How to solve the problem that the thickness of the heat-insulating layer of the raised area is consistent with that of the heat-insulating layer of the straight pipe section of the pipeline is a difficult problem in heat-insulating construction of the flexible interface pipeline. Currently, there are two main processing methods: 1) the method adopts a straight heat preservation mode of an interface area to increase the thickness of the whole heat preservation layer of the whole pipeline, preferentially ensures that the thickness of the heat preservation layer of the socket area meets the requirement, namely the thickness of the heat preservation layer of the straight pipe section of the pipeline is increased to meet the heat preservation requirement of the whole pipeline, and greatly increases the cost of heat preservation materials of the pipeline. 2) The thickness of the heat-insulating layer in the interface area is increased by only carrying out special treatment on the interface area without directly increasing the thickness of the heat-insulating layer, adopting a plurality of processes, adding annular heightening accessories to the interface area, and then coating the electric melting sleeve. This approach, however, increases construction complexity and increases the cost of insulation in the interface area.
In conclusion, flaring the two ends of the outer sheath layer is the most convenient and rapid method for heat preservation construction of the on-site interface area of the flexible interface heat supply pipeline at present.
