Pressure vessels’ purpose is to hold toxic or harmless gases or liquids at certain pressures. The temperatures of operation of these pressure vessel systems differ. They also come in different shapes and sizes with a wide range of applications usage. The most demanded geometries for production are that of conical, spherical and cylindrical. Supposing that a pressure vessel cannot cope with the pressure, leading to deformation or cracks that can cause contamination to the surrounding area where it is placed and even to the people nearby. Therefore various codes, regulations and standards have been put into place, depending on the continent, country, or market specifications to ensure maximum safety. These codes ensure that compulsory design terms and non-mandatory steps for how the material should be used for pressure vessel construction, design, audit, testing, exploitation, etc. A shaped head and body are integral parts of any pressure vessel design.
