Description
Technical field
The present invention relates to thermal insulation apparatus field, relate in particular to a kind of thermal insulation pipe.
Background technique
In life, usually will use pipeline to carry out the conveying of fluid, cold duct, water conveyance conduit, gas pipe line etc. are all used to carry indispensable requirement in life.But due to geographical environment difference, pipeline usually will bear the pressure from external environment, such as environment such as low temperature, high pressure and corrosion.Especially low temperature environment, if the pipeline for transporting fluid does not have thermal insulation property, will directly affect so state and the conveying efficiency of fluid in pipeline, such as the pipeline of transport of water, in the time that the residing ambient temperature of pipeline is lower, if pipeline does not have the function of insulation, so ducted water can be because temperature compared with low and icing, causes proceeding transport.
For another example, the pipeline transporting crude oil, if the residing ambient temperature of pipeline is lower, the travelling speed of crude oil, by slack-off, directly affects conveying efficiency so.
Therefore, a kind of thermal insulation pipe is needed in market badly, can keep the fluid of self and its inside transport in suitable temperature, affected by extraneous low temperature environment little, keeps internal flow conveying efficiency.
Summary of the invention
The object of the invention is to, propose a kind of thermal insulation pipe, with solve in prior art pipeline be affected by the external environment larger, and the affected problem of pipeline inner fluid conveying efficiency causing.
For reaching this object, the present invention by the following technical solutions:
A kind of thermal insulation pipe, comprises that inside, for passing into the inner tube of fluid, is at least provided with two heating tapes on the outer wall of described inner tube, and the outside of described heating tape is enclosed with nanometer material thermal insulation layer, calcium silicate heat-preserving layer, glass fiber reinforced plastics composite material layer and thermal insulation layer successively;
The outside of described thermal insulation layer is provided with outer tube, and the outside of described outer tube is provided with one deck corrosion-resistant coating.
Preferably, described thermal insulation layer is made up of the one in asbestos, glass wool, vermiculite or silicious marl.
Further, the thickness of described thermal insulation layer is 5mm-10mm.
Preferably, described heating tape is thermal resistor heating tape.
Preferably, the heating-up temperature interval of described thermal resistor heating tape is 20 DEG C-120 DEG C.
Preferably, described nanometer material thermal insulation layer is aerosil felt.
Preferably, described outer tube is made up of polythene material.
Preferably, described corrosion-resistant coating is polyurethane lacquer coating.
Further, described heating tape is connected by wire with external heat source.
Beneficial effect of the present invention is: because the thermal insulation pipe in the present invention has heating tape, can heat production under the effect of outside heating source, its outside is provided with multi-layer heat preserving layer, can effectively preserve the heat that heating tape produces, make the fluid transporting in thermal insulation pipe avoid being subject to the impact of extraneous low temperature and corrosive environment, use the thermal insulation pipe in the present invention to transport, conveying efficiency is higher.
The present invention is provided with corrosion-resistant coating at the outermost surface of thermal insulation pipe, and corrosion-resistant coating can effectively protect thermal insulation pipe not to be subject to the threat of the central various corrosive materials of external environment.
Brief description of the drawings
