Abstract
The utility model discloses a novel petroleum conveying heat-insulated pipe which comprises an outer pipe body and an inner pipe body. The inner pipe body is arranged at the central position of an inner cavity, a layer of anti-corrosion layer is arranged on the inner surface of the inner pipe body, a structure of a glass wool insulation heat insulation layer is arranged on the outer surface of the inner pipe body, four outer bosses with arc faces are evenly arranged on the outer pipe body along the outer wall face, a layer of aluminum foil reflecting layer wraps the periphery of each outer boss, the inner pipe body and the outer pipe body are fixedly connected through stainless steel fastening steel bands, and the outer end of each stainless steel fastening steel band is fixed on the inner wall face of the outer pipe body. The novel petroleum conveying heat-insulated pipe has the advantages that heat insulation performance and anti-corrosion performance of the inner pipe body can be ensured, meanwhile the outer side of the outer pipe body is provided with the aluminum foil reflecting layers in the form of the bosses, so that the service life of the outer pipe body is prolonged, and maintenance cost is greatly reduced.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of nonpetroleum and carries heat-insulated pipe.
Background technique
At present, the pipe fitting that is applied to the 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 to carry out secondary oil recovery and tertiary oil recovery, secondary oil recovery be by water filling addedly the way of stressor layer recover the oil; Tertiary oil recovery is to realize by methods such as gas inject, chemistry injection, microorganism injections, because underground viscosity of thickened oil is higher, in order to make it have good mobility, the liquid that injects in oil recovery or the temperature of gas are higher, so need pipeline to have certain insulation effect.At present, secondary oil recovery and tertiary oil recovery flow in pipes used 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, for above aspect, need to make rational improvement.
The model utility content
The purpose of this utility model is to provide the nonpetroleum conveying heat-insulated pipe that a kind of heat insulation effect is better, have multiple corrosion-resistant safeguard structure, be conducive to increase the service life, to solve many deficiencies of prior art.
The purpose of this utility model 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 thermal insulation separation thermosphere structure is set; Described outer tube body evenly arranges four with the outer lug boss of cambered surface and parcel one deck aluminium foil reflecting layer, each outer lug boss periphery along outer wall; Fastening steel band is fixedly connected with 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 thermal insulation separation thermosphere equals 2/3rds of interior tube body thickness, is provided with groove between every two adjacent outer lug boss.
Nonpetroleum described in the utility model 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 thermal insulation separation thermosphere 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 extend the working life of outer tube body, greatly reduce maintenance cost.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is the structural drawing that the described nonpetroleum of the utility model embodiment is carried heat-insulated pipe.
In figure: 1, outer tube body; 2, interior tube body; 3, outer lug boss; 4, aluminium foil reflecting layer; 5, anticorrosive coat; 6, glass wool thermal insulation separation thermosphere; 7, the fastening steel band of stainless steel; 8, groove.
Embodiment
As shown in Figure 1, the described nonpetroleum of the utility model embodiment 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 at the outer surface of interior tube body 2 one deck glass wool thermal insulation separation thermosphere 6 structures and glass wool thermal insulation separation thermosphere 6 is set again equals 2/3rds of interior tube body 2 thickness; Described outer tube body 1 evenly arranges four with the outer lug boss 3 of cambered surface and the peripheral parcel one deck aluminium foil of each outer lug boss 3 reflecting layer 4 along outer wall, be provided with groove 8 so that circuit is buried underground between every two adjacent outer lug boss 3, in addition, fastening steel band 7 is fixedly connected with 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 by stainless steel between interior tube body 2 and 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 thermal insulation separation thermosphere structure is set;
Described outer tube body evenly arranges four with the outer lug boss of cambered surface and parcel one deck aluminium foil reflecting layer, each outer lug boss periphery along outer wall;
Fastening steel band is fixedly connected with 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 thermal insulation separation thermosphere 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 every two adjacent outer lug boss.
