Abstract

The utility model belongs to the technical field of hoses, in particular discloses a composite conductive hose which adopts the technical scheme by comprising a thermal medium conduit made of nylon. The outer side surface of the thermal medium conduit is sequentially wrapped by an insulating layer, a high-strength wrapping layer and an abrasion-resisting and erosion-resisting outer surface layer, wherein the insulating layer is formed by winding and sticking glass fibers, a tetrafluoro adhesive tape and an adhesive, and the high-strength wrapping layer is formed by weaving polyester industrial filaments. The composite conductive hose overcomes the defects that the prior pipeline used in petroleum extraction for conveying hot water or other thermal mediums has low mechanical strength and can not simultaneously satisfy the requirements for insulating performance, and the composite conductive hose has the advantages of rapid conveying for hot water or other thermal mediums, high mechanical strength, as well as abrasion, high temperature and erosion resistance and long service life.

Description

A kind of composite heat-conducting flexible pipe

Technical field

The utility model belongs to technical field of hoses, relates to a kind of composite heat-conducting flexible pipe that delivering hot water and other thermal medium have certain intensity in the petroleum production that is used in concretely.

Background technique

At present, both at home and abroad the oil field to high, coagulate, the difficult problem of consistency crude oil ubiquity exploitation, reason is to contain a large amount of asphalt colloids, cured matter etc. in crude oil, and its solidifying point is raise, in the lifting process its temperature can reduce gradually and produce knot cured, solidify, problem such as obstruction, can't ordinary production.In order to address the above problem, adopt to wherein logical as hot water or other thermal mediums heat eliminate above-mentioned knot cured, solidify, problem such as obstruction.But since the pipeline of logical as hot water or thermal medium be metal tube or plastic pipe because the length of pipeline is between hundreds of meters; Therefore, use metallic conduit owing to itself do not have the performance of insulation, produce when hot water also arrives that knot is cured, during the pipeline section that solidifies, stop up, the temperature of hot water or thermal medium can not reach melts the effect cured, that solidify of tying; Use general plastic tube to there is the defective that mechanical strength is low, thermal insulation property can not be satisfied the demand.

The model utility content

The purpose of this utility model just provides a kind of good heat insulating, mechanical strength is high, is used in the composite heat-conducting flexible pipe of delivering hot water and other thermal medium degree in the petroleum production

For achieving the above object, the technological scheme that the utility model adopted is:

A kind of composite heat-conducting flexible pipe, include the thermal medium conduit that constitutes by nylon, the outer side surface of this thermal medium conduit be enclosed with successively by glass fibre and tetrafluoro adhesive tape and tackiness agent twine the thermal insulation layer that is bonded, the high strength coating that is woven into by polyester industrial yarn and have wear-resisting, corrosion resistant external layer.

In addition, the caliber of described thermal medium conduit is 15-20 millimeters, and the thickness of its tube wall is 1.0-1.5 millimeters; The thickness of described thermal insulation layer, high strength layer and external layer is followed successively by 1.0 ± 0.1 millimeters, 0.7 1 0.8 millimeters and 0.7-0.8 millimeter.

Composite heat-conducting flexible pipe provided by the utility model, compared with prior art have the following advantages: one, adopt nylon material to constitute owing to constitute the conduit that is used for delivering hot water or other thermal mediums of this composite heat-conducting flexible pipe, this nylon material has molecular weight height, characteristics that density is high, formed duct wall has smooth less scaling, so delivering hot water or other thermal mediums have the fast characteristics that transmit; Its two twine the thermal insulation layer that is bonded owing on the outer wall of the conduit that above-mentioned nylon material constitutes, be bonded with one deck by glass fibre and tetrafluoro adhesive tape and tackiness agent, so this pipe has the high characteristics of heat transfer efficiency, promptly heat loss is lower in the process that transmits; They are three years old, owing to be enclosed with the high strength coating that is woven into by polyester industrial yarn in the outside of above-mentioned thermal insulation layer, therefore the composite heat-conducting flexible pipe that is constituted has the mechanical strength of higher tension and resistance to compression characteristics, can satisfy the High Temperature High Pressure hot water of long distance or the conduction of other thermal mediums; Its four have wear-resisting, the corrosion resistant external layer that constitutes by nylon material owing to be coated with in the outside of above-mentioned high strength coating, make the composite heat-conducting flexible pipe have wear-resisting, high temperature resistant and corrosion resistant performance, improved its working life.

Description of drawings

Accompanying drawing is the structural representation of composite heat-conducting flexible pipe provided by the utility model.

Embodiment

Be described further below in conjunction with the structure of accompanying drawing the composite heat-conducting flexible pipe that the utility model proposed.

The thickness that the structure of this composite heat-conducting flexible pipe includes the tube wall that is made of nylon is that 1.0-1.5 millimeters, caliber are 15-20 millimeters thermal medium conduit 1, the outer side surface of this thermal medium conduit be enclosed with successively by total thickness be 1.0 ± 0.1 millimeters glass fibres and tetrafluoro adhesive tape by tackiness agent twine the thermal insulation layer 2 that is bonded, the thickness that is woven into by polyester industrial yarn is that 0.7-0.8 millimeter high strength coating 3 and thickness is wear-resisting, the corrosion resistant external layer 4 that is made of nylon material of 0.7-0.8 millimeter have.

After testing, the above-mentioned composite heat-conducting flexible pipe that utilizes 600 meters is when transmitting hot water, and when flow velocity during at 0.1 meter per second, its heat loss only is 0.5---1.0 left and right sides %.
