Abstract
The utility model discloses an improved pipeline for oil exploitation. The improved pipeline is characterized by comprising an inner pipe and an outer pipe which is sleeved outside the inner pipe. Two ends of the outer pipe are respectively provided with a connector. A heat preservation layer is arranged between the inner pipe and the outer pipe. A thermal insulating layer is arranged outside the heat preservation layer. An anti-corrosion layer is arranged on the inner wall of the inner pipe. The improved pipeline for oil exploitation has the advantages of reasonable structure, good heat preservation effects, long service life and low cost.
Description
Technical field
The utility model relates to a kind of oil exploration equipment, relates in particular to a kind of improved pipeline for petroleum production.
Background technique
In field of petroleum exploitation, pipeline is a kind of equipment that must use.The pipeline that uses on the oil field at present exists Heavy Weight, and transportation and carrying are inconvenient, and working life is short, and heat insulation effect is poor, causes serious heat loss, consumes in a large number the energy, has improved cost of production.Can not satisfy user's user demand.Therefore, should provide a kind of new technological scheme to address the above problem.
The model utility content
The purpose of this utility model is: for above-mentioned deficiency, provide a kind of rational in infrastructure, high insulating effect, working life is of a specified duration, cost is low improved pipeline for petroleum production.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of improved pipeline for petroleum production, comprise inner tube and the outer tube that is sheathed on the inner tube outside, the two ends of described outer tube are provided with joint, are provided with thermal insulation layer between the described inner and outer tubes, the outside of described thermal insulation layer is provided with thermal-protective coating, and the inwall of described inner tube is provided with corrosion-resistant coating.
The outside of described outer tube is provided with protective layer.
Described protective layer is plastic protective film for plastics.
Described thermal insulation layer is polyurethane insulation coating.
Described joint is soldered splice.
Described corrosion-resistant coating is the composite film of titanium silicon nitride.
A kind of improved pipeline for petroleum production of the utility model, between inner and outer tubes, be provided with thermal insulation layer, outside at thermal insulation layer is provided with thermal-protective coating, have on the one hand the effect that insulation prevents that heat runs off, the setting of thermal-protective coating also is conducive to transportation and the movement of the utility model pipeline on the other hand.Inwall in inner tube is provided with corrosion-resistant coating, and it can be avoided long-term use of inner tube and be corroded, and prolongs its working life, economizes on resources, and reduces production costs.Outside at outer tube is provided with protective layer, can prolong the working life of pipeline, reduces cost.
The utility model has the advantages that: rational in infrastructure, high insulating effect, working life is of a specified duration, cost is low.
