Embodiment 1

[0026] Embodiment 1, as attached figure 1 and 2 As shown, the self-compensating high-temperature resistant prefabricated direct-buried thermal insulation pipe includes a core pipe 1, a heat insulating layer 2 and an outer protective casing 3. There is a heat insulating layer 2 outside the core pipe 1, and an outer protective casing 3 outside the heat insulating layer 2. , there is not less than one hard heat insulating support ring 4 between the core tube 1 and the outer protective sleeve 3; as attached figure 1 and 2 As shown, the outer protective sleeve 3 adopts a flat-walled outer protective tube. When in use, due to the special structure of the invention, it has a "self-compensation" function when it expands at high temperature, so the structure will not be damaged, so the invention has a high heat preservation effect.

Embodiment 2

[0027] Embodiment 2, as attached Figures 1 to 4 As shown, the difference between the self-compensating high-temperature resistant prefabricated direct-buried thermal insulation pipe and the embodiment 1 is that the outer protective casing 3 of the embodiment 2 adopts a corrugated outer protective pipe.

Embodiment 3

[0028] Embodiment 3, as attached Figures 3 to 6 As shown, the difference between the self-compensating high-temperature-resistant prefabricated direct-buried thermal insulation pipe and the embodiment 2 is that the outer protection casing 3 of the embodiment 3 adopts a spiral outer protection pipe.

[0029] In the above-mentioned embodiments 1, 2 and 3: according to actual needs, the outer protective sleeve 3 can adopt the insulation pipe made of polyvinyl chloride hard plastic in the prior art or the heat preservation tube made of high-density polyethylene hard plastic. Tube or insulation pipe made of glass fiber reinforced plastic material or insulation pipe made of metal material, heat insulation layer 2 can adopt hard insulation material in the prior art, semi-hard insulation material, soft insulation material, elastic foam insulation material, inorganic One or more of porous thermal insulation materials, organic porous thermal insulation materials, inorganic-organic comp...

Abstract

The invention comprises a core tube, an insulating layer and an outer protecting jacket. There is the insulating layer outside the core and the outer protecting jacket outside the insulating layer. There are more than one hard thermal insulation supporting rings between the core tube and the outer protecting jacket. Because of having the expansion self-compensating effect when used at high temp., the structure of the invention can't be destroyed, so as to make it have a good thermal insulation effect.

Description

1. Technical field: [0001] The invention relates to a heat preservation pipe capable of being buried underground, which is a self-compensating high temperature resistant prefabricated direct buried heat preservation pipe. 2. Background technology: [0002] Existing insulation pipes that can be buried underground generally have insulation pipes with the following structures, namely: insulation pipes with rigid insulation tile structure, insulation pipes with polyurethane rigid foam insulation material structure, and rigid insulation materials combined with polyurethane foam Insulation pipes of the structure and insulation pipes of the steel jacket steel insulation structure are as follows: [0003] 1. Insulation pipe with rigid insulation tile structure. It uses perlite tiles to wrap medium steel pipes, and uses perlite tiles as the main body of heat preservation. Since the perlite tile is a hard thermal insulation material, it can be used for pressure-resistant direct-buri...
