[0002] The thermal pipeline starts from the boiler room, direct-fired machine room, heating center, etc. The heating pipeline from the heat source to the thermal entrance of the building is called the thermal pipeline. With the continuous development of the times, people's living standards have gradually improved, the demand for heating has gradually increased, and the demand for thermal pipelines has also increased accordingly.

[0003] At present, there are still some problems in the process of patching the pipe mouth of the thermal pipeline. That is, usually the personnel use a cutting machine to cut off the damaged outer part as a whole, and then place a sealing ring with the same length as the cut off between the thermal pipelines, and then use welding to seal the pipe mouth. However, when the sealing ring is placed between the thermal pipelines, there is no position restriction and positioning work on it, which affects the welding work of the personnel and affects the axis between them not being on a more precise axis line. For this reason, we propose a thermal pipeline pipe mouth sealing structure to solve the above problems. Utility Model Content
