Aug 25, 2020 · These heads possess a flatter or lower profile, which makes them ideal for pressure vessels that have a height restriction. The F&D heads are shallower than 2:1 heads, which means they need not be dished as much and as deep as a 2:1 head. Based on design pressure and vessel size, ASME F&D heads are thicker than 2:1 elliptical heads.
