Hello everybody.
After recalculated vessel primarily designed by ASME using AD-2000 . I obtained for heds and achell
similar results as regards strenth but big difference in fatigue assesment .
Allowable no. of cycles fol cylindricall part N = 200 000 after AD-2000 , and N = 10 600 000 after ASME. I can use ASME Section VIII Division 1 only so i can´t check the original ASME calculation.
Who can tell me what is the N after ASME for cylinder ID=1000mm, Length= 1000mm,
Shell thick=30mm, Corr.all=7mm
Join eff.=0,85 , Material- UNS S31803 (A-240) , Temp=218 deg .C , Fluctuation 0/24 bar
Cylinder made without inperfections with 1 L,seam.
