China at this stage, various energy crises and environmental problem emerge one after another, and how to realize that energy conservation and environmental protection is the transitional period
Chinese urgent problem to be solved, in people's lives and industrial processes, people using a large amount of hot water, steam and other
The heating agent of form, and the environment temperature that these heat medium temperatures are projecting, so during transportation, having part heating power and scattering and disappearing
Into environment, unnecessary waste but also meeting generation environment problem are caused.Thoroughly prevent heating agent and transmit to function of environment heat emission be
It is impossible, but the radiation loss city for reducing heating agent conveyance conduit is very necessary and required.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of two-tube small-bore insulating tube, can solve people
Using the heating agent of a large amount of hot water, steam and other forms, and the environment temperature that these heat medium temperatures are projecting, so transporting
It during defeated, have part heating power and is lost in environment, cause unnecessary waste but also meeting generation environment problem.
In order to solve the above technical problems, the utility model provides the following technical solutions:
The utility model provides a kind of two-tube small-bore insulating tube, including heat preservation tube body, the heat preservation tube body include
Outer protection tube, instrumentation tubes and insulating layer, there are two the instrumentation tubes are set, two instrumentation tubes are set in outer protection tube, two work
Make to be equipped with insulating layer between pipe and outer protection tube, the insulating layer is polyurethane insulation coating, and the polyurethane insulation coating is more by polyethers
The pure and mild two kinds of chemical raw materials of isocyanates of member foam.
As a kind of optimal technical scheme of the utility model, the outer protection tube is round steel pipe, the outer protection tube outside
Equipped with erosion resistant coating.
As a kind of optimal technical scheme of the utility model, the instrumentation tubes are seamless steel pipe or welded still pipe.
As a kind of optimal technical scheme of the utility model, the inner wall of the instrumentation tubes is equipped with thermostable rustproof paint layer.
As a kind of optimal technical scheme of the utility model, the size structure of two instrumentation tubes is consistent.
Compared with prior art, the attainable beneficial effect of the utility model is:
In the case where fixed caliber and insulating layer dosage, the optimization of layout of beam line is set the utility model between two instrumentation tubes
It sets；Realize that the shared insulating layer performance indicator of two-tube small-bore pipe is consistent always, even density；Two-tube small-bore insulating tube is being constructed
When, the width of trench becomes smaller, to effectively reduce earthwork digging amount；In construction transportational process, two root canal roads synthesize one
Pipeline shortens the construction period；Energy saving, thermal insulation material dosage is small, reduces cost, improves production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein: 1, keeping the temperature tube body；2, outer protection tube；3, instrumentation tubes；4, insulating layer.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
It please refers to shown in Fig. 1, the utility model provides a kind of two-tube small-bore insulating tube, including heat preservation tube body 1, heat preservation
Tube body 1 includes outer protection tube 2, instrumentation tubes 3 and insulating layer 4, and there are two instrumentation tubes 3 are set, two instrumentation tubes 3 are set in outer protection tube 2,
Insulating layer 4 is equipped between two instrumentation tubes 3 and outer protection tube 2, insulating layer 4 is polyurethane insulation coating, and polyurethane insulation coating is more by polyethers
The pure and mild two kinds of chemical raw materials of isocyanates of member foam.
Outer protection tube 2 is round steel pipe, is equipped with erosion resistant coating on the outside of outer protection tube 2.Instrumentation tubes 3 are seamless steel pipe or welded still pipe.
The inner wall of instrumentation tubes 3 is equipped with thermostable rustproof paint layer.The size structure of two instrumentation tubes 3 is consistent.
Concrete operating principle: being coated with thermostable rustproof paint layer in 3 inner wall of instrumentation tubes, prevent instrumentation tubes 3 for a long time high temperature,
Work inside pipe wall corrosion under wet environment, influences the service life of insulating tube, and be coated with erosion resistant coating on the outside of outer protection tube 2,
It prevents outer protection tube 2 from contacting for a long time with soil, corrodes outer protection tube, be equipped in the outside of instrumentation tubes 3 by the pure and mild isocyanic acid of polyether polyols
Polyurethane insulation coating made of ester two kinds of chemical raw materials foaming prevents scattering and disappearing for heat in insulating tube, then its exterior is equipped with
Outer protection tube 2.
The attainable beneficial effect of the utility model is: the utility model is the case where fixing caliber and insulating layer dosage
Under, the optimal setting of layout of beam line between two instrumentation tubes；Realize that the shared insulating layer performance indicator of two-tube small-bore pipe is consistent always, it is close
Degree is uniform；In construction, the width of trench becomes smaller two-tube small-bore insulating tube, to effectively reduce earthwork digging amount；It is applying
During labour movement is defeated, two root canal roads synthesize a root canal road, shorten the construction period；Energy saving, thermal insulation material dosage is small, reduces cost,
Improve production efficiency.
