Dear all,

There in CAESAR2 only TGE/TD/12 code allow inputing +mill tolerance,for other codes,how to deal with it?There I met a power pipe,which inside diameter is 635mm,thickness is 31mm,temp. 545 degree and pressure 4.2MPa.The vendor can only guarantee the minimum inside diameter,for the wall thickness,the +mill tolerance is nearly up to 25%.The pipe have to be analyzed based on B31.1 code according the specification.I do not know how to model the pipe with this program.If I adopt the thickness of 31mm,what my concern is the 25% +mill tolerance maybe lead to some points overstress and some supports and equipment nozzle overload.If I do not adopt this thickness,what shall I do???
Any useful suggestion and guidance will be highly
appreciated!
