PD 5500 is a British Standard that provides guidelines and requirements for the design and construction of pressure vessels and heat exchangers made from metallic materials. It covers various aspects of pressure vessel design, including material selection, design methods, fabrication, inspection, and testing to ensure safety and reliability in their operation. The standard is widely used in industries such as chemical processing, oil and gas, power generation, and many others where equipment must safely withstand high pressures and temperatures.
