Embodiment 1
[0031] to combine figure 1 , the present invention is a steel-aluminum composite pipe, which is a bimetallic composite pipe, comprising a seamless steel pipe 1 and an aluminum pipe 2 poured outside the seamless steel pipe 1 . A threaded hole 3 penetrating through the side wall of the seamless steel pipe 1 is provided on the pipe wall of the seamless steel pipe 1 . The axial direction of the threaded hole 3 is arranged along the radial direction of the seamless steel pipe 1 . Threads are provided on the side walls of the threaded holes 3 . The inner wall of the aluminum tube 2 is filled with the threaded hole 3 . A screw 4 is welded to the outer wall of the seamless steel pipe 1 . Screw teeth are provided on the outer surface of the screw 4 . The screw 4 penetrates into the aluminum tube 2 . In this embodiment, there is no specific limitation on the number and positions of the threaded holes 3 and the screws 4 .
