Design Of Pressure Vessel : A Comparative Study Between Code Vs Analysis Approach

Abstract

Pressure vessels are most widely used in industrial machinery contributing as main components for proper functioning of any mechanical system. Primitive purpose of these containers is storage. This includes preservation of fluids including liquids and gases with in specific safety conditions. When these gases are stored in adequate arrangements at required temperature and pressure conditions accidents are avoided and more safety is ensured. This reason has lead to common use of pressure vessels within different practices of any social network. Use of pressure vessels in nuclear sector is very important. Application of these mechanical components in nuclear field has brought tremendous change in lives of nations over past few decades. Research and developments of countries is based majorly on adequate use of pressure vessels. Ranging from simple cruises to ballistics and even space launch vehicles ,the main driving applications are based on pressure vessels. Pressure vessels serve as potential source for storing energy and therefore these have safety issues. During the start of twentieth century several accidents occurred and the world realised the safety risks involved with improper use of pressure vessels. These catastrophic accidents resulted in heavy loss of lives. Manufactures immediately felt the need to regularize the criteria for designing and fabrication of pressure vessels. Some of these interested parties jointly appealed to American Society of Mechanical Engineers for their assistance to formulate rules. The intention was to formulate standard specifications for steam boilers and pressure vessels. The very first set of codes for pressure vessels was established in 1925 with the title of “Rules for construction of 7 Pressure Vessels”. Nowadays all pressure vessels are designed in the United States in accordance with ASME Section VIII.
