Taper detail for hemispherical head to shell welding

For example, if you have calculated your shell thickness under internal pressure and obtained 12 mm, your hemispherical head thickness also will be approximately 6 mm. The inside depth of your hemispherical head will be one-half of head inside diameter (h = D/2). Dimensional Inspection of Pressure Vessel Dished Heads.

The hemispherical head has a simple radial geometry: the depth of the head is half the diameter. With a 47" ID, the required wall thickness is 0.2474", about half the thickness of the shell. Because the head is thinner than the shell, a standard code 3:1 taper is used on the transition.

Pressure Vessels - processdesign

Mar 01, 2015 · Pressure vessels with a wall-thickness:diameter ratio of less than 1:10 can be classified as thin-walled, and the rest, thick-walled (Towler and Sinnott, 2013). Pressure vessels typically consist of a cylindrical shell and elliptical or hemispherical heads at the ends (Peters and Timmerhaus, 2003).

Hemispherical head ASME Code Section VIII, Division 1

Since the hemispherical head therefore includes a Category A joint at all times, the ASME Code never considers it as a seamless, but always as a welded part. This also applies to hemispherical heads manufactured from seamless plates. Thus the requirements of UW-12(d) for seamless vessel sections must not be used.
