Abstract
(B, ) insulating tube with polyurethane and polyethylene bridging material. At present because the difference of materials variances and manufacturing process results in becoming one separately each other between prefabricated thermal -insulated hot oil line's polyurethane plastic polyurethane foam heat -preserving layer and the outer pillar, can not accomplish to intercross mutually and arrange, accomplish to combine closely, from the expend with heat and contract with cold that the temperature variation results in, cause outer pillar and the polyurethane plastic polyurethane foam heat -preserving layer nonconformity of moving each other, along with the thermal change of pipeline, the expend with heat and contract with cold of polyurethane and the expend with heat and contract with cold coefficient of outer pillar are not equal, lead to the fact the reduction of pipe network life -span. The utility model discloses the constitution includes: work pipe (b) (b) 1 (b) (b), work outside of tubes side be provided with polyurethane plastic polyurethane foam heat -preserving layer (b) (b) 2 (b) (b), polyurethane plastic polyurethane foam heat -preserving layer's the outside be provided with polyurethane and polyethylene bridging material layer (b) (b) 3 (b) (b), polyurethane and the polyethylene bridging material layer outside be provided with the outer pillar (b) (b) 4 (b) (b) of polyethylene. The utility model is used for the energy is carried. (B, )
Description
technical field:
the utility model relates to a kind of thermal insulation pipe with polyurethane and polyethylene bridge joint material.
background technique:
current prefabricated heat-insulation and heat-preservation pipeline be configured to three parts, be polyethylene outer protective pipe, urethane plastic foam heat-insulation layer, service pipe respectively, wherein, due to the difference of materials variances and manufacturing process between urethane plastic foam heat-insulation layer and outer pillar, cause becoming to be integrated separately each other, can not accomplish mutually to hand over to arrange, accomplish to combine closely, what cause from temperature variation expands with heat and contract with cold, visible bi-material undergoes phase transition separately, instead of synchronously change, outer pillar and urethane plastic foam heat-insulation layer is caused mutually to move inconsistent, along with the change of pipeline heat, expanding with heat and contract with cold of polyurethane is not equal to the coefficient of thermal expansion and contraction of outer pillar, after wherein working steel tube is subject to the contact of hot water, there is thermal expansion, polyurethane also stretches along with the change of steel pipe, this is not just combined in manufacturing process for the polyurethane stretched and outer pillar, there is gap on the contrary, there is the phenomenon of each autokinesis, Steel Pipe Heat is caused to expand, outer pillar or outer pillar welding repaired mouth position are cracked, the moisture of soil enters into polyurethane insulation coating, thermal insulation layer is due to moisture, heat energy in steel pipe is passed to out, cause heat waste, along with a large amount of appearance of moisture, the infiltration of damaged part gets more and more, heat loss is also just increasing, the pipe network life-span is also shorter and shorter.
model utility content:
the purpose of this utility model is to provide a kind of thermal insulation pipe with polyurethane and polyethylene bridge joint material.
above-mentioned object is realized by following technological scheme:
a kind of thermal insulation pipe with polyurethane and polyethylene bridge joint material, its composition comprises: working pipe, described working pipe arranged outside has urethane plastic foam heat-insulation layer, the arranged outside of described urethane plastic foam heat-insulation layer has polyurethane and polyethylene bridge joint material layer, and described polyurethane and polyethylene bridge joint material layer arranged outside have polyethylene outer protective pipe.
beneficial effect:
1. there is polyurethane and polyethylene bridge joint material layer in the utility model between urethane plastic foam heat-insulation layer and polyethylene outer protective pipe, the difference of the materials variances between urethane plastic foam heat-insulation layer and polyethylene outer protective pipe and manufacturing process is merged, make it to become to be integrated each other, accomplish mutually to hand over to arrange, accomplish to combine closely, what cause from temperature variation expands with heat and contract with cold, bi-material can be seen undergo phase transition no longer separately, but synchronously change, outer pillar is made mutually to move consistent with urethane plastic foam heat-insulation layer, and along with the change of pipeline heat, expanding with heat and contract with cold of polyurethane is equal to substantially with the coefficient of thermal expansion and contraction of outer pillar, ensure the raising in full pipe network life-span.
the utility model still adopts polyethylene outer protective pipe, urethane plastic foam heat-insulation layer, working pipe three-in-one structure, distribution sequence does not change, only between outer protective polyethylene pipeline and urethane plastic foam heat-insulation layer, model utility is provided with the bond of polyethylene and polyurethane bi-material, this bond forms friendship on the surface forming the moment and polyurethane that plastic foam temperature layer protected by polyurethane and arranges, become after urethane cures and be integrated, to melt with bond when polyethylene being made the condition of high temperature of pipeline subsequently and together with being staggered in, one is defined again after solidification, define polyethylene thereupon, bond, the form of the tight one of polyurethane three, the insulation pipe of quaternity is become together with working steel tube.
accompanying drawing illustrates:
accompanying drawing 1 is cross-sectional configuration schematic diagram of the present utility model.
embodiment:
embodiment 1:
a kind of thermal insulation pipe with polyurethane and polyethylene bridge joint material, its composition comprises: working pipe 1, described working pipe arranged outside has urethane plastic foam heat-insulation layer 2, the arranged outside of described urethane plastic foam heat-insulation layer has polyurethane and polyethylene bridge joint material layer 3, and described polyurethane and polyethylene bridge joint material layer arranged outside have polyethylene outer protective pipe 4.
embodiment 2:
the making method with the thermal insulation pipe of polyurethane and polyethylene bridge joint material described in a kind of embodiment of utilization 1, the utility model is between outer protective polyethylene pipeline and urethane plastic foam heat-insulation layer, the polyurethane that the bond being provided with polyethylene and polyurethane bi-material is made and polyethylene bridge joint material layer, this polyurethane and polyethylene bridge joint material layer form friendship on the surface forming the moment and polyurethane that plastic foam temperature layer protected by polyurethane and arrange, become after urethane cures and be integrated, to melt with bond when polyethylene being made the condition of high temperature of pipeline subsequently and together with being staggered in, one is defined again after solidification, define polyethylene thereupon, bond, the form of the tight one of polyurethane three, the insulation pipe of quaternity is become together with working steel tube.
Claims (1)
1. one kind has the thermal insulation pipe of polyurethane and polyethylene bridge joint material, its composition comprises: working pipe, it is characterized in that: described working pipe arranged outside has urethane plastic foam heat-insulation layer, the arranged outside of described urethane plastic foam heat-insulation layer has polyurethane and polyethylene bridge joint material layer, and described polyurethane and polyethylene bridge joint material layer arranged outside have polyethylene outer protective pipe.
