Abstract

A pressure proof reactor vessel and the method of making such vessel wherein the vessel has a cylindrical one-piece outer wall and a cylindrical one-piece cylindrical inner liner, which liner has a smooth continuous interior surface spaced radially inwardly from the outer wall and concentric thereto. The inner cylindrical wall is formed from a one-piece material with its radial thickness being substantially less than the radial thickness of the outer cylindrical wall. Support means in the form of a spiral is positioned in said space between the cylindrical outer wall and the cylindrical inner liner defining a pathway for the flow of coolant between the outer wall and the inner wall. The support spiral is secured to the outer surface of the one-piece cylindrical inner liner prior to assembling of the inner liner to the outer cylindrical one-piece outer wall.
