Numeric analysis of tension condition of pressure vessel for the storage of beer

Abstract

Pressure vessels during the usage are exposed under very bad working conditions which make very high tension. In this work the calculation of all the elements of vertical cylindrical pressure vessel for the storage of beer which is now in usage can influence safe work and experimenting (cylinder, torispherical heads, holes, blind flanges, cover plates and flanges). Calculation of the tension condition was done according to the standards and rules about the pressure vessels. The addition to this calculation as wall as the contribution of this work is the calculation by the usage of the Finite Element Method by usage of finite element of the thin shell type. The results we got and their analysis allow the whole approach to the mark of safety of pressure vessel in usage.

Posude pod pritiskom su u eksploataciji izložene nepovoljnim radnim uslovima koji prouzrokuju veoma visoke napone. U okviru ovog rada prikazan je proračun svih elemenata vertikalne cilindrične posude pod pritiskom za skladištenje piva koja se trenutno nalazi u eksploataciji koji mogu uticati na siguran rad i ispitivanje (omotač, danca, ojačanja otvora, prirubnice i prirubnički spojevi). Proračun naponskog stanja je urađen prema odgovarajućim standardima i pravilnicima o posudama pod pritiskom. Dodatak ovakvom proračunu kao i doprinos ovog rada predstavlja proračun primenom metode konačnih elemenata korišćenjem konačnog elementa tipa tanke ljuske. Dobijeni rezultati i njihova analiza omogućavaju sveobuhvatni pristup oceni sigurnosti posude u eksploataciji.
