Design Investigation into the Stress at the Base of a Nozzle of a Pressure Vessel

INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY, 2014

A pressure vessel typically consists of large cylindrical and / or spherical containers with nozzles through which the reactants flow in and out. . While plain cylindrical or spherical containers can be analyzed for internal pressure using thin/ thick cylinder formulae, the ones with nozzles are difficult to analyze. This is in view of complicated stress concentrations that arise at the interface of the nozzle and pressure vessel junction. The calculations have become complicated because of forces that arise at the free end of the nozzle. The forces include those of piping, wind forces, earth quake forces in addition to the internal pressure. In spite of these, strict adherence to safety codes is to be followed. ASME, Section VIII specifies the stress limits to be adhered to. One of the criterions is the stress intensity, which is not possible to compute by simple analytical procedures. FEM can be used for computing the deformation and stress at the nozzle-vessel junction in the structure and also at all other points on the pressure vessel. Quite often the geometric models are imported from CAD files for mesh generation with tetrahedral elements. Engineers generally use shell elements or tetrahedral elements while modeling the reactor vessels. But, precise estimation of stress intensity is not possible with these elements for a structure with nozzles. A method is developed for a precise structured modeling and for estimating the stress intensities at the junction of nozzles and pressure vessels. The structure of a reactor vessel of diameter 1900mm and length of 3600mm with a nozzle will be modeled and analyzed. The pressure load is 7 MPa. Stresses have been estimated. The induced stresses are compared with allowable stress. Based on the induced stress in the Pressure vessel three additional design variants have been studied to bring the stresses within allowable limits

Stress Analysis of Pressure Vessel

International Journal of Innovative Science and Research Technology, 2021

Tanks, vessel and pipelines that carry, store or receive fluids are called Pressure vessel. A pressure vessel is defined as a container with a pressure differential between inside and outside. The inside pressure is usually higher than outside. The fluid inside the vessel may undergo a change in state as in case of a steam boiler or may combine with other reagent as in the case of chemical reactor. Pressure vessel often has a combination of high pressure together with high temperature and in some case flammable fluids or highly radioactive material. Because of such hazards it is imperative that the design be such that no leakage can occur. In addition, vessel hat to be design carefully to cope with the operating temperature and pressure. In this paper, the analysis on pressure vessel with variation of hole and outside temperature variation is carried out to find the stresses in pressure vessel. First, the finite element approach is used to evaluate the stresses in the closed pressure vessel and with varying material and outside temperature. Further the finite element approach is used to evaluate the stresses in the pressure vessel with holes on circumference and with varying material and outside temperature.

A Review Paper on Study of Pressure Vessel, Design and Analysis

Pressure vessels are containers used to handle fluids which are highly toxic, compressible and which work at high pressures. Pressure vessels have applications in variety of industries such as Oil and Gas, Petroleum, Beverage industries, chemical industries, power generation industries, food industry, etc. Failure of pressure vessels has adverse effects on the surrounding and the industry which can cause loss of life, property and damages. The design of pressure vessel depends on factors such as pressure, temperature, material selected, corrosion, loadings, and many other parameters depending on the applications. This paper elaborates the work done in design of pressure vessels to reduce failures in the pressure vessels and study of the parameters such as material selection, operating pressure and temperature, design, analysis, etc. which cause fatigue failure or stress concentration in the vessels. The use of Finite Element Methods and Analysis techniques that provide results on failure in pressure vessels are to be studied. The future scope and advancements in pressure vessel design with software's is to be studied.

DESIGN AND ANALYSIS OF PRESSURE VESSEL

The main purpose of the project is to design a pressure vessel according to ASME standards and do thermal analysis on the pressure vessel made up of different types of materials by varying the shell thickness of the vessel for various ambient temperature. Thus, comparing the results to find the optimum thickness for which the pressure vessel is safe to use in industry. A worst case scenario is also considered for which a crack is present on the external surface of the pressure vessel. Fracture mechanics is used to analyze the different geometry of crack for different kinds of material. Thus, predicting the extent to which the pressure vessel is safe for use.

ANALYSIS OF STRESS CONCENTRATION AT OPENING IN PRESSURE VESSEL USING ANOVA

Pressure vessels are used for storage, transportation and application of energy and fluids and also for carrying out reaction s and many other purposes. Openings in tanks and pressure vessels are necessary to carry on normal operations. Openings are generally made in both vessel shells as well as heads. Unfortunately, these openings also result in penetrations of the pressure restraining boundaries and are seen as discontinuities. Nozzles represent one of the most common causes for stress concentration in pressure vessels and stress concentration factors can be very useful in pressure vessel design. Finite Element Analysis is very efficient method for determination of stress concentration factors; however reliability of Finite Element Analysis should always be assessed.

Review on Stresses in Cylindrical Pressure Vessel and its Design as per ASME Code

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

The ASME Boiler and Pressure Vessel Code (BPVC) standards are used for the design and fabrication of boilers and pressure vessels. ASME section viii division 1 follows design-by-formula approach while division 2 contains a set of alternative rules based on design-by-analysis approach. Div.2 has procedure for the use of Finite Element Analysis (FEA) to determine the expected stresses that may develop during operation. A solid model, pressure vessel having nozzle is created by using Design Modeler of ANSYS program. For given boundary and loading conditions, the stress developed is analyzed using mechanical workbench of ANSYS software. After analysis, it is found that maximum localized stress arises at the nozzle to shell interface near the junction area. The results obtained shows that the nozzle design is safe for the design loading conditions.

Design and Evaluation of Pressure Vessel as per ASME Section VIII Division 2

This paper deals with the Finite element design and evaluation of pressure vessel. Pressure vessels are used to contain a multitude of things, including air, water, chemicals, nitrogen, and fuel. They are used in petroleum refining, food and beverage automotive and transportation, oil and gas and in chemical industries. High pressure is developed in pressure vessel and has to withstand several forces developed due to internal pressure hence pressure vessel design is quit complex as it satisfy the ASME standards and its functional aspects, safety and life requirements. ASME section VIII, Division 1 and Division 2 are normally used in design. The Division 1 corresponds to Design by rule whereas the Division 2 corresponds to Design by analysis. The aim of this project is to design a pressure vessel whose sole purpose is to withstand the pressure of the substance stored in it and is analysed by FEM to validate its design for their operational stress levels and safety. The Allowable stress limits for Stress Categories to find the Stress Intensity Limits are considered as per Part 5 of ASME Section VIII Division 2 and The Fatigue Analysis to be carried out in accordance with ASME Section VIII Division 2.
