Patent ID: 11826805

Abstract:
A method of producing a clad billet includes inserting a solid carbon or low-alloy steel (CS) material into a hollow interior of the slightly larger diameter (CRA) cylinder so that a standoff gap is provided between an outer surface of the (CS) material and the inner diameter of the (CRA) cylinder; providing an explosive material around the (CRA) cylinder; detonating the explosive material to collapse at least the inner diameter of the corrosion resistant alloy cylinder onto the outer surface of the solid carbon or low-alloy steel material and eliminate the standoff gap, creating at least a partial metallurgical bond at an interface with the outer surface and resulting in a composite billet assembly; and extruding the composite billet assembly to reduce its size and form the clad billet having a metallurgical bond between the (CS) material and the (CRA) cylinder.
