Abstract
This study addresses the prediction of the burst pressures and burst failure locations of the vehicle toroidal liquefied petroleum gas (LPG) fuel tanks using both experimental and finite element analysis (FEA) approaches. The experimental burst test investigations were carried out hydrostatically in which the cylinders were internally pressurized with water.
Abstract
High-pressure facilities such as pressure vessels and storage equipment are widely used in all areas of manufacturing. Although many safety regulations have been enacted, mechanical defects and system operator errors sometimes cause industrial disasters. Since industrial disasters at high-pressure facilities cause greater loss of life and property, the installation of pressure-relief devices is mandatory.
Abstract
Rupture disc has been one of the most effective equipment to prevent overpressure from explosion for the pressure equipment. The performance of bursting at the predetermined pressure is critical to rupture disc, which was decided directly with the dimensional accuracy of the rupture disc such as thickness, radius value and arch height.
Abstract
Conceptual design of pressure relief systems is an important stage in the design of a safe process plant. The conceptual design stage consists of the following steps: deciding on the location of pressure relief devices, selecting the general type of pressure relief device for each identified location, i.e. safety valve and/or bursting disc (rupture disc), or other relief device, and selecting the special features for the chosen device type.
Abstract
In this paper the results of a multi-year analysis of the pressure relief devices located in several plants in major chemical sites are summarized. The analysis consisted of a systematic evaluation of existing safety valves and rupture discs including the identification of the service conditions and design cases as well as the sizing calculations of the individual device and associated piping.
Abstract
This paper provides a comparison between finite element analysis results and test data from the Pressure Vessel Research Council (PVRC) burst disk program. Testing sponsored by the PVRC over 20 yr ago was done by pressurizing circular flat disks made from three different materials until failure by bursting.
Abstract
Jones and Holliday recently reported simulations of clamped circular disks employing a continuum finite element method and elastic/plastic material models. An interesting conclusion of that work is that using a small strain small deflection elastic perfectly plastic model ~SSSD EPP in the notation of is a conservative way to estimate burst pressures. Limit analysis based closed-form expressions for collapse loads of clamped uniformly loaded circular plates exist in the literature.
Abstract
This paper presents a numerical methodology which aims to improve 3D thin sheet hydroforming processes. This methodology is based on elastoplastic constitutive equations accounting for non-linear anisotropic hardening. The experimental study is dedicated to the identification of material parameters from the global measure of sheet displacement, thickness evolution and internal pressure expansion.
Abstract
Pressure control valves are used in fluid power systems to control the operation of the hydraulic
system. The time response of a hydraulic system is the integrated result of the response times of all of the components used in the system. The ability to understand and manage the valve performance characteristics like transient response, pressure-flow are important in automation and heavy industrial processes.
Abstract
With the advent of computers many of the critical components of Engineering are being designed successfully using Finite Element Analysis. The rupture disc used for safety in Chemical & PetroChemical Industries is one of the critical components where the design has to be done for failure of the material than the usual design problem of Engineering Design which is designing for strength.
Abstract
There are tens of thousands of industrial manufacturing facilities operating throughout the world. Each chemical plant, petroleum refinery, pharmaceutical plant and other manufacturing facility has equipment and piping systems that operate under pressure. In the event of excessive overpressure, equipment or piping failures could result in economic loss to business, environmental contamination, and health and safety risks.
Abstract
Many factors exert an effect on the magnitude of the bursting pressure of rupture disks; therefore up till now there have been no theoretical or even practical principles which make it possible to guarantee disk failure within a range from p to 1.25 p [1] under fixed, specific operating conditions (here p is the maximum permissible pressure).
Abstract
In an earlier paper (2009, “Burst Pressure of Pressurized Cylinders With the Hillside Nozzle,” ASME J. Pressure Vessel Technol., 131(4), p. 041204), an elastic-plastic large deflection analysis method was used to determine the burst pressure and fracture location of hillside cylindrical shell intersections by use of nonlinear finite element analysis. To verify the accuracy of the finite element results, experimental burst tests were carried out by pressurizing test vessels with nozzles to burst.
Abstract
It has been a practice in the process industry to fit rupture disks in pressure equipment to provide means of relieving excess pressure. The disk ensures the safety of life and plant equipment in case of overpressure (Fig. IV-1). A rupture disk is a non-reclosing pressure relief device designed to provide overpressure relief in chemical, petrochemical, and sanitary applications. It can also be defined as a thin metal membrane designed to burst at a certain pressure and temperature to prevent overpressurization of the attached vessel.
Abstract
For straightforward engineering design purposes, the pressure drop of a rupture disc/safety valve unit is related by means of experimentally determined relative discharge reduction coefficients to the flow resistance of the safety valve in the unit. In the case of single phase flow the pressure drop can be calculated on the basis of the liquid or gas/vapour flow discharge coefficients available from the respective suppliers’ catalogues.
Abstract
A rupture disc is a non-reclosing pressure-relief device actuated by inlet static pressure and designed to function by bursting a pressure-containing disc. It separates fluid from a safety relief valve, and thereby prevents leakage through the valve. Rupture discs are made from stainless steel, have a concave shape, and are designed to open at a predetermined pressure.
