I guess it depends on whether it's sealed or not.
If it's open to the atmosphere how can it be under pressure ?
If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
A receiver is normally some kind of pressure vessel the pressure inside the vessel/tank became too high the structure could fail"poss with dire consequenses".Therfore a safety valve is fitted to release internal pressure at a pre set figure set below the critical or dangerous pressure level that the receiver is designed for.This is usually reffered to as the SWP,or safe working pressure.

The ASME Boiler and Pressure Vessel Code details all the various calculations necessary to determine the MAWP of any pressure vessel.
To absorb the expansion volume of the water in the circuit after it is heated. This in turn stops the pressure rising to excessive levels which could cause system damage.An expansion vessel is a small tank that is used to protect water heating systems from excessive amounts of pressure. They can also be used to protect the cooling systems of internal combustion engines.
An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
A tank is designed to hold the maximum hydrostatic pressure at the base -- based on the depth of the tank, the density of the material it holds, and maximum atmospheric pressure (with added margin for safety). A tank wall may be constructed with 'thicker' material at the base and 'thinner' material at the top, to save cost. The top of the tank need only support its own weight (plus safety margin). A pressure vessel must withstand the rated pressure at all points around the surface of the vessel.
Certified Pressure Vessel
A test pressure whcih is used to perform hydro test is known as hydro test pressure, besically the hydro test pressure is more then the design pressure of pipe, tank, pressure vessel ..................
The answer depends on the pressure vessel.
approximately 0.8 bar

The main purpose of a pressure vessel is to hold gases or liquids at a pressure inside a container different to the pressure outside of the pressure vessel. Usually pressure vessels are made from steel.
check your vessel
A pressure vessel that is not in direct contact with a heating flame
Systolic.
As blood enters the capillary bed on the arteriole end, the blood pressure in the capillary vessel is greater than the osmotic pressure of the blood in the vessel. The net result is that fluid moves from the vessel to the body tissue.At the middle of the capillary bed, blood pressure in the vessel equals the osmotic pressure of the blood in the vessel. The net result is that fluid passes equally between the capillary vessel and the body tissue. Gasses, nutrients, and wastes are also exchanged at this point.On the venue end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
