Connecting conduit

Abstract

This is a connecting conduit (100). The connecting conduit (100) includes a first connecting pipe (10) and a second connecting pipe (20). The edge of the pipe opening at one end of the first connecting pipe (10) is formed as a connecting surface (11), a communication hole (22) is drilled in the pipe wall of the second connecting pipe (20), and the second connecting pipe (20) is provided with a connecting engagement surface (21) at the outer circumference of the communication hole (22). The shapes of the connecting surface (11) and the connecting engagement surface (21) are matched to each other, and the connecting surface (11) is welded in close contact with the connecting engagement surface (21) so that the first connecting pipe (10) and the second connecting pipe (20) are connected and communicate with each other. The materials of the first connecting pipe (10) and the second connecting pipe (20) are the same.
