Pressure vessels are designed to hold their contents (usually a liquid or gas) at a pressure above 15 psi or 1 bar. As there is a strong inherent danger of a sudden discharge of pressure, pressure vessel design and manufacturing is strictly controlled by jurisdictional regulations and design codes. In North America, the American Society of Mechanical Engineers Boiler and Pressure Vessel Code is universally applied. Pressure vessels are fabricated to function as filtration vessels, ammonia tanks, scrubbers, separators, knock out drums, air receivers, quench columns, distillation columns, pilot vessels, condensers, storage tanks, scavenger vessels, blowback surge tanks, catalyst holding tanks, slug catchers, flash drums, strippers, recycle drums, strainer vessels, CLAD Vessels, Reaction furnaces, Incinerators, oxidizers, crystallizers..etc According to ASME VIII Div 1,CSA B51, FEA, PED/CE, SELO For various applications like high pressure, high temperature (refractory lined-directly fired), cryogenic, sour service, corrosive service etc.
