2019-11-9 · Theoretically, a spherical pressure vessel has approximately twice the strength of a cylindrical pressure vessel with the same wall thickness, and is the ideal shape to hold internal pressure. However, a spherical shape is difficult to manufacture, and therefore more expensive, so most pressure vessels are cylindrical with 2:1 semi-elliptical heads or end caps on each end.

Heat transfer equipment may be designated by type or function it performs, such as chiller, condenser, cooler reboiler, etc. The choice of shell and tube type is determined chiefly by factors such as the need for the provision for differential movement between shell and tubes, the design pressure, the design temperature, and the fouling nature of the fluids rather than the function.
2001-11-30 · thickness, (b) increase the wall thickness of the nozzle, or (c) use a combination of extra shell and nozzle thickness. The Code procedure is to relocate the removed material to an area within an effective boundary around the opening. Figure 9.1 shows the steps necessary to reinforce an opening in a pressure vessel.
I have some confusion on minimum required thickness of pressure vessel as per ug-16(b), which state that the minimum required thickness for unfired steam boiler and compressed air service or water service is 6 mm and 2.5 mm. But my vessel is used for curde oil service. so, which one I want to take as minimum required thickness as per code.

2019-12-12 · The Shell Thickness calculation page is to calculate the wall thickness of a cylinder, cone and sphere under pressure without holes. The calculation does not take into account the extra stress around holes for nozzles and is therefore a basic strength calculation. Calculation codes are ASME, Dutch Rules and the EN Euronorm.
A 0.7752 inch minimum thickness multiplied by a 15 percent tolerance or 115 becomes 0.7752 x 1.15. This equals 0.89147 inches, or almost 0.9 inch minimum pipe wall thickness. If a safety factor of two was required, the minimum thickness of 0.7752 x 2 would give a minimum wall thickness of 1.5504 inches.

From a model boiler perspective increasing the shell thickness from say 20swg (0.036"or 0.9mm) up to 16swg (0.064" or 1.625mm) would make very little difference other than taking a minute or so longer to reach working pressure. Keep happy. Sandy. :D
