Heads Figurs show typical types of closure heads. Elliptical,hemispherical, and torispherical are the most commonly usedhead types. Note that all head types have a straight flange (sf)section, which simplifies welding the head to the adjacentcylindrical shell section. The elliptical and torispherical headshave an indicated head depth (h), which is measured from thestraight flange to the maximum point of curvature on theinside surface.Pardad Petrodanesh CoMechanical Departmentwww.petrodanesh.ir35Eng.Esmail Keynezhad
