центральный сегмент (составных днищ сосудов и аппаратов большого размера =insert plate; Vessel heads are usually formed with one plate section. But when the head diameter becomes too large and you cannot use just one plate section, the head is fabricated in orange peel sections. The orange peel sections meet at a "circular plate" at the center of the head. That circular plate is referred by others as the "dollar plate". Another word for an insert plate which is much thicker than the local shell that it is being inserted in and butt welded to. They are used to thicken the shell locally, very often around nozzle necks when sufficient reinforcement can't be achieved by a repad, whether it's for area replacement of the nozzle or to help counter other mechanical loads such as pipe loads.
