Abstract
The utility model discloses a foamed ceramic thermal insulation tube. The foamed ceramic thermal insulation tube comprises a metal tube, the inner wall of the metal tube is provided with a foamed ceramic layer, namely an inner layer, the outer wall of the metal tube is also provided with a foamed ceramic layer, namely an outer layer, the surfaces of the foamed ceramic layers are like general exterior wall tiles, and the foamed ceramic layers have a low bibulous rate, can bear various winds and rain, and are free from pollution. The foamed ceramic thermal insulation tube has high thermal insulation efficiency and a long service life, resource waste is significantly reduced, and the foamed ceramic thermal insulation tube is suitable for transportation of liquid and gas which need thermal insulation in the chemical industry, the petrochemical industry and the steam transportation industry.
Description
Technical field
The utility model relates to pipe insulation heat-insulating technique field, specifically belongs to a kind of foamed ceramic thermal insulation pipe that is used for pipe insulation.
Background technique
Existing pipe insulation is protected with asbestos usually and is wrapped up in metallic conduit, and what have also wraps up the aluminium skin again outside asbestos, proved that at present asbestos have public hazards, and asbestos can be carcinogenic; And the aluminium skin is prone to oxidation, and under rainy or wet environment, the asbestos suction causes protected metallic conduit oxidation, transportation of substances to leak, and causes waste or forms public hazards, and this type of pipeline usually needs periodic maintenance, replacing, causes the social resources wave to give up.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing technology, the purpose of the utility model provides a kind of foamed ceramic thermal insulation pipe.
The foamed ceramic thermal insulation pipe of the utility model comprises metal tube, and its technological scheme is: it is internal layer that the inwall of said metal tube is provided with the foamed ceramic layer, and the metal tube outer wall also is provided with the foamed ceramic layer for outer.
The thickness of said internal layer foamed ceramic layer is 1～3mm.
The thickness of said outer foamed ceramic layer is 10～50mm.
The beneficial effect of the utility model is: the surface of its foamed ceramic is like general exterior wall ceramic tile, and foaming forms the closed pore insulation, and directly parcel pipeline water absorption rate is low, is not afraid of wind and weather, and is nuisanceless, more can enter a protection surface at the surface glazing material of foamed ceramic; The internal layer of its foamed ceramic makes inner-walls of duct seamless, and the insulating efficiency of the utility model foamed ceramic thermal insulation pipe is high, long service life, and it is useless significantly to have reduced the resource wave.
Below in conjunction with accompanying drawing and body mode of execution thereof the utility model is done further explain.
Description of drawings
Fig. 1 is the structural representation of model utility foamed ceramic thermal insulation pipe.
Mark among the figure: 1-internal layer, 2-metal tube, 3-skin.
Embodiment
As shown in Figure 1, the utility model foamed ceramic thermal insulation pipe is provided with thinness on the inwall of metal tube 2 be that the foamed ceramic layer of 1～3mm is an internal layer 1, and it is that the foamed ceramic layer of 10～50mm is outer 3 that the metal tube outer wall also is provided with thickness.
The optimum thickness of said internal layer 1 foamed ceramic layer is 1mm.
The optimum thickness of said outer 3 foamed ceramic layers is 20mm.
The thickness of said metal tube is 2～5mm, and its optimum thickness is 3 mm.
As the further improvement of the utility model, on the surface of outer 3 foamed ceramic layers, being coated with to carry out has the glaze layer, can further protect this thermal insulation pipe surface.
The insulating efficiency of the utility model foamed ceramic insulating tube is high, and long service life can be used for chemical industry, petrochemical industry and steam and carries the needs insulation gas of industry, the conveying of liquid.
