    摘要: In one embodiment, a tubular assembly is provided, comprising a first iron based tubular having a first non-cladded inner surface; and a second iron based tubular having a second non-cladded inner surface, wherein the first tubular is connected to the second tubular using a non-iron based bonding material. Preferably, the non-iron based bonding material has a lower crack growth rate than the iron based tubulars.
