摘要
A method of manufacturing an internally clad tubular product employing a tubular host such as steel, including the steps of plating the internal surface of the tubular host with a low melting point bonding metal alloy, inserting a tubular clad member, such as of nickel base alloy, into the plated tubular host, circumferentially welding one end of the cladding member to one end of the host member directly and welding the other ends in such a manner as to incorporate a metallic gas reservoir, thus forming a subassembly, evacuating the annular space formed in the subassembly between the exterior of the cladding member and the interior of the tubular host of water vapor and oxygen, heating the subassembly to about 1650° to 2000° F. thereby melting the bonding metal alloy, and hot rolling the heated subassembly to metallically bond the cladding member to the tubular host by means of the mechanism of liquid interface diffusion bonding.
