Pressure VesselA pressure vessel is
defined as a vessel in which the pressure is obtained from an indirect
source or by the application of heat from an indirect source or a direct
source. The vessel proper terminates at: (a) the first circumferential joint
for welded end connections; (b) the face of the first flange in bolted flange
connections; or (c) the first threaded joint in threaded connections."
Pressure vessels include but are not limited to compressed gas storage tanks
(i.e., air, oxygen, nitrogen tanks, etc.), anhydrous ammonia tanks, hydro
pneumatic tanks, autoclaves, hot water storage tanks, chemical reactors and
refrigerant vessels, designed for a pressure greater than 15 psi and a volume
greater than 5 cubic feet in volume or one and one-half cubic feet in volume
with a pressure greater than 600 psi.



 Pressure vessels most
often contain fluids, vapors, or gases at pressure levels greater than that of
atmospheric pressure. Pressure vessels contain a wide variety of substances
used for various industrial applications including chemical; pharmaceutical;
food and beverage; oil and fuel; and plastic industries. The substance
contained and the industrial application of the pressure vessel determines such
design components as vessel material, size, shape, temperature, and pressure
level.
