PART 1 (35 MARKS) A pressure vessel is a specialized container designed to hold gases or liquids at significantly high pressures from the ambient pressure. These vessels play a critical role in numerous industrial processes, where containing substances at elevated pressures is essential for chemical reactions, material processing, storage, and transportation. The pressure vessels are engineered with specific materials and construction techniques to safely contain substances under high pressures and varying temperatures without deformation or rupture. Their design and construction adhere to stringent standards and regulations to ensure safety, reliability, and performance. Their fabrication involves intricate processes and stringent quality control measures to ensure structural integrity and operational safety. Question 1: Characteristics of Metals and Alloys (9 marks) a. Name THREE common metals or alloys commonly used in the fabrication of pressure vessels. b. Discuss their essential characteristics of the metal for pressure vessel construction. Highlight why these properties are crucial for a pressure vessel.
