Definition - What does Pressure Vessel mean?
Pressure vessel is a container used to store and transmit gas and other liquids at a significant pressure. The vessel is either spherical or cylindrical in shape. It can be categorized according to its construction or dimensions. The vessels with end construction include an open end and a closed end whereas vessels with different dimensions are said to have a thick or thin shell. The vessels that have thin shells are used in boilers and pipes while the vessels that have thick shells are used in pressure cylinder and tank gun barrels.
Petropedia explains Pressure Vessel
Pressure Vessels are specially designed to store fluids at high temperatures thus they can tolerate pressures above 15 psi. These vessels are regulated by engineering authorities to avoid fatal accidents at the sites. During their manufacture, they undergo non-destructive testing, radiography, and ultrasonic testing to get an official stamp of ASME (American society of mechanical engineers). The vessels have a broad range of applications thus are used in both the public and private sectors. One of the unique forms of the Pressure Vessel is that it is used as a passenger cabin of the airliner. However, it is important to check the vessels carefully as leakage can cause rupture failures.
