[0024] Specifically, the insulation pipe 2 includes a phase change material energy storage layer 101, an insulation layer 102, and a protective shell 103 for covering the phase change material energy storage layer 101 and the insulation layer 102, and the phase change material energy storage layer 101 encloses an installation cavity 104 for inserting the stainless steel pipe 1.
[0025] The stainless steel pipe 1 is insulated by wrapping an insulation pipe 2 around the outer periphery of the stainless steel pipe 1, wherein the insulation bag includes a phase change material energy storage layer 101, an insulation layer 102, and a protective shell 103 for wrapping the phase change material energy storage layer 101 and the insulation layer 102, and the phase change material energy storage layer 101 encloses an installation cavity 104 for inserting the stainless steel pipe 1, the phase change material energy storage layer 101 has good thermal stability, and cooperates with the external insulation layer 102 for insulation, and then further insulated by the protective shell 103, so that the entire stainless steel pipe 1 system has a good insulation effect, can store heat, and has the advantages of high temperature resistance, fire retardancy, and long service life.
[0026] like Figure 1 As shown, the phase change material energy storage layer 101 in this embodiment is further explained, wherein the phase change material energy storage layer 101 adopts solid paraffin, which is difficult to encapsulate and thus difficult to directly apply to the pipeline compared to the traditional phase change material generally using liquid phase change material. In addition, the process of the phase change material in the present application is melt copolymerization, so that the entire phase change material energy storage layer 101 is in a solid state, which is more convenient for the production of the protection tube, and the solid paraffin has good thermal stability, and the phase change temperature and phase change latent heat are relatively favorable, which has a good thermal insulation effect on the stainless steel tube 1.
[0027] In addition, the phase change material energy storage layer 101 directly contacts the stainless steel tube 1 , and utilizes the thermal stability of fixed paraffin to improve the high temperature resistance, and realizes the heat preservation function through the heat preservation layer 102 outside the phase change material energy storage layer 101 .

The PE material has excellent acid and alkali resistance and corrosion resistance, and can effectively resist the erosion of various chemical substances. In addition, the PE sheet is not easy to absorb water, has good thermal insulation and heat insulation properties, can effectively prevent the growth of moisture and mold, and insulate the stainless steel pipe 1.

When the stainless steel tube 1 is wrapped by the insulation tube 2, the annular protrusion 201 is inserted into the fixing groove 202, thereby further improving the stability of the insulation tube 2 wrapping the stainless steel tube 1.

The clamping buckle 304 is provided with a clamping protrusion 305, and the clamping protrusion 305 is inserted into the clamping groove 306 to enclose the insulation pipe 2. The clamping protrusion 305 on the clamping buckle 304 cooperates with the clamping groove 306 to achieve rapid enclosure of the insulation pipe 2, thereby improving the stability and convenience of installation of the insulation pipe 2.
[0034] Furthermore, a plurality of positioning protrusions 307 are formed on the protective shell 103, and a positioning groove 308 for the positioning protrusions 307 to be inserted into is formed on the protective shell 103. During the installation process of the insulation pipe 2, the positioning protrusions 307 will be inserted into the positioning grooves 308, thereby further improving the installation stability of the insulation pipe 2.
[0035] Preferably, the snap-fit structures 301 are respectively arranged at both ends of the protective shell 103 and are staggered, and the end snap-fit portions 302 are staggered along the arrangement direction, that is, the snap-fit buckles 304 and the snap-fit grooves 306 are staggered, thereby further improving the reliability of the buckling of the insulation shell.
