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. For safety purpose the pressure vessel has to be designed according to ASME standards. In general the cylindrical shell is made of a uniform thickness which is determined by the maximum circumferential stress due to the internal pressure. Since the longitudinal stress is only one-half of this circumferential stress, these vessels have available abeam strength which makes the two-saddle support system ideal for a wide range of proportions. The structure is to be designed fabricated and checked as per ASME. By knowing these stresses, it is possible to determine which pressure vessel is designed for internal pressure alone, and to design structurally adequate and economical stiffening for vessel which require it. The section VIII, division 1 and division 2 are used in design. Division 1 correspond to ‘design by rule and Division 2 correspond to ‘design by Analysis’ In this paper, the horizontal pressure vessel supported on saddles is designed according to the guidelines given in Div 1 and Div 2. Efforts are made in this paper to understand the various stresses developed in pressure vessel and design the pressure vessel using ASME codes & standards to legalize the design
