ASME Pressure Vessels

Time to Read: 2m 48s

A pressure vessel is a entirely closed container designed to hold liquids or gases at a higher or lower pressure than the ambient pressure. ASME pressure vessels refers to the US design and operating standards for pressure vessels. The theoretical ideal shape of a pressure vessel (for greatest strength) is a sphere; however, due to the engineering complexities involved, most ASME pressure vessels take the form of a metal cylinder closed with convex endcaps. Pressure vessels must be welded to produce a secure enclosure that can withstand the pressure differential, and the welding or pressure vessels is governed by ASME standards as well.
