PROBLEM TO BE SOLVED: To provide a lining steel pipe manufactured not by centrifugal casting but by insert casting.;SOLUTION: A lining steel pipe 1 which is a double tube steel pipe made of different materials and manufactured by insert casting, comprises: a steel pipe 10 to be an outer layer; and a lining 20 to be an inner layer. The steel pipe 10 has interlocking holes 11. The lining 20 is, for example, made of high-chrome cast iron. The lining steel pipe 1 is manufactured by, for example, casting the lining 20 in a manner that places an inner ring inside the steel pipe 10 and injects molten metal into a gap between the steel pipe 10 and the inner ring.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
