Abstract

A pressure vessel is defined as a container with pressure differential between inside and outside, except for some isolated situations. High pressure is developed in pressure vessel so pressure vessel has to withstand several forces developed due to internal pressure so selection of pressure vessel is most critical. The fluid inside pressure vessel may undergo state of change like in case of boilers. Pressure vessel has combination of high pressure together with high temperature and may with flammable radioactive material because of hazards it is important to design pressure vessel such that no leakage can take place as well as pressure vessel is to be designed carefully to cope with high pressure and temperature plant safety and integrity are of fundamental concern in pressure vessel design and these depends on adequacy of design codes. For safety purpose pressure vessel has to be designed according to ASME standards. The equations found in ASME code books rarely provide real stresses that can be used to compute permissible cycle life. Equation for items such as Heads, Flanges, Nozzle and others are design rules which safety make their use acceptable. To get stress values for cycle life calculations, it is usually required to run a Finite Element Analysis (FEA) cannot predict real stresses in any particular location of a vessel. Large factors of make their use acceptable. To get stress values for cycle life calculations, it is usually required to run a Finite Element Analysis (FEA).
