ABSTRACT OF THE DISCLOSURE A powder-metallurgy method and assembly for producing tubular product having at least one surface and preferably an interior surface thereof clad with an alloy different from and preferably more resistant to destructive media than the material from which the remainder of the tubing is constructed. An assembly is constructed of a metal tubing having an internal surface to be clad and a tubular insert mounted generally axially within the tubing in spaced-apart relation to the internal surface thereof, which provides a generally annular cavity between the internal surface of the tubing and the tubular insert. This cavity is filing with metal particles of a composition to be clad on the tubing internal surface. The cavity is sealed and the assembly is heated to an elevated temperature at which it is extruded to compact metal particles introduced to the cavity to substantially full density and metallurgically bond the particles to the internal surface to provide a desired destructive-media resistant cladding.
