[0029] Referring to Figures 1-3 , an embodiment provided by the present utility model: a heat-resistant steel skeleton polyethylene plastic composite pipe, including a polyethylene composite pipe 1, a fixed disc 2 is connected to the outer wall of the polyethylene composite pipe 1, a heat-resistant steel bar 3 is fixedly installed on the fixed disc 2, a through groove 4 is arranged inside the fixed disc 2, a heat-resistant steel skeleton 5 is installed on the inner wall of the polyethylene composite pipe 1, a high-density polyethylene layer 6 is arranged on the outer layer of the polyethylene composite pipe 1, an alloy steel frame net 7 is connected to one side of the high-density polyethylene layer 6, a heat preservation layer 8 is arranged at the bottom of the alloy steel frame net 7, a polyethylene resin layer 9 is arranged below the heat preservation layer 8, a rock wool board layer 10 is connected to one side of the polyethylene resin layer 9, and a low-density polyethylene layer 11 is arranged at the bottom of the rock wool board layer 10.

[0030] In the present utility model, the fixed disc 2 is fixedly installed on the outer wall of the polyethylene composite pipe 1. The fixed disc 2 is in the shape of a disc, and the number of the fixed discs 2 is two. The two fixed discs 2 are respectively located at both ends of the polyethylene composite pipe 1, playing a role of stabilizing and supporting. They not only enhance the structural strength of the polyethylene composite pipe 1, but also provide reliable support points during the installation and use process.

[0031] The disc-shaped design of the fixed disc 2 is not only beautiful and generous, but also has a large contact area, thereby increasing the friction with the outer wall of the polyethylene composite pipe 1 and ensuring the tight connection between the fixed disc 2 and the polyethylene composite pipe 1.

[0032] Furthermore, the through slots 4 are opened inside the fixed disc 2. The number of the through slots 4 is several. The heat-resistant steel bars 3 are welded between the through slots 4. The number of the heat-resistant steel bars 3 is several. The heat-resistant steel bars 3 are evenly distributed inside the fixed disc 2 to form a stable support structure, effectively improving the overall strength and high-temperature resistance of the fixed disc 2.

[0033] Furthermore, the heat-resistant steel skeleton 5 is fixedly connected to the inner wall of the polyethylene composite pipe 1. The high-density polyethylene layer 6 and the low-density polyethylene layer 11 are fixedly connected to the outer layer of the polyethylene composite pipe 1. The widths of the high-density polyethylene layer 6 and the low-density polyethylene layer 11 are the same. The low-density polyethylene layer 11 is connected to the heat-resistant steel skeleton 5, thus constituting a stable and efficient thermal insulation layer, enabling the polyethylene composite pipe 1 to still maintain excellent performance in extreme temperature environments.

[0034] The heat-resistant steel skeleton 5 not only enhances the structural strength of the polyethylene composite pipe 1 but also improves its impact resistance, enabling it to operate stably in various complex environments.

[0035] Furthermore, the alloy steel frame net 7 is fixedly connected to one side of the high-density polyethylene layer 6. The rock wool board layer 10 is fixedly connected to one side of the low-density polyethylene layer 11. The widths of the alloy steel frame net 7 and the rock wool board layer 10 are the same. The combination of the high-density polyethylene layer 6 and the alloy steel frame net 7 not only enhances the mechanical properties of the overall component but also provides excellent moisture-proof performance, avoiding the erosion of water vapor. At the same time, the wear resistance and corrosion resistance of the high-density polyethylene layer 6 also extend the service life of the component.

[0036] The low-density polyethylene layer 11 plays a good role in heat preservation and insulation. Its unique closed-cell structure effectively blocks the transfer of heat, resulting in a significant improvement in the heat preservation performance of the entire component. In addition, the light weight characteristic of the low-density polyethylene layer 11 also reduces the weight of the overall component, facilitating installation and transportation.

[0037] Furthermore, the heat preservation layer 8 is fixedly connected to one side of the alloy steel frame net 7. The polyethylene resin layer 9 is fixedly connected to one side of the rock wool board layer 10. The heat preservation layer 8 is fixedly connected to the polyethylene resin layer 9. The surface of the polyethylene resin layer 9 is smooth and has a certain toughness, which can effectively prevent external factors from damaging the heat preservation layer 8. At the same time, the polyethylene resin layer 9 also has excellent weather resistance and anti-aging performance, and can maintain the stability of its appearance and performance for a long time.

[0038] In addition, as a high-quality heat preservation material, the rock wool board layer 10 contains a large number of small air pockets inside, and these air pockets can effectively slow down the heat conduction speed and improve the heat preservation effect.

[0039] Working principle and its usage process:

[0040] The heat-resistant steel skeleton 5 plays a role in supporting and strengthening on the inner wall of the polyethylene composite pipe 1, improving the compressive capacity and impact resistance of the whole pipeline. The high-density polyethylene layer 6 and the low-density polyethylene layer 11 respectively provide good corrosion resistance and wear resistance, extending the service life of the pipeline. At the same time, the fixed connection of the high-density polyethylene layer 6 and the low-density polyethylene layer 11 makes the structure of the pipeline more stable and not easy to deform or be damaged.

[0041] In terms of working principle, this heat-resistant steel skeleton polyethylene plastic composite pipe utilizes the excellent properties of each component part to achieve stable operation in a high-temperature environment. When the pipeline is subjected to external pressure or temperature changes, the heat-resistant steel skeleton 5 can effectively disperse and resist these pressures, while the high-density polyethylene layer 6 and the low-density polyethylene layer 11 can effectively prevent the pipeline from being corroded or worn. At the same time, the fixed connection of the alloy steel frame net 7 and the rock wool board layer 10 further enhances the strength and heat insulation performance of the pipeline, enabling the pipeline to still maintain a good working state in a high-temperature environment.

[0042] In the usage process, this heat-resistant steel skeleton polyethylene plastic composite pipe can be widely applied to various occasions that need to work in a high-temperature environment, such as the petroleum, chemical, and electric power industries. During the installation process, the appropriate pipeline length and connection method can be selected according to specific requirements to ensure the normal operation of the pipeline. At the same time, during the long-term use process, the performance of the pipeline can be maintained and its service life can be extended through regular inspections and maintenance.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
