Abstract
The utility model discloses a kind of natural gas tubes convenient for heat-melting butt-joint, including natural gas tube ontology, the natural gas tube ontology have in being followed successively by internal layer, explosion-proof layer, flame-retardant layer, damp-proof layer and protective layer outside, and hot melt adhesive is filled between adjacent two layers, the utility model is it is expected that solve the problems, such as that existing natural gas tube is difficult to carry out heat-melting butt-joint.
Description
Technical field
The utility model relates to new material technology fields, and in particular to a kind of natural gas tube convenient for heat-melting butt-joint.
Background technique
Natural gas line, which refers to, is transported to urban gas center or industrial enterprise's use from exploitation ground or treatment plant for natural gas
The pipeline at family, also known as gas pipeline, Natural Gas Pipeline Transportation is low with transportation cost, take up an area less, construction is fast, oil gas freight volume
Greatly, security performance is high, transport loss is few, is unique side of a large amount of conveying natural gases at present using natural gas line conveying natural gas
Formula, in world's pipeline overall length, natural gas line accounts for about half.Existing natural gas tube most steel pipe and external insulation layer again, by
In steel pipe fusing point it is higher make natural gas tube be difficult to using hot melt by the way of docked, be typically only capable to using welded connecting.
Utility model content
The purpose of this utility model is to provide a kind of natural gas tubes convenient for heat-melting butt-joint, are solved with expectation existing natural
Tracheae is difficult to the problem of carrying out heat-melting butt-joint.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of natural gas tube convenient for heat-melting butt-joint, including natural gas tube ontology, the natural gas tube ontology have interior to outer
It is followed successively by internal layer, explosion-proof layer, flame-retardant layer, damp-proof layer and protective layer, and is filled with hot melt adhesive between adjacent two layers.
The material of the internal layer is the mixture of polyethylene, stabilizer, antioxidant and carbon black, and the quality of carbon black accounts for internal layer
The 2.0%~2.5% of gross mass.
The explosion-proof layer is the reticular structure of nylon braiding, and rubber is filled on nylon.
The material of the flame-retardant layer is neoprene.
The material of the damp-proof layer is polyester fiber.
The material of the protective layer is polyethylene, and the outer layer of the damp-proof layer is coated with chlorinated rubber anticorrosive paint layer, institute
Chlorinated rubber anticorrosive paint is stated to be placed between hot melt adhesive and protective layer.
Compared with prior art, the utility model has the beneficial effects that：
The utility model causes cost high instead of the effective steel pipe of previous combustion gas as back boxing, is not easy heat-melting butt-joint,
Metallic netted structural is equipped in the utility model, metal mesh can bear the excessive bring tension of gas pressure, prevent pipeline quick-fried
Fried, the utility model is additionally provided with flame-retardant layer and damp-proof layer, to protect the combustion gas in internal layer not burned and make moist, since this is practical
Novel major part material is all nonmetallic so that natural gas tube is convenient for heat-melting butt-joint.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of the utility model one embodiment.
In figure, 1- internal layer, 2- explosion-proof layer, 3- flame-retardant layer, 4- damp-proof layer, 5- protective layer.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment 1：
A kind of natural gas tube convenient for heat-melting butt-joint, including natural gas tube ontology, the natural gas tube ontology have interior to outer
It is followed successively by internal layer 1, explosion-proof layer 2, flame-retardant layer 3, damp-proof layer 4 and protective layer 5, and is filled with hot melt adhesive between adjacent two layers, is made
Natural gas tube has the characteristics of explosion-proof, fire-retardant, moisture-proof, anti-corrosion.
Embodiment 2：
In order to make natural gas line intensity with higher and acid-alkali-resistant degree, on the basis of embodiment 1, the internal layer 1
Material be polyethylene, stabilizer, antioxidant and carbon black mixture, and the quality of carbon black account for internal layer gross mass 2.0%~
2.5%, polyethylene is easy photooxidation, thermal oxide, ozone decomposition, and degradation is easy to happen under action of ultraviolet radiation, and carbon black is to poly- second
Alkene has excellent light shield effect, while stabilizer, antioxidant can reach uvioresistant and oxidation resistant effect.
Embodiment 3：
In order to make to explode in fuel gas conduit because air pressure is excessive, on the basis of embodiment 1, the explosion-proof layer 2 is nylon volume
The reticular structure knitted, and rubber is filled on nylon, and rubber is filled on nylon, nylon has excellent mechanical strength,
In order to bear the excessive brought tension of air pressure.
Embodiment 4：
In order to which the natural gas in protective conduit is to avoid being ignited, on the basis of embodiment 1, the material of the flame-retardant layer 3
Matter is neoprene, and neoprene has certain anti-flammability.
Embodiment 5：
In order to which the natural gas in protective conduit does not make moist, on the basis of embodiment 1, the material of the damp-proof layer 4 is poly-
Ester fiber.
Embodiment 6：
Natural gas line is usually embedded in ground end, and extexine corrodes in order to prevent, and the material of the protective layer 5 is polyethylene,
And the outer layer of the damp-proof layer 4 is coated with chlorinated rubber anticorrosive paint layer, the chlorinated rubber anticorrosive paint is placed on hot melt adhesive and prevents
Between sheath 5, chlorinated rubber anticorrosive paint adhesive force is not easily to fall off by force, and equally has the spy of acid-alkali-corrosive-resisting with polyethylene material
Property.
Although reference be made herein to the utility model is described in multiple explanatory embodiments of the utility model, still,
It should be understood that those skilled in the art can be designed that a lot of other modification and implementations, these modifications and implementations
