Abstract
The invention discloses a novel oil delivery insulating pipe comprising an outer pipe and an inner pipe. The inner pipe is disposed in the center of an inner cavity of the outer pipe, while an anticorrosion layer is arranged on the inner surface of the inner pipe and a glass wool insulating layer structure is arranged on the outer surface of the inner pipe. Four cambered outer projections are evenly arranged on the outer wall of the outer pipe, and the outer periphery of each outer protrusion is wrapped with an aluminum foil reflecting layer. The inner pipe and the outer pipe are fixedly connected through stainless steel fastening tapes, and the outer end of each stainless steel fastening tape is fixed on the inner wall of the outer pipe. The novel oil delivery insulating pipe has the advantages that insulating performance and corrosion resistance of the inner pipe can be ensured; the aluminum foil reflecting layer in a projection form is arranged on the outer side of the outer pipe, the service life of the outer pipe can be prolonged, and maintenance cost is reduced greatly.
Description
Technical field
The present invention relates to technical field of petroleum extraction, relate in particular to a kind of nonpetroleum and carry heat-insulated pipe.
Background technique
At present, the pipe fitting that is applied to industries such as oil, chemical industry, electric power, boats and ships, metallurgy, machinery, weaving, food, building, pharmacy all needs to possess higher intensity, resistance to pressure, corrosion-resistant, resistance to high temperature, therefore, in technical field of petroleum extraction, in order to improve the recovery rate of crude oil, usually will carry out secondary oil recovery and tertiary oil recovery, secondary oil recovery is to recover the oil by the way of the additional strata pressure of water filling; Tertiary oil recovery is to realize by methods such as gas injection, chemistry injection, microorganism injections, because underground viscosity of thickened oil is higher, in order to make it have good flowability, the liquid that injects in the oil recovery or the temperature of gas are higher, so need pipeline to have certain insulation effect.At present, the used flow in pipes of secondary oil recovery and tertiary oil recovery is steel pipe, and this steel pipe is bimetallic tube, and heat insulation effect is not good enough, and not corrosion-resistant, and working life is short.Therefore, at above aspect, need make rational improvement.
Summary of the invention
The purpose of this invention is to provide the nonpetroleum conveying heat-insulated pipe that a kind of heat insulation effect is preferable, have multiple corrosion-resistant safeguard structure, be conducive to increase the service life, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of nonpetroleum is carried heat-insulated pipe, comprise outer tube body and interior tube body, described interior tube body is arranged at the lumen centers position of outer tube body and the internal surface of this interior tube body arranges one deck anticorrosive coat, at the outer surface of interior tube body one deck glass wool insulation layer structure is set; Described outer tube body evenly arranges four outer lug boss and the peripheral parcel of each outer lug boss one deck aluminium foil reflecting layer that have cambered surface along outer wall; Fastening steel band is fixedlyed connected and the outer end of the fastening steel band of each stainless steel is fixed on the internal face of outer tube body by stainless steel between interior tube body and outer tube body.
Correspondingly, the thickness of described glass wool insulation layer equals 2/3rds of interior tube body thickness, is provided with groove between per two adjacent outer lug boss.
Nonpetroleum of the present invention carries the beneficial effect of heat-insulated pipe to be: by the internal surface at interior tube body one deck anticorrosive coat is set, outer surface at interior tube body arranges one deck glass wool insulation layer structure again, can guarantee thermal and insulating performance and the antiseptic property of interior tube body; Simultaneously, by the form with boss the aluminium foil reflecting layer is set in the outer tube body outside, is conducive to prolong the working life of outer tube body, reduce maintenance cost greatly.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural drawing that the described nonpetroleum of the embodiment of the invention is carried heat-insulated pipe.
Among the figure: 1, outer tube body; 2, interior tube body; 3, outer lug boss; 4, aluminium foil reflecting layer; 5, anticorrosive coat; 6, glass wool insulation layer; 7, the fastening steel band of stainless steel; 8, groove.
Embodiment
As shown in Figure 1, the described nonpetroleum of the embodiment of the invention is carried heat-insulated pipe, comprise outer tube body 1 and interior tube body 2, described interior tube body 2 is arranged at the lumen centers position of outer tube body 1 and the internal surface of this interior tube body 2 arranges one deck anticorrosive coat 5, simultaneously, the thickness that one deck glass wool insulation layer 6 structure and glass wool insulation layer 6 is set again at the outer surface of interior tube body 2 equals 2/3rds of interior tube body 2 thickness; Described outer tube body 1 evenly arranges four outer lug boss 3 and each outer lug boss 3 peripheral parcel one deck aluminium foil reflecting layer 4 that have cambered surface along outer wall, be provided with groove 8 so that circuit is buried underground between per two adjacent outer lug boss 3, in addition, between interior tube body 2 and outer tube body 1 by stainless steel fastening steel band 7 fixedly connected and the outer end of the fastening steel band 7 of each stainless steel is welded on the internal face of outer tube body 1.
Claims (3)
1. a nonpetroleum is carried heat-insulated pipe, comprises outer tube body and interior tube body, it is characterized in that:
Described interior tube body is arranged at the lumen centers position of outer tube body and the internal surface of this interior tube body arranges one deck anticorrosive coat, at the outer surface of interior tube body one deck glass wool insulation layer structure is set;
Described outer tube body evenly arranges four outer lug boss and the peripheral parcel of each outer lug boss one deck aluminium foil reflecting layer that have cambered surface along outer wall;
Fastening steel band is fixedlyed connected and the outer end of the fastening steel band of each stainless steel is fixed on the internal face of outer tube body by stainless steel between interior tube body and outer tube body.
2. a kind of nonpetroleum as claimed in claim 1 is carried heat-insulated pipe, and it is characterized in that: the thickness of described glass wool insulation layer equals 2/3rds of interior tube body thickness.
3. a kind of nonpetroleum as claimed in claim 1 is carried heat-insulated pipe, it is characterized in that: be provided with groove between per two adjacent outer lug boss.
