Abstract
The utility model discloses a kind of buried enhanced impermeable composite petroleum pipeline of thermoplastic in gas station, barrier layer (1) including being arranged on internal layer, the fiber-reinforced layer (2) of the barrier layer (1) outer layer is arranged on, is arranged on the polypropylene resin layer (3) of the fiber-reinforced layer (2) outer layer.The petroleum pipeline conveys suitable for buried petroleum pipeline, due to that there is provided barrier layer, can prevent petroleum media from oil pipe internal penetration to the external world, and reduce oligomer precipitation；Due to that there is provided fiber-reinforced layer, petroleum pipeline can be made to be not limited in bending, can more freely be laid；Due to that there is provided polypropylene resin layer, the bulk strength and impact resistance of petroleum pipeline can be greatly improved, prevent it from damaging in use, extend its service life.
Description
Technical field
It the utility model is related to a kind of buried enhanced impermeable composite petroleum pipeline of thermoplastic in gas station.
Background technology
At present, anti-corrosion pipeline is widely used in the essential industry such as chemical industry, petrochemical industry, metallurgy, nuclear energy and military project production division
Convey corrosive liquid medium.The anti-corrosion pipeline of existing non-metallic liner, the resistance to penetrating power of its tube wall are poor, it is impossible to effectively
Ground prevents the infiltration of fluid and its evaporant, it is difficult to reach higher osmotic-pressure-tolerant international standard requirement, and easily because of fluid
And the permeating volatile of evaporant triggers environmental pollution.And petroleum pipeline is much required for being embedded to underground, therefore can be by very big
Extruding, it is therefore desirable to the impact resistance of pipeline, and intensity there are certain requirements, and traditional petroleum pipeline is overall strong
Spend it is relatively low, it is short without correlated performance, service life.
Utility model content
The purpose of the utility model is to provide that a kind of gas station is buried to use thermoplastic the defects of presence for prior art
Enhanced impermeable composite petroleum pipeline.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of gas station is buried to use thermoplastic
Enhanced impermeable composite petroleum pipeline, including the barrier layer 1 of internal layer is arranged on, it is arranged on the fiber of the outer layer of barrier layer 1
Enhancement layer 2, it is arranged on the polypropylene resin layer 3 of the outer layer of fiber-reinforced layer 2.
Further, the barrier layer 1 is made up of ethylene-vinyl alcohol copolymer or Vingon.
Further, the fiber-reinforced layer 2 is made up of complex polyester monofilament.
Further, the polypropylene resin layer 3 is formed by nano-material modified.
The beneficial effects of the utility model：The petroleum pipeline conveys suitable for buried petroleum pipeline, because there is provided resistance
Interlayer, petroleum media can be prevented from oil pipe internal penetration to the external world, and reduce oligomer precipitation；Because there is provided fiber reinforcement
Layer, petroleum pipeline can be made to be not limited in bending, can more freely be laid；Due to there is provided polypropylene resin layer,
The bulk strength and impact resistance of petroleum pipeline can be greatly improved, prevents it from damaging in use, extends its use
Life-span.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, it is related to a kind of buried enhanced impermeable composite petroleum pipeline of thermoplastic in gas station, including set
The barrier layer 1 in internal layer is put, the fiber-reinforced layer 2 of the outer layer of barrier layer 1 is arranged on, is arranged on outside the fiber-reinforced layer 2
The polypropylene resin layer 3 of layer.The composite petroleum pipeline of said structure, it is conveyed suitable for buried petroleum pipeline, due to setting
Barrier layer 1, can prevent petroleum media from oil pipe internal penetration to the external world, and reduce oligomer precipitation；Because there is provided fibre
Enhancement layer 2 is tieed up, petroleum pipeline can be made to be not limited in bending, can more freely be laid；Because there is provided polypropylene
Resin bed 3, the bulk strength and impact resistance of petroleum pipeline can be greatly improved, prevents it from damaging in use, extended
Its service life.
Further preferred scheme is that the barrier layer 1 is made up of ethylene-vinyl alcohol copolymer or Vingon.
Above-mentioned barrier layer has the characteristic of low permeability, barrier and chemical-resistant resistance, can not only prevent the corrosivity such as petroleum media
Liquid from oil pipe internal penetration to the external world can, and the transit dose of the media such as oxygen, carbon dioxide can also be greatly lowered, and have
Standby two-sided heat-sealing performance.
Further preferred scheme is that the fiber-reinforced layer 2 is made up of complex polyester monofilament.Due to fiber-reinforced layer
2 are made up of complex polyester monofilament so that the surface thermal finalization of fiber-reinforced layer 2 is beneficial to improve the overall strength and stiffness of pipeline；
Complex polyester monofilament is bonded between barrier layer and polypropylene resin layer, ensure that petroleum pipeline can not limited in bending
System, has certain free bend performance, laying when being easy to pipeline buried.
Further preferred scheme is that the polypropylene resin layer 3 is formed by nano-material modified.Due to nano material
In the presence of not only making the crushing resistance, modulus and impact resistance of internal layer tubing, be respectively increased than pure hdpe pipe
65%th, 50% and 80% so that the service life of pipeline extends.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
