A
pressure vessel is a container for containing liquids or gases at a
pressure which is substantially different from ambient pressure.

The
pressure difference is dangerous, and there are fatal accidents in
the history of pressure vessel development and operation have
occurred. As a result, are the design of pressure vessels,
manufacture and operation by the supported by regulated engineer regulatory authorities. For these reasons, the definition of a
pressure vessel of a country varies but includes parameters such as
maximum working pressure for safety and temperature and is equipped
with a safety factor, accuracy at Corrosion, minimum temperature (for
fragile fractures) and worked destructive tests such as ultrasonic
testing, radiography and compression, usually with water, also known
as hydraulic testing, but could be tested with Air or other gas. The
preferred test is the hydrostatic test because it is much safer test
method because it releases much less energy when the break occurs
(water does not increase rapidly in volume, while depressurization
Fast occurs, as opposed to gases such as air, that is, no explosive
gas).
In
the United States, as in many other countries, it is the law that
ships on a certain size and pressure (15 PSI) to build to the code in
the US code is the ASME on boilers and Vessel Pressure Code BPVC)
These vessels also require an authorized inspector to build on each
new vessel and each vessel has a name tag with relevant information
about the vessel that the maximum permissible working pressure,
maximum temperature, design metal temperature Date, its registration
number (by the National Office) and the ASME official stamp for
pressure vessel (U-buffer), so that the traceability of the vessels
and officially code ship ASME.
