ASME Section VIII, Div.1 Appendix 1-4
(OP)
Hi all,
for an ellipsoidal head designed to UG-32(d), Appendix 1-4 (f) must be considered when t/L<0.002. 1-4(f)(1)(h)(2) sets limits of 0.0005<=t/L<=0.002. What does one do in the case where one has a large diameter, low pressure dished end, where t/L<=0.0005? Is ASME VIII, Div.1 implying that if t is so calculated that t/L<=0.0005, then some other design code should be used?
Your comments, please.
Thanks in advance.
John

If it's a new vessel then you just need to calculate the thickness needed and specify it in the purchase documents.
