The connection of branch pipes to pressure vessels raises special stress problems. The problems of avoiding an abrupt change of contour snd of enabling examination of the weld can be solved by the arrangement in the aperture for the branch of a ring of special shape whose outer edge is equal in thickness to that of the wall of the vessel end which is butt welded to the surrounding wall. The thickness of the ring increases smoothly from its outer edge to a value around its inner edge at a calculated ratio (stress concentration through piercing the vessel). The ring provides at or near its inner periphery a flange to be butt welded to the branch pipe. (auth)
