The present invention discloses a non-stop steam pipe steam patch structure for the steam pipe steam leakage point (1), (3) repair, repair of the structure reinforcement is provided pipe (2), the reinforcement pipe (2) of the cavity and the steam pipe (1) steam leakage site for some appearance coincides; reinforcement of the pipe (2) along its axis coincides with the cross-sectional plane is divided into two. By adopting the technical scheme, so that the steam pipe after the leak can not shutdown, stop gas leakage can be directly Steam site repair work, reducing the pipeline due to a leak must be shutdown to stop gas processing downtime, improve furnace for leaking steam pipe by lowering the operating rate, but also greatly ease the steam pipe sick job situation.
