[0025] Figure 1 This is a flow chart of the pipeline insulation construction process in the present invention, please refer to Figure 1 As shown, a preferred embodiment is shown, and a pipeline insulation construction process is shown, including:

[0026] S1. Pipeline surface treatment: grinding and polishing the pipeline surface, and then pre-circling a number of fixed-point heating areas on the pipeline surface; the fixed-point heating areas are distributed along the axial direction of the pipeline, and two adjacent fixed-point heating areas can be located on the same side or different sides of the pipeline.

[0027] S2. Installation of the heating plate. The shape of the heating plate is customized in advance according to the shape of the outer wall of the pipeline, and the heating plate is installed on the surface of the fixed heating area. The heating plate can be pre-fixed on the outer wall of the pipeline by gluing. The heating plate can be connected to an external controller. Each heating plate can be controlled to work separately through the controller, and the heating temperature of the heating plate in each area can be monitored, and the heating temperature of the heating plate can be controlled as needed.

[0028] S3. Insulation layer production: The size and shape of the insulation layer are pre-customized according to the size and curved shape of the pipeline, and wire holes are opened on the surface of the insulation layer; the insulation layer is installed on the outer wall of the pipeline and covers the heating plate. The wire holes set on the insulation layer are convenient for the power cord of the heating plate to pass through. The setting of the wire holes will not affect the overall insulation effect of the insulation layer.

[0029] S4. Install the insulation layer. Put the insulation layer on the surface of the pipe and the heating plate, and seal the surface of the insulation layer. The insulation layer can be set to keep the heat in order to prevent the liquid inside the pipe from freezing due to the external low temperature.

[0030] S5. Install the protective layer, and set the protective layer on the surface of the insulation layer. The protective layer is used to protect the insulation layer, which can prevent the insulation layer from being exposed to external sunlight or wind, and can also prevent the insulation layer from being damaged by external collisions.

[0031] Further, as a preferred embodiment, in S1, the surface of the pipeline is polished and polished, and anti-corrosion paint and a waterproof layer need to be applied on the surface of the pipeline. The anti-corrosion paint can prevent the pipeline surface from being corroded by liquid or acidic and alkaline substances, thereby protecting the pipeline and extending the service life of the pipeline.

[0032] Further, as a preferred embodiment, in S2, after the heating plate is installed, a heat-conducting wire is wound on the surface of the pipe, the heat-conducting wire is spirally distributed on the outer wall of the pipe, and the two ends of the heat-conducting wire are connected to two adjacent heating plates. The heat-conducting wire has good thermal conductivity and can quickly transfer the heat generated by the heating plate to the surface of the pipe to achieve heating treatment of the pipe, while the heating plate itself can centrally heat the surface area of ​​the pipe, and the heating temperature is controllable, will not damage the pipe, and can always keep the liquid inside the pipe flowing normally without freezing.

[0033] Furthermore, as a preferred embodiment, after the heat conducting wire is installed, a heat insulating layer needs to be installed, and the heat insulating layer covers the surface of the heat conducting wire and the heating plate away from the pipe. The heat insulating layer can prevent the heating plate and the heat conducting wire from contacting the heat insulating layer, thereby protecting the heat insulating layer.

[0034] Furthermore, as a preferred embodiment, the thermal insulation layer is made of polyurethane material, which itself has good heat insulation and flame retardancy effects. Combined with the setting of the heating plate and the thermal wire, it can achieve better heating and thermal insulation effects. Through the setting of the thermal insulation layer, the heat generated by the heating plate will diffuse outward more slowly, which can achieve long-term heat preservation and improve the heating effect.

[0035] Furthermore, as a preferred embodiment, the insulation layer is installed on the surface of the pipe in sections. After the insulation layer is installed, two adjacent insulation layers are fixed by gluing, and then the insulation layers are wrapped with film for packaging. The connection between the insulation layers is not limited to gluing, and can also be connected together by other means. By wrapping the film, heat loss can be further reduced, and the insulation effect can be further improved.

[0036] Further, as a preferred embodiment, the protective layer is made of stainless steel and is installed on the outer surface of the insulation layer in sections. After installation, two adjacent protective layers are welded together. The protective layer is formed by curling a thin sheet of stainless steel. The specific thickness can be selected as needed. The two adjacent protective layers can also be fixed by gluing. A waterproof layer needs to be provided at the connection.

[0037] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
