[0033] A convex edge 21 is provided on the connection surface of the mounting housing 2, and the sealing gasket 3 is nested inside the area formed by the convex edge 21 to prevent the sealing gasket 3 from shifting during use;

[0034] Both sides of the installation shell 2 are provided with connecting ears 22, and a plurality of mounting holes 221 are evenly formed on the connecting ears 22. The fasteners 4 are connected in the mounting holes 221, and the fasteners 4 fix the two sets of installation shells 2 through the mounting holes 221 formed on the connecting ears 22.

[0035] A foaming chamber 6 is formed between the two groups of the mounting shells 2 and the two groups of the flange bodies 1. The foaming chamber 6 is filled with foamed plastic, which plays a buffering role to prevent collision between the mounting shells 2 and the flange bodies 1 due to external impact.

[0036] The installation shell 2 has a heating chamber 7, a vacuum chamber 8, a thermal insulation layer 9 and a heat insulating layer 10 in sequence inside. The heating chamber 7 is wrapped around the outside of the foaming chamber 6. The vacuum chamber 8 is located between the heating chamber 7 and the thermal insulation layer 9. The thermal insulation layer 9 is located outside the vacuum chamber 8. The thermal insulation layer 10 wraps the thermal insulation layer 9. The innermost heating chamber 7 provides temperature for the pipeline flange. The vacuum chamber 8 outside the heating chamber 7 reduces the heat exchange outside the heating chamber 7.

[0037] A plurality of heating rods 71 ​​are evenly arranged in a ring shape in the heating chamber 7. The plurality of heating rods 71 ​​are connected by wires.

[0041] Working principle: First, install the sealing gasket 3 in the area of ​​the mounting shell 2 with the convex edge 21 to ensure that the sealing gasket 3 will not shift during use. Secondly, use multiple fasteners 4 to pass through the multiple mounting holes 221 on the connecting ear 22 to fix the two sets of mounting shells 2 on the flange mounting ring 5. Furthermore, the thickness of the sealing gasket 3 is greater than the rear end of the convex edge 21 to ensure that the sealing gasket 3 is tightly fitted with the flange mounting ring 5 during use and has good sealing performance. Then, the foaming bin 6 formed between the mounting shell 2 and the two sets of flange bodies 1 is installed. There is foamed plastic in the foaming bin 6. The flange body 1 is protected. Finally, the interior of the installation shell 2 is divided into a heating chamber 7, a vacuum chamber 8, a thermal insulation layer 9 and a heat insulating layer 10 in sequence. The heating rod 71 in the innermost heating chamber 7 is used to heat the pipe flange to provide temperature.

The thermal insulation layer 9 and the heat insulating layer 10 cooperate with each other to prevent heat exchange between the inside and outside of the installation shell 2, thereby solving the problem that the pipe flange is easily deformed due to heat loss in a low temperature environment.
