A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
The pressure differential is dangerous and many fatal accidents have occurred in the history of pressure vessel development and operation. Consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation. 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.

Famous quotes containing the words pressure and/or vessel:
“I am convinced that our American society will become more and more vulgarized and that it will be fragmentized into contending economic, racial and religious pressure groups lacking in unity and common will, unless we can arrest the disintegration of the family and of community solidarity.”
—Agnes E. Meyer (1887–1970)
“It is plain that there is no separate essence called courage, no cup or cell in the brain, no vessel in the heart containing drops or atoms that make or give this virtue; but it is the right or healthy state of every man, when he is free to do that which is constitutional to him to do.”
—Ralph Waldo Emerson (1803–1882)
