An Optimum Design of Pressure Vessel using ASME (BPVC) Sec-VIII Div-I, II and ASME (BPVC) Sec-II Part-A (original) (raw)

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.

Design and Analysis of a Typical Vertical Pressure Vessel using ASME Code and FEA Technique

As the demand for liquefied petroleum gas (LPG) continues to increase worldwide, more LPG facilities are being constructed. However, the design and manufacture of pressure vessels used to store dangerous liquids or pressurised fluids, such as LPG, has been a major cause of hazards, including explosions and leakage. In this study, we aim to address this issue by designing and analysing a vertical pressure vessel with a capacity of 10 m 3 of pressurised LPG in accordance with the American Society of Mechanical Engineers (ASME) code. Safety is the primary concern in designing pressure vessels due to the potential risks posed by accidents. Therefore, the main objective of this project is to design a pressure vessel that is safe from failure. The vessel is cylindrical with two elliptical heads, two nozzles, a manway and four leg supports, and we used Autodesk Inventor Professional 2023 for geometric modelling and Inventor Nastran for FEA analysis. To investigate the displacements, deflections and Von-Mises stresses in the pressure vessel, we used the finite element method, and Autodesk Inventor Nastran was employed for the analysis. Our results showed that changes to the structure of the pressure vessel were needed to reduce stress in the structure. Specifically, varying the LPG pressure showed an inverse relationship with the tank section shell thickness. Moreover, we observed that the factor of safety increased linearly with shell thickness. We carefully considered permissible pressures and determined the required wall thickness to ensure acceptable maximum stresses. Our results indicate that the design is safe from failure, and the highest stresses are experienced by the manway followed by the shell, while the heads, nozzles and legs support experienced the lowest stresses. We also performed a theoretical calculation for the entire model and checked the results to ensure they were within the acceptable limits. In summary, our study highlights the importance of designing pressure vessels in accordance with ASME codes to ensure safety and prevent hazards caused by improper design and manufacturing. By using the finite element method, we identified potential stress points in the pressure vessel and were able to make modifications to improve its safety.

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.

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.

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

Design and Analysis of Pressure Vessel According to Internal Design Pressure and Temperature Using FEM

Proceedings of the Second International Conference on Mechanics, Materials and Structural Engineering (ICMMSE 2017), 2017

The main objective of this study is to design and analyze the important components of pressure vessel according to the internal design pressure and temperature by using finite element method. A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from ambient pressure. They have been widely used in a variety of applications such as, in chemical industries, in thermal and nuclear power plants, in food industries, and aircraft industry. Therefore, the pressure vessels are to be designed carefully to avoid the failures which are mostly stress dependent. The requirements of stress analysis are needed to avoid the failure and the fatal accidents of pressure vessel. In this study, the important components of pressure vessel such as a blind flange, a shell flange, some eye bolts, a drain pipe, a drain pipe flange, and some junction areas of pressure vessel were specifically designed with reliable materials in accordance with ASME Code. The finite element modeling, the evaluation of equivalent stress, and the stress classification lines (SCLs) for specified points were performed using a Midas NFX program based on the finite element method (FEM). The stress analysis for the design condition involving internal pressure and thermal load has been evaluated in accordance with ASME boiler and pressure vessel code. The conclusion is that the analysis results for the normal operating condition satisfied allowable limits. Therefore, the current design of the pressure vessel has enough strength under the design load conditions.

Mechanical design of pressure vessel

The safety factor of a pressure vessel is related to both the tensile stress and yield strength for material allowance. ASME Code Section VIII has fully covered these two on the construction code for pressure vessel. This code section addressed mandatory requirement, specific prohibition, and non mandatory guidance for pressure vessel materials, design, fabrication, examination, inspection, testing, certification, and pressure relief. Mechanical design of a horizontal pressure vessel for three phase separator based on this standard had been done incorporating PV Elite software. Analyses were carried out on head, shell, nozzle, and saddle. The input parameters are type of material, pressure, temperature, and diameter and corrosion allowance. Analysis performed the calculations of internal and external pressure, weight of the element, allowable stresses, vessel longitudinal stress check, nozzle check and saddle check.
