pressure ( UG-99)Р根据UG-99注释34,当计算不是用于确定最大许用工作压力时,最大许用工作压力可以假定为设计压力。因此,最大许用工作压力等于设计压力: 在60℃条件下,1.2兆帕。РAccording to UG-99 note34: the maximum allowable working pressure may be assumed to be same as the design pressure when calculations are not made to determine the maximum allowable working pressure. So the maximum allowable working pressure equals to design pressure that is 1.2MPa at 60℃.Р6. 水压试验压力 Hydrostatic Testing Pressure ( UG-99)Р根据UG-99( b)和第二卷D 分册表1A, 试验温度的应力值St 是138兆帕( SA516M Gr.485) ,壳体和封头的设计温度应力值
