The main objective of this work is to designnozzle for pressure vessel according to ASME code. Thedesign methodology of components of the nozzle like neck,reinforcement, and flange has been explained through thiswork. Design of 32”nozzle has been carried out according torequired flow rate of hydrocarbon fluid based on internalpressure and temperature and external loading. This workgives the analytical result for all the component of pressurevessel. It also shows effect of thickness of Gasket and effectof no of bolt of weld neck flange on seating pressure.Key words: Nozzle, Flange, Pressure Vessel, ASME BPVCCode, Nozzle Reinforcement1.42, where R is radius of head and h is depth of head [1]. Thebest solution for locating the nozzle in vessel head is to placeit in the axis of symmetry of the vessel axis. When the nozzleis placed at various distance from the axis of symmetry of thevessel the high stress occurred in nozzle junction. So thelimiting distance from axis of symmetry is 0 to 0.8R where Ris radius of the vessel [2]. In pressure vessel heads theflexibility of nozzle has to be investigated. The flexibility ofnozzles play an important role in both piping flexibilityanalysis and vibration analysis .flexibility of nozzles inellipsoidal heads can be appreciably higher than those inhemispherical heads for same vessel diameters [9].I. INTRODUCTIONNozzle is one type of opening in pressure vessel. A pressurevessel cannot be imagined without a nozzle. It is a devicedesigned to control the direction or characteristics of a fluidflow, different types of nozzles used are inlet, outlet,manways, sump, indicators, and safety valves. In the nozzlethere are components like neck, reinforcement pad, flangesand their methodology is explain in this paper. All this designmethodology are done based on ASME boiler and pressurevessel code, pressure vessel design manual Dennis moss andsome research papers. For pressure vessel there are variousconstruction available for nozzle according to code are 1.Nozzle with pipe & Flange, 2. Nozzle with pipe &reinforcement 3.long weld neck type nozzle, 4. Selfreinforcement nozzle. A neck is small pipe used indetermining diameter of nozzle. The annular circular plate isprovided around the opening in the form of pad known asreinforcement pad. A piping flange is device used to connectpiping and components in piping system by use of boltedconnections and gasket. Result contain complete calculationof 32” nozzle for Knock out Drum and Some Graphsregarding to flange and stress.II. BASIC CONSIDERATION IS CONCERN BEFORE DESIGNINGOF PRESSURE VESSEL NOZZLEBefore the start the design of the nozzle keep followingconsideration first,1) Location2) Material Selection3) Maximum allowable nozzle loadA. LocationNozzle can be attach to different components of pressurevessel i.e. shell, head and sump at various positions. Basicgeneral categories of head are hemispherical, tori sphericaland ellipsoidal. For all the load categories, high stressesoccurred at the vessel-nozzle junction as there is a severegeometric discontinuity. At the knuckle region of head highcompressive stress occurred so design of nozzle in radialdirection must be careful at knuckle region. Hoop stress in theknuckle become compressive when the ratio of R/h exceedsFig. 1: Nozzle Locations, [1]As the nozzle and shell were of cylindrical shape;the axis of the nozzle lies in the plane perpendicular to theaxis of the cylindrical shell. The angle (θ) which the nozzleaxis forms with the tangent to the shell that passes throughthe penetration point of the nozzle a
of material for nozzle is selected from ASME BPVC Section II Part D. C. Maximum Allowable Nozzle Load It establishes the minimum criteria for design by providing the maximum allowable nozzle load by size and class of flange rating. This is an alternative work process to determining each individual nozzle load after the piping .

Regarding with the appropriate structural design of the pressure vessel, the optimization approach has paid much attention by many researchers both in practice and research.
