Hemispherical head is the strongest of all heads.Therefore it is used.
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
The ASME Boiler and Pressure Vessel Code details all the various calculations necessary to determine the MAWP of any pressure vessel.
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.
An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
Pumps consist basically of pressure vessels and equipments for supplying compressed air.Concrete is delivered in to the pressure vessel and the vessel sealed tightly.Compressed air is then supplied to the top of the vessel which pushes the concrete out through a pipe connected at the bottom.

A 'ballpeen ' hammer is an engineering hammer with one flat head and one hemispherical head.
it just means that the head on the motor is hemispherical. That means it has a curve to it.
Certified Pressure Vessel
The answer depends on the pressure vessel.
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
When a sailing vessel and a pwc are meeting head on the sailing vessel is the stand on vessel.
hemispherical
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.
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.
A pressure vessel that is not in direct contact with a heating flame
Systolic.
