Pressure Stress Intensit Calculation Please provide the equation for the pressure stress intensity calculation.
In addition, please provide an example'sing the 150'F, 158 psig point from Figure 3.4.11-3 of your submittal. Provide all parameters that appear in the pressure stress intensity equation.
2.
Thermal Stress Intensit Calculation IfASME Code Figure G-2214-2 was used for the thermal stress calculation, please provide
,the detailed information needed to use the figure. Ifan equation was used instead, please provide the equation'and Young's Modulus, the coefficient of thermal expansion, and Poission's ratio. For either approach, use the 150'F, 158 psig point from Figure 3.4.11-3 of your submittal as an example, and provide values for the thermal diffusivity, heatup or cooldown rate, and wall thickness.
3.
