Leakage-proof pipe

The utility model relates to the technical field of water heating equipment, in particular to a leakage-proof pipe. The leakage-proof pipe provided by the utility model comprises a pipe body and a leakage-proof ring, wherein one end of the pipe body is a connecting end; the edge of one side of the leakage-proof ring is fixedly connected with the inner side wall of the connecting end to form a fixed ring cavity with the inner side wall of the connecting end; the width of the fixed ring cavity corresponds to the wall thickness of a pipeline to be connected. According to the leakage-proof pipe provided by the utility model, the leakage-proof ring is arranged on the connecting end of the pipe, the pipeline to be connected is fixed in the fixed ring cavity formed by the edge of one side of the leakage-proof ring and the inner side wall of the connecting end, and thus the problem of water leakage at the connection part of the pipe is effectively solved. The leakage-proof pipe provided by the utility model is simple in structure, convenient to mount, excellent in sealing effect and safe and reliable.
