[0024] Furthermore, the present utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the protection scope of the present utility model herein.

An inner steel 103 is arranged in the inner cavity of the middle steel 102. The outer steel 101, the middle steel 102, and the inner steel 103 cooperate, which can significantly improve the comprehensive protection efficiency of the steel pipe, enhance its ability to resist multiple impacts and external pressures, and provide a more comprehensive and solid protection barrier for the steel pipe;

[0027] The structure strengthening unit 200 includes a transition layer 201 fixedly installed between the outer steel 101 and the middle steel 102. A number of groups of reinforcing ribs 202 evenly distributed are arranged in the inner cavity of the transition layer 201. A ceramic layer 203 is fixedly installed between the middle steel 102 and the inner steel 103. A buffer layer 204 is arranged on the outer surface of the ceramic layer 203, and a heat insulation layer 205 is arranged inside the ceramic layer 203. A nano-sheet layer 206 is adhesively connected to the inner side of the ceramic layer 203. On the basis of the three-layer steel pipe structure, the transition layer 201 and the ceramic layer 203 are introduced as additional protection barriers. The transition layer 201 not only is located between the three-layer steel pipes, plays an effective buffering role, reduces the direct damage of the impact force to the steel pipe, but also the several groups of reinforcing ribs 202 configured inside significantly enhance the overall hardness and structural stability of the steel pipe. In addition, the setting of the buffer layer 204 further disperses and absorbs the impact force when the steel pipe encounters external force impacts, protecting the steel pipe from damage. At the same time, the introduction of the heat insulation layer 205 provides the steel pipe with the ability to resist external high temperatures, ensuring that the steel pipe can still maintain stable performance in extreme heat environments. The application of the nano-sheet layer 206 greatly enhances the corrosion resistance of the steel pipe, extending the service life and safety of the steel pipe.

A multi-layer structure design, such as a gradient coating or a composite coating, can be adopted to further improve the wear resistance and impact resistance of the coating.

[0029] The inner layer of the inner steel 103 is provided with a polymer ceramic composite coating 105, and the polymer ceramic composite coating 105 is made of polyimide and alumina, which strengthens the hardness of the inner steel 103 and also strengthens its heat resistance.

[0030] The reinforcing ribs 202 are made of continuous fibers and have the characteristics of high strength, high stiffness, and anti-fatigue.

[0031] The ceramic layer 203 is made of an alumina-based composite material and has higher hardness and better impact resistance.

[0032] The buffer layer 204 is made of high-elastic polyurethane foam, which improves the buffering of the force when the steel pipe is subjected to external force impacts.

[0033] During use, the outer steel 101, middle steel 102, and inner steel 103 cooperate to significantly improve the comprehensive protection efficiency of the steel pipe, enhance its ability to resist multiple impacts and external pressures, and provide a more comprehensive and solid protection barrier for the steel pipe. On the basis of the three-layer steel pipe structure, the transition layer 201 and ceramic layer 203 are introduced as additional protection barriers. The transition layer 201 not only lies between the three-layer steel pipes, playing an effective buffering role and reducing the direct damage of the impact force to the steel pipe, but also the several groups of reinforcing ribs 202 configured inside significantly enhance the overall hardness and structural stability of the steel pipe. In addition, the setting of the buffer layer 204 further disperses and absorbs the impact force when the steel pipe encounters external force impacts, protecting the steel pipe from damage. At the same time, the introduction of the heat insulation layer 205 endows the steel pipe with the ability to resist external high temperatures, ensuring that the steel pipe can still maintain stable performance in extreme heat environments. The application of the nanosheet layer 206 greatly enhances the corrosion resistance of the steel pipe, extending the service life and safety of the steel pipe. The nano wear-resistant alloy coating 104 made of carbide improves the wear resistance and corrosion resistance of the steel pipe surface. The polymer ceramic composite coating 105 made of polyimide and alumina strengthens the hardness of the inner steel 103 and its heat resistance at the same time.
