Abstract
The invention provides a prefabricated PIR copious cooling heat preservation pipe. The prefabricated PIR copious cooling heat preservation pipe is characterized by comprising an inner pipe, an outer protection pipe, a PIR layer and an isolation layer, wherein the inner pipe is sleeved with the outer protection pipe, the PIR layer is located between the inner pipe and the outer protection pipe and formed in a pouring mode, and the isolation layer is located between the inner pipe and the PIR layer and used for preventing the PIR layer from deforming. The prefabricated PIR copious cooling heat preservation pipe is provided with the outer protection pipe, the inner pipe and the PIR layer located between the outer protection pipe and the inner pipe, and therefore a better heat preservation effect is achieved; a dampproof coating layer is arranged for preventing damp; furthermore, the isolation layer is arranged, and therefore the PIR layer is effectively prevented from deforming. According to the prefabricated PIR copious cooling heat preservation pipe, it is not needed to manually install the outer protection pipe on site, and therefore trouble and labor are better saved.
Description
Technical field
The present invention relates to thermal insulation pipe technical field, particularly relate to the heat preservation pipe prefabricated and manufacture method of a kind of PIR deep cooling.
Background technique
When carrying out Cemented filling to special liquids such as liquid nitrogen, need to carry out Insulation to conveyance conduit, generally on the pipeline welded, manually do prefabricated shell splicing insulation now, and then pillar carries out operation outside making vapor barrier, but need the expenditure of labour cost like this, install simultaneously and also need the regular hour, affect the production schedule; That a section piece of block shell and outer pillar are installed during owing to installing, so the place connected with two sections of outer pillars between two pieces of prefabricated thermal insulation shells all can affect overall heat insulation effect.
Summary of the invention
The features and advantages of the present invention are partly stated in the following description, or can be apparent from this description, or learn by putting into practice the present invention.
For overcoming the problem of prior art, the invention provides a kind of PIR deep cooling heat preservation pipe prefabricated, it is characterized in that, comprising: interior pipe; Outer pillar, is enclosed within outside this interior pipe; Poly-isocyanuric acid lipid layer, between this interior pipe and this outer pillar, this poly-isocyanuric acid lipid layer is formed by the mode of cast; Separation layer, between this interior pipe and this poly-isocyanuric acid lipid layer, for preventing this poly-isocyanuric acid lipid layer generation deformation.
Preferably, moisture-proof coating layer is also scribbled at the madial wall of this outer pillar.
Preferably, this moisture-proof coating layer is fire-retardant matizhi.
Preferably, this separation layer is polyethylene.
Preferably, this separation layer is release agent coating.
Preferably, this release agent coating is coated in the outer surface of this interior pipe.
Preferably, this outer pillar adopts iron sheet, aluminium skin, stainless steel or color steel.
Preferably, the length of this outer pillar is not less than 3m.
Preferably, the length of this outer pillar is 6m.
By reading specification, those of ordinary skill in the art will understand the characteristic sum content of these technological schemes better.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the present invention particularly in conjunction with example, advantage of the present invention and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation of the present invention, and does not form restriction of going up in all senses of the present invention, in the accompanying drawings:
Fig. 1 is the heat preservation pipe prefabricated structural representation of the PIR deep cooling of the embodiment of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of PIR deep cooling heat preservation pipe prefabricated, it is characterized in that, comprising: interior pipe 3; Outer pillar 1, is enclosed within outside interior pipe 3; Poly-isocyanuric acid fat (PolyisocyanurateFoam, PIR) layer 4, between interior pipe 3 and outer pillar 4, this poly-isocyanuric acid lipid layer 4 is formed by the mode of cast; Separation layer 6, between this interior pipe and this poly-isocyanuric acid lipid layer, for preventing this poly-isocyanuric acid lipid layer generation deformation.Because thermal insulation pipe is generally for carrying hotter material such as steam, or the liquid nitrogen etc. that temperature is lower, and poly-isocyanuric acid lipid layer 4 is by cold and hot impact, expand with heat and contract with cold thus cause deformation, the present invention is in order to prevent the generation of this phenomenon, introduce separation layer 6, this separation layer 6 can be polyethylene, also can be release agent coating.According to releasing agent layer, then this release agent coating needs the outer surface being coated in this interior pipe 3, and that is, release agent coating is formed by outer surface releasing agent being sprayed on interior pipe 3.
In the specific implementation, this outer pillar 4 can adopt iron sheet, aluminium skin, stainless steel or color steel, and the length of this outer pillar 4 is not less than 3m.In the present embodiment, the length of outer pillar is 6m.Like this without the need to being docked by multistage thermal insulation pipe, make better heat preservation.
In addition, also scribble moisture-proof coating layer 5 at the madial wall of this outer pillar 1, this moisture-proof coating layer is fire-retardant matizhi, so can be effectively moistureproof, prevents condensed water from permeating.
PIR deep cooling provided by the invention is heat preservation pipe prefabricated has outer pillar, interior pipe and the poly-isocyanuric acid lipid layer between outer pillar and interior pipe, there is better heat insulation effect, be more provided with moisture-proof coating layer, for protection against the tide, also be provided with separation layer, effectively prevent poly-isocyanuric acid lipid layer generation deformation.This PIR deep cooling is heat preservation pipe prefabricated installs outer pillar without the need to manual site, more save trouble and labor.
Above with reference to the accompanying drawings of the preferred embodiments of the present invention, those skilled in the art do not depart from the scope and spirit of the present invention, and multiple flexible program can be had to realize the present invention.For example, to illustrate as the part of an embodiment or the feature that describes can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the present invention, not thereby limit to interest field of the present invention that the equivalence change that all utilizations specification of the present invention and accompanying drawing content are done all is contained within interest field of the present invention.
