材质为304,温度400,压力35mpa,容积0.15L,内径58mm,如何知道厚度

用ASME Code, Section VIII, Division 1计算，不考虑腐蚀余量。12mm就够了，要求100%射线探伤！为了安全可加厚，400度用304好象不太保险！

Thickness Due to Internal Pressure [Tr]:
= (P*(D+2*CA)*K)/(2*S*E-0.2*P) Appendix 1-4(c)
= (35000.000*(58.0000+2*0.0000)*1.00)/(2*106.79*1.00-0.2*35000.000)
= 9.8271 + 0.0000 = 9.8271 mm.

Max. All. Working Pressure at Given Thickness [MAWP]:
= (2*S*E*(T-Ca))/(K*(D+2*Ca)+0.2*(T-Ca)) per Appendix 1-4 (c)
= (2*106.79*1.00*(12.0000))/(1.00
