SYSTEMS AND METHODS FOR IMPROVED PRESSURE VESSELS

摘要

Systems and methods are described herein for manufacturing a pressure vessel component. The pressure vessel component may be made from a metal that is cast to produce a gross pressure vessel component. Casting the metal may comprise sintering the metal followed by a hot isostatic press (HIP) process. In other embodiments, casting the metal may comprise pouring molten metal into a mold. Portions of the gross pressure vessel component may have an increased thickness located at predetermined positions on the gross pressure vessel component. These portions may include bosses or other designed features intended for the finalized pressure vessel component. The gross pressure vessel may be indexed to select the portions, and these selected portions may then be machined to produce the final pressure vessel component.
