Abstract
The utility model provides a high-temperature-resistance heat insulation pipe, which comprises a pipe body, heat insulation layers and a protection layer, wherein the heat insulation layers and the protection layer are arranged outside the pipe body from inside to outside, a high-temperature-resistance layer is arranged between the pipe body and the heat insulation layers, the heat insulation layers comprise an inner heat insulation layer and an outer heat insulation layer, a metal reflecting film is arranged between the inner heat insulation layer and the outer heat insulation layer, the inner heat insulation layer is positioned between the high-temperature-resistance layer and the metal reflecting film, the protection layer is a sheath metal pipe plated with zinc on the surface, and formed reinforcing ribs are arranged on the surface of the sheath metal pipe. The high-temperature-resistance heat insulation pipe has the beneficial effects that the multilayer heat insulation structure is adopted, so the temperature resistance and the heat conducting factor of each layer are gradually reduced, the heat loss is small, and the heat insulation performance is good; the metal reflecting film is adopted, so the heat loss in a convection and radiation mode is avoided, the heat loss is reduced, and the heat insulation performance is improved; the zinc plating protection layer is adopted, so corrosive substances are difficult to permeate, the anti-corrosion capability is high, the high-temperature-resistance heat insulation pipe can be directly buried underground, through the formed reinforcing ribs arranged on the surface, the protection layer can reach the sufficient intensity at the thinner thickness, and the pressure resistance capability and the tensile resistance capability are high.
Description
Technical field
The utility model belongs to building material field, especially relates to a kind of high-temperature-resistant thermal-insulation pipe.
Background technique
Thermal insulation pipe exists extensive use in daily life, and city thermal pipeline, original conveyance conduit and central air-conditioner etc. all will be used thermal insulation pipe.In existing technology, resistant to elevated temperatures coating layer is cemented in steel tube surface, can not alleviate the impact of carrying flowing medium vibrations to produce, and coating layer easily comes off, and makes thermal insulation pipe resistance to high temperature variation; The thermal expansion coefficient of coating layer and steel pipe is inconsistent, and when temperature variation is violent, both deformation extents are inconsistent, and both are consolidated, and cause breaking of coating layer, shortens the working life of thermal insulation pipe; Thermal insulation layer is few, and structure is single, can not avoid heat to scatter and disappear with convection current, radiation mode, and heat loss is large, and properties of heat preservation and energy saving is poor; In addition, protective coating is too thin, outer insufficient strength, and easily because pressurized is out of shape, and blocked up, will increase substantially the cost of production of product again.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, good heat insulating, antiseptic power is strong, cost is low and resistance to compression resistance to tension is strong high-temperature-resistant thermal-insulation pipe.
The technical solution of the utility model is: a kind of high-temperature-resistant thermal-insulation pipe, comprise outer thermal insulation layer and the protective coating from inside to outside of body and body, between described body and thermal insulation layer, be provided with high-temperature-resistant layer, described thermal insulation layer comprises inner thermal insulating layer and external thermal insulation, between described inner thermal insulating layer and external thermal insulation, be provided with metallic reflective coating, described inner thermal insulating layer between high-temperature-resistant layer and metallic reflective coating, the overcoat metal tube that described protective coating is plating zinc on surface, there is the stiffening rib of moulding on its surface.
Further, described high-temperature-resistant layer is stupalith.
Further, described inner thermal insulating layer is microporous calcium silicate thermal insulation layer or magnesium metasilicate heat preservation layer.
Further, described external thermal insulation is polyurethane foam plastics thermal insulation layer.
Further, described metallic reflective coating is aluminium foil.
Further, described stiffening rib in the shape of a spiral.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, multi-layer heat preserving structure is set, temperature tolerance and the thermal conductivity of each layer reduce gradually, and thermal loss is little, good heat insulating; Metallic reflective coating is set, has avoided heat to scatter and disappear in the mode of convection current, radiation, reduce heat loss, improve thermal insulation property, good energy-conserving effect; Be provided with zinc-plated protective coating, make corrosive goods blame infiltration, antiseptic power is strong, can direct-burried in underground, the stiffening rib of its surface forming, makes protective coating reach enough intensity with thinner thickness, resistance to compression resistance to tension is strong.
