    • Clad pipe having an inner pipe and an outer pipe metallurgically bonded to each other is manufactured by a process comprising the steps of: (a) preparing an inner pipe and an outer pipe made of different metallic materials, the outer pipe having an inner diameter larger than the outer diameter of the inner pipe; (b) forming an Ni-B layer by electroplating or electroless plating on the surface of one of the pipes facing the other pipe when the two pipes are assembled, the Ni-B layer having a thickness of 2-100 .mu.m and consisting essentially, on a weight basis, of B: 0.5%-7%, Fe: 0%-30%, P: 0%-7%, and a balance of Ni and inevitable impurities; (c) assembling the two pipes by inserting the inner pipe into the outer pipe; (d) subjecting the assembled pipes to cold working for reduction in diameter to such a degree that the outer diameter of the inner pipe is reduced by from 0.5% to 10% to form raw clad pipe in which the inner and outer pipes are in contact; and (e) subjecting the raw clad pipe to heat treatment in the temperature range of 1050.degree.-1250.degree. C. for a time sufficient to metallurgically bond the inner and outer pipes by diffusion bonding.
    • 通过包括以下步骤的方法制造具有彼此冶金结合的内管和外管的包层管:(a)制备由不同金属材料制成的内管和外管,所述外管的内径较大 比内管的外径大; (b)当组装两根管时,在面对另一根管的一个管的表面上通过电镀或无电镀形成Ni-B层,厚度为2-100μm的Ni-B层基本上 以重量计,B:0.5%-7%,Fe:0%-30%,P:0%-7%,余量为Ni和不可避免的杂质; (c)通过将内管插入外管来组装两个管; (d)对所组装的管进行冷加工以减小直径,使得内管的外径减小0.5%至10%,以形成内管和外管接触的生坯复合管 ; (e)在1050〜-1250℃的温度范围内对原料复合管进行热处理足够的时间,以通过扩散粘合冶金地结合内管和外管。
