Nozzle hub-thickness
Nozzle hub-thickness
(OP)
hello evreyone ;)
i'm a new designer engineer, plz help me
1. how can i choose between diffrent sketch in fig UG-40 (asme viii div 1) to design a nozzle and how i choose if the nozzel set-in ou set-on and self rienforncing or not?
2. how can i calculate (tx) and (te) in sketch (e) Fig UG-40?
Note 1 : i'm using hand calculation , i haven't a softwar.
Note 1 : i'm a fresh designer engineer, so maybe these questions are basic questions so if someone can help me to design
a pressure vessel from biginig until stress analysis i will be thankful, i did thickness calculation for heads and shell and i have some difficulties for nozzle neck and rienforcement and wind, seismic stress calculations.
thank you,
Houari Yahia

You can always learn a certain amount on you own, and it is good practice, but if you hope to achieve some level of competence any time soon, than pay attention to XL83NL's reply. Get some mentoring, get some training, get some software. If nothing else, start building you own spreadsheets or programs. Doing calculations by hand is illustrative and a worthwhile experience, but no working designer has the time for it.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

You can do ASME code by hand, but it is very time consuming. Major items (shell, head thickness) are quick and easy. Minor items (strength of reinforcing, etc.) are simple in theory but get complicated by having a mass of details.
There are vessel design short courses that will help quite a bit, still not a substitute for working with somebody else.

XL83NL thank you for your reply, and i look for a basic pressure vessel design if possible to understand asme code... and i will search for training in the futur.
SnTMan (Mechanical) thank you for your reply but i didn't find note 3 in fig UG40? plz tell me the number of page?!
JStephen : thank you very much, i do calculation to prepar an excel spreadtsheet to more calculation pressure vessel.
