The design (as indicated on line 14, Remarks) conforms to ASME Rules, Section I of ASME BOILER ANDPRESSURE VESSEL CODE. P-4 ID No. Page of
The most common head shapes are: Hemispherical head. A sphere is the ideal shape for a head, because the pressure in the vessel is divided equally across the surface of the head. The radius (r) of the head equals the radius of the cylindrical part of the vessel. Ellipsoidal head. This is also called an elliptical head.
The ASME VIII-1 calculated design pressure for the cylinder is 420 psi. Four commonly used head types on vessels are Hemispherical (Hemi), Semi Elliptical (SE), Flanged and Dished (F&D) and Flat. For this article, each of the four heads is attached to the cylinder, with diameters matching on the ID.
