Description
Technical field
It the utility model is related to gas pipeline, and in particular to a kind of wear-resisting, scratch resistant buried PE gas pipelines.
Background technology
At present, due to a large amount of utilization of natural gas, Plastic Gas pipeline is widely used to municipal administration, rural area Gas Pipe
During net is built.The material of Plastic Gas pipeline is mostly polyethylene（Abbreviation PE gas pipelines）, its strength of materials can fully meet
The fuel gas transmission of mesolow.Although PE gas pipelines have many advantages, such as, it need to fill gas pipeline in work progress
In underground, due to construction environment is poor or material transport during operation it is improper, be very easy to that material appearance is caused to damage
Wound, directly affects the service life of material, and serious even causes security incident.Therefore, it is necessary to produce a kind of with wear-resisting, super
The PE gas pipelines of scratch resistance function.
The content of the invention
The purpose of this utility model is for overcome the deficiencies in the prior art, there is provided a kind of wear-resisting, scratch resistant buried use
PE gas pipelines, the PE gas pipeline costs are low, and in the case where neither influenceing the installation situation of existing pipeline, and can enough reduces fires to PE
The damage of feed channel, extend the service life of PE gas pipelines.
What the purpose of this utility model can be realized by following technical scheme：
A kind of wear-resisting, scratch resistant buried PE gas pipelines, including PE Gas Pipes, it is characterised in that：The PE combustion gas
The external peripheral surface of tube wall covers one layer of wear-resisting, scratch resistant material layer through co-extrusion, forms composite bed structural pipe wall, described compound
Layer structural pipe wall internal layer be PE gas pipelines agent structure layer, outer layer be PE gas pipelines protective layer, the PE combustion gas
The agent structure layer of pipeline is different from the material of protective layer, and the agent structure thickness degree of the PE gas pipelines is more than protective layer
Thickness, the thickness of the protective layer is 0.5 ~ 1.0mm.
The thickness of the protective layer is 1mm.
The protective layer uses ultra-high molecular weight polyethylene.
The protective layer uses nylon material.
The agent structure layer of PE gas pipelines uses high density polyethylene (HDPE).
The beneficial effects of the utility model：The utility model in the external peripheral surface of PE combustion gas tube walls through co-extrusion by covering
One layer of wear-resisting, scratch resistant protective layer, forms composite bed structural pipe wall, and the internal layer of the composite bed is the body junction of PE gas pipelines
Structure layer, outer layer are the protective layer of PE gas pipelines.Because the agent structure layer of PE gas pipelines is according to existing product structure
Technical standard is realized, therefore does not interfere with its mechanical property and service life.In PE combustion gas tube wall outer cladding layer protective layers, warp
The PE gas pipelines crossed after cladding, because protective layer is made of that have wear-resisting, scratch resistant material, are provided with PE gas pipelines
Super scratch resistance capability, therefore no matter PE gas pipelines are draggings in transport process or in installation process, to PE combustion gas
The destruction of pipe main body bearing structure will greatly reduce.Due to the outer layer protection layer material and internal layer body junction of composite bed tube wall
The material of structure layer is different, and its bond strength will not be too strong, and the thickness of protective layer be 0.5 ~ 1.0mm, is being heated or electric
During fusion welding, it is easy to peel off the protective layer at linkage section, so as to not interfere with the installation of pipeline.The utility model PE Gas Pipes
Road also remains all advantages of original PE gas pipelines while adhesion strength is increased.Extend PE gas pipelines
Service life, avoid the generation of security incident.
The thickness of the protective layer is 1mm.The thickness can either be effectively protected the agent structure of PE gas pipelines, and just
In stripping.
The protective layer uses ultra-high molecular weight polyethylene.This material has superpower wearability, self lubricity, intensity
It is strong to compare high, chemical property stabilization, ageing resistace.
The protective layer uses nylon material, and nylon has very high mechanical strength, and softening point is high, heat-resisting, coefficient of friction
It is low, it is wear-resistant.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view of the present utility model；
Fig. 3 is Pipe installing connection diagram of the present utility model.
In accompanying drawing, 1 is protective layer, and 2 be main body structure sheaf, and 3 be heat-melting butt-joint mouth.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Referring to shown in Fig. 1 to Fig. 2, it is a kind of it is wear-resisting, scratch resistant it is buried use PE gas pipelines, including PE Gas Pipes, it is described
The external peripheral surface of PE combustion gas tube walls covers one layer of wear-resisting, scratch resistant material layer through co-extrusion, forms composite bed structural pipe wall, institute
The internal layer for stating composite bed structural pipe wall is the agent structure layer 2 of PE gas pipelines, and outer layer is the protective layer 1 of PE gas pipelines, should
Protective layer 1 is protected to the agent structure layer 2 of whole PE gas pipeline, and the protective layer 1 can protect the master of PE gas pipelines
Body structure sheaf 2 avoids scratch in carrying or installation process.The agent structure layer 2 of the PE gas pipelines and the material of protective layer 1
Material is different, and the agent structure layers 2 of the PE gas pipelines uses high density polyethylene (HDPE), and the performance of PE gas pipelines is best.It is described
Protective layer 1 uses ultra-high molecular weight polyethylene.Or the protective layer 1 uses nylon material.The main body of the PE gas pipelines
The thickness of structure sheaf 2 is more than the thickness of protective layer 1, and the thickness of agent structure layer 2 of PE gas pipelines meets relevant national standard rule
It is fixed.The thickness of the protective layer 1 is 0.5~1.0mm.The thickness of the protective layer 1 is 1mm, is most preferred embodiment.PE Gas Pipes
The agent structure layer 2 in road and the protective layer 1 of PE gas pipelines are integrally formed using co-extrusion machine, make the agent structure of PE gas pipelines
Layer 2 is in close contact with protective layer 1, but because agent structure layer 2 is different from the material of protective layer 1, therefore its bond strength is not
Can be too strong, the protective layer can protect agent structure layer, be easy to separate with agent structure layer again, facilitate two sections of PE gas pipeline phases
Even.The length of this PE gas pipelines is according to customer requirement customized production.
Shown in Figure 3, the utility model is wear-resisting, scratch resistant buried when being installed with PE gas pipelines, only need by it is wear-resisting,
It is scratch resistant it is buried need the protective layer 1 of coupling part to peel off with PE gas pipelines, expose agent structure layer 2, pass through two sections of PE
The heat-melting butt-joint mouth 3 of gas pipeline docks, you can realizes wear-resisting, scratch resistant buried with PE gas pipeline agent structures layer 2
Heat-melting butt-joint or electric smelting connection, the utility model are very convenient when installing.
Embodiment above is only that the utility model preferred embodiment is described, not to of the present utility model
Scope is defined, and on the premise of not departing from and the utility model is related to spirit, one of ordinary skill in the art is to this practicality
The various modifications and improvement that new technical scheme is made are each fallen within the protection domain that claim of the present utility model determines.
