The vacuum compound heat insulating pipe has the heat insulating life of more than eight years, and the heat insulating effect can be ensured. In addition, when theinner pipe and the outer pipe of the vacuum compound heat insulating pipe are damaged, the stainless steel vacuum heat insulating pipe is conveniently replaced, can be repeatedly used and reduces themaintenance cost in a subsequent maintenance process.
Description
Technical field
The present invention relates to heat insulating tube, relate in particular to a kind of vacuum composite heat-insulating, be applicable to that the insulation of liquid, gas is carried, be specially adapted to the down-hole oil tube of thick oil filling steam, oil recovery usefulness, this vacuum composite heat-insulating can reduce annotates evaporation loss, improves heat energy utilization.
Background technique
The oil pipe operated by rotary motion of using is in the down-hole of km at present, because well depth, oil is thick, the down-hole heat transfer temperature difference is big, and the steel pipe thermal conductivity is higher, and heat loss is very big during steam injection in oil pipe, and this for this reason oil pipe must adopt the superior insulated tubing of heat-shielding performance.Existing insulated tubing insulation system is usually based on thermal-protective materials such as glass wool, aluminium silicate wools, be aided with aluminium foil, glass cloth etc., and after vacuumizing, charge into the inert gas of low thermal conductivity, and the thermal conductivity of this insulated tubing is higher, and heat-shielding performance is difficult to permanent maintenance.
Vacuum multilayer insulation technology in cryogenic engineering and the use of space flight department, though it is very ripe, but apply it on the insulated tubing and be not easy, because, insulated tubing is to work under High Temperature High Pressure, and working environment is very disliked slightly, and itself is not only thin but also long, obtain and keep very difficulty of vacuum for a long time, it is very big to make difficulty of processing.Chinese patent CN2410410 discloses a kind of name and has been called " viscous crude is adopted the double-purpose energy-saving oil pipe with efficient the notes " utility model patent, and this patent adopts the screening heat shielding is set between inner and outer pipes equally spacedly, and each hides the mode that is connected and vacuumized by connecting ring between the heat shielding.It is more that this patent respectively hides between the heat shielding link, and inner and outer pipes is carbon steel venting easily under High Temperature High Pressure, and degree of vacuum is difficult to permanent maintenance, causes the heat insulation life-span of heat insulating tube not long.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to solve the deficiency that the above-mentioned background technology exists, and makes easy processing, good heat-insulation effect, the vacuum composite heat-insulating that the heat insulation life-span is long.
For achieving the above object, the present invention adopts following technological scheme: vacuum composite heat-insulating, pipe and outer tube in comprising, it is characterized in that between inner and outer pipe, being provided with independent stainless steel or the carbon steel vacuum heat insulation tube of one deck at least, the double-deck vacuum-pumping tube of this vacuum heat insulation tube for only being welded with corrosion resistant plate or carbon steel board.
In such scheme, described vacuum heat insulation tube between inner and outer pipe can be spliced vertically by at least two joints.In this case, the wall thickness of vacuum heat insulation tube is more than or equal to 0.3 millimeter; Length greater than 500 millimeters, less than 5000 millimeters.
In such scheme, described vacuum heat insulation tube between inner and outer pipe also can be made of one joint.In this case, the wall thickness of vacuum heat insulation tube is more than or equal to 0.3 millimeter.
In such scheme, can be provided with the gap between described vacuum heat insulation tube and the inner and outer pipe, this gap can be filled heat preserving and insulating material, filling with inert gas or be vacuumized.
In such scheme, the degree of vacuum of described vacuum heat insulation tube preferably is higher than 1 * 10
-1Pa.
In such scheme, can be placed with getter in the described vacuum heat insulation tube.
In such scheme, between outer tube wall and vacuum heat-insulation tube outer surface, can be provided with centering ring.
In such scheme, can scribble insulating moulding coating at the outer wall of interior pipe, the inwall of outer tube.
Because the present invention is provided with independent stainless-steel vacuum heat insulating tube between inner and outer pipes, its effect of heat insulation and life-span depend primarily on the stainless-steel vacuum heat insulating tube, and the stainless-steel vacuum heat insulating tube is made easy processing, condition of high vacuum degree guarantees easily, therefore, the heat insulation life-span of vacuum composite heat-insulating of the present invention can reach more than 8 years, and effect of heat insulation can guarantee.
In addition, because stainless-steel vacuum heat insulating tube of the present invention is independent with sliceable, therefore, when the inner and outer pipes of vacuum composite heat-insulating damaged, in the maintenance process in later stage, the stainless-steel vacuum heat insulating tube was changed convenient, can reuse, reduce maintenance cost.
