Description
Technical field
The present invention relates to a kind of petroleum pipeline, and in particular to improves the petroleum pipeline of corrosion-resistant thermal insulation.
Background technology
One of oil, the main object of geological prospecting, it is a kind of sticky, dark brown liquid, is referred to as " the blood of industry
Liquid ".There is petroleum storage upper crustal some areas.Main component is the mixture of various alkane, cycloalkane, aromatic hydrocarbon.Oil
Corresponding machining sector must be transported after exploitation, just can more preferably be utilized, the petroleum pipeline of wherein transfer oil is then
Essential equipment.And oil is in oil recovery process, because oil paraffin content is too high, it is big to carry oil concentration, often causes oil transportation
Pipeline oil transportation is difficult, and the flow resistance of the oil especially in cold season, petroleum pipeline can be significantly increased, it is necessary in oil
Discharge pressure is heated or increased on pipeline to solve the problems, such as oil transportation difficulty.And for increasing discharge pressure, this method energy consumption
Greatly.Existing petroleum pipeline in order to be incubated, generally using heat-insulation layer reduce pipe in oil heat scatter and disappear, still, its exist
Some shortcomings, the heavier mass of bitumen layer, the load of pipeline is increased weight, and be air between heat-insulation layer and inner cylinder, it is incubated effect
Fruit is bad.In addition, anti-corrosion, service life is not short for pipeline in existing pipeline heat-insulating technology.
The content of the invention
The technical problems to be solved by the invention be existing petroleum pipeline in order to be incubated, generally using heat-insulation layer reduce pipe
Interior oil heat is scattered and disappeared, and still, it comes with some shortcomings, the heavier mass of bitumen layer, and the load of pipeline is increased weight, and is incubated
It is air between layer and inner cylinder, its heat insulation effect is bad.In addition, pipeline not anti-corrosion in existing pipeline heat-insulating technology, uses the longevity
Order short, and it is an object of the present invention to provide improving the petroleum pipeline of corrosion-resistant thermal insulation, pass through special structure so that pipeline has good guarantor
Warm nature energy, oil can be avoided to block, improve the convenience of oil transportation, and pipeline saves bitumen layer, using the guarantor of lightweight
Adiabator, quality is substantially reduced, reduce pipeline burden, strengthen the stability of petroleum pipeline structure, and be provided with anticorrosive coat, greatly
The big antiseptic property for improving pipeline, but also preliminary filtering can be carried out to the oil of conveying.
The present invention is achieved through the following technical solutions：
Improve the petroleum pipeline of corrosion-resistant thermal insulation, including interior conduit and the Outer Tube that is set in outside interior conduit, interior conduit with
From interior by being sequentially provided with heat-insulation layer and anticorrosive coat outside between Outer Tube, the interior circumferencial direction along interior conduit of the heat-insulation layer is successively
Insulating tube provided with multiple axis Yu interior conduit diameter parallel, heat-insulation layer inside holding pipe is filled with outside is incubated asbestos, in insulating tube
Provided with zigzag demarcation strip, the demarcation strip be located at insulating tube axis and by insulating tube be divided into close to interior conduit with it is remote
Two cavitys of interior conduit, foam is filled with the cavity of interior conduit, drier is filled with the cavity away from interior conduit；

Storage is connected.
The petroleum pipeline of the present invention, passes through special structure so that pipeline has good heat-insulating property, can avoid stone
Oil blocks, and improves the convenience of oil transportation, and pipeline saves bitumen layer, using the insulation material of lightweight, substantially reduces
Quality, pipeline burden is reduced, strengthens the stability of petroleum pipeline structure, and be provided with anticorrosive coat, substantially increase the anti-of pipeline
Rotten performance, but also preliminary filtering can be carried out to the oil of conveying.Between interior conduit and Outer Tube be provided with heat-insulation layer and
Anticorrosive coat, good insulation antiseptic effect can be played, wherein heat-insulation layer includes the insulating tube set gradually, passes through outside insulating tube
Filling insulation asbestos, so as to play first layer insulation effect, at the same be incubated asbestos can be tightly packed between interior conduit, will not
Air cavity is formed, foam is filled with the cavity of interior conduit in insulating tube, plays second layer insulation effect, pass through bilayer
Embedded structure, the light quality of uniformly good insulation effect, wherein asbestos and foam can be carried out to the surrounding of interior conduit
And high insulating effect, the weight of pipeline is greatly alleviated, not only alleviates the burden of pipeline itself, and causes pipeline more
It is easy to carry, insulating tube external spiral is wound with heater strip, by winding heater strip, heat caused by heater strip outside insulating tube
Lasting heating can be carried out to insulating tube, so as to be uniformly incubated to interior conduit surrounding.；Away from inner tube in insulating tube
The cavity in road is desiccant-filled, because in insulating process, can make the moisture in air by thermal coagulation, and can by drier
By moisture absorption to ensure the drying in pipeline；The material of anticorrosive coat is silicon nitride, and antiseptic property is good, is provided with interior conduit
Then filter screen, waste residue among oil are collected into residue collection device by being blocked during screen pack by blow-off pipe,
So as to improve pipeline service life, securely and reliably.
The material of anticorrosive coat is silicon nitride, and antiseptic property is good.
Waterproof layer is additionally provided with outside Outer Tube, waterproof layer is made of polyvinyl chloride so that pipeline has good waterproof
Performance and with barriering effect, it is ageing-resistant, corrosion-resistant.
The anti-caking of del is connected with two ends of draining ring, is passed through in globule that the end of draining ring is gathered etc.
The lower pointed end drippage of anti-caking, so as to be condensed on pipeline external wall beneath face.
The diameter ratio of insulating tube and interior conduit is 1:8-10, good heat insulation effect was both can guarantee that, again will not be to inner tube
Cause to bear in road.
During the use of pipeline, pipeline be generally all be embedded under, especially in winter, will necessarily cloth on tube wall
Then full water pearl congeals into ice slag icicle etc., by setting draining ring, moisture can finally collect in along draining ring to flowing down
On the end of draining ring, so as to be frozen on pipeline wall.
The residue collection device is connected to be detachably connected between Outer Tube external wall beneath, is easy to the cleaning to waste residue.
The latter half shape of the screen pack is bonded with interior conduit inwall, top half and the interior conduit inwall of screen pack
Do not contact, when guaranteeing situation about tentatively being filtered, the resistance being subject in oil motion can be reduced as far as possible.
The present invention compared with prior art, has the following advantages and advantages：
