ASME Boiler and Pressure Vessel Code - Wikipedia
Boilers and pressure vessels are sealed vessels used to hold liquids or gases under pressure.Although theoretically they can be made into any shape, pressure vessels are usually made into spheres, cylinders or domes.In other words, most pressure vessels are cylindrical, with a 2:1 semi-elliptical heads or end cap at each end.. Smaller boilers and pressure vessels are made of pipes with end
If the tag is illegible or missing, there will also be a stamped marking on the actual pressure vessel itself with its unique identifier and MAWP. If the MAWP is 15 PSI or below, it's low pressure. Anything higher than that means the boiler is defined as a high pressure boiler.
Jan 04, 2017 · JohnGP is correct, and one can add that a boiler generates steam, while a pressure vessel contains a fluid or gas under pressure, which is a more general definition. The boiler's specific purpose implies that other equipment associated with safely generating steam must be included in the design process, such as water level gauges, blowdowns, etc.
