Abstract
Abstract A unique cover for a fluid pressure chamber having (1) a member that is subject to corrosion, (2) a corrosive resistant metal sheet in contact with a surface of the member that forms an inner wall of the chamber, (3) a corrosive resistant metal tube that forms a passageway extending through the member and the corrosive resistant sheet into the chamber and, (4) tapered stepped portions on the inner end of the tube for physically engaging the sheet to provide a noncorrosive fluidtight joint between the corrosive resistant metal sheet and tube.

A cover for a fluid pressure chamber, comprising a member that is of a material that is subject to corrosion, a sheet of corrosive resistant metal covering a surface of said member that forms an inner wall of said chamber to protect the inner wall of said member from the corrosive action of a corrosive fluid, said member having at least one corrosive resistant metal tube forming a corrosive resistant passageway therein that extends between an outer wall surface of said member through said member and through a wall forming an aperture in said corrosive resistant sheet and then into contact with said sheet by means of tapered stepped portions on the inner end of the tube to thereby provide a noncorrosive fluidtight joint between the corrosive resistant metal sheet and tube.
