Pressure Vessel Heat Exchanger
The pressure have occurred in the
history of pressure vessel development and operation.
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
For these reasons, the definition of a pressure vessel varies from country to country, but involves parameters such as maximum safe operating pressure and temperature.
Consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation.
