The heating pipeline in the heat station is usually buried underground, with a relatively large diameter, and has relatively high requirements for pressure-bearing capacity, corrosion resistance and sealing performance. During the construction process, various problems such as geology and environmental protection need to be considered, so the construction difficulty is relatively large. The heating pipeline in the heat station is a very important part of the heating system and needs to be regularly inspected and maintained to ensure the safe and stable operation of the system. Once problems such as pipeline leakage, corrosion and aging are found, they need to be repaired or replaced in time.

[0003] In the prior art, the heat shrinkable tape is usually used to heat-shrink and insulate the pipeline port at the interface of the heating pipeline. However, under high-temperature conditions, the hot-melt adhesive on the heat shrinkable tape softens, and the heat shrinkable tape fails prematurely in a short period, which cannot ensure the stability of long-term heating protection. Therefore, how to develop a new connection structure for the interface of the heating pipeline has become an urgent problem for those skilled in the art. Content of the Utility Model
