Abstract
The invention discloses a heat-insulating petroleum pipe with in-built double channels. The heat-insulating petroleum pipe comprises an outer pipe body and an inner pipe body. A layer of steel jacket is arranged in the middle of an inner cavity of the outer pipe body. A plastic protective film layer is wrapped on the outer surface of the outer pipe body. A steel plate is fixedly mounted inside the steel jacket and divides the inner portion of the steel jacket into two cavities with different space and sizes. The inner pipe body and a detachable inner pipe are mounted on the two cavities respectively, and the pipe diameter of the inner pipe body is twice that of the detachable inner pipe. The heat-insulating petroleum pipe has the advantages that the plastic protective film layer is wrapped on the outer surface of the outer pipe body, so that anticorrosive and antioxidative properties of the outer pipe body can be improved; the inner portion of the steel jacket is divided into the two cavities with the different space and sizes, and the inner pipe body and the detachable inner pipe are mounted in the cavities respectively, so that a double-channel structure is facilitated to be provided, project amount and cost are saved, service life of the inner pipe body is prolonged and maintenance cost is greatly reduced.
Description
Technical field
The present invention relates to technical field of petroleum extraction, relate in particular to a kind of built-in Twin channel insulation petroleum pipeline.
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 need to possess higher intensity, resistance to pressure, corrosion-resistant, resistance to high temperature.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, 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, thermal insulation pipe is used for the conveying of liquid, gas and other media.At present, this steel pipe heat insulation effect is not good enough, and not corrosion-resistant, and working life is short; It is reasonable inadequately that the protection structure of special outer tube body arranges, also different for the laying of different application scene pipeline along with the fast development of oil exploitation technology simultaneously, needs sometimes to dispose twin-channel structure so that save engineering work load and cost.Therefore, at above aspect, need make rational improvement.
Summary of the invention
The purpose of this invention is to provide the built-in Twin channel insulation petroleum pipeline that a kind of heat insulation effect is preferable, have Multiple Protective Structure, be convenient to dismounting, 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 built-in Twin channel insulation petroleum pipeline comprises outer tube body and interior tube body, and the internal cavities center position of described outer tube body arranges one deck steel bushing, is positioned at outer surface parcel one deck plastic protective film for plastics layer of outer tube body; Described steel bushing internal fixation is installed by one block plate and this steel plate is divided into the chamber that two spaces vary in size with steel bushing inside, and interior tube body, dismountable interior pipe are installed in the twice that two chambers caliber interior and interior tube body equals dismountable inner tube diameter respectively; Lay 12 cylindrical reinforcing bars in the separate space between interior tube body and outer tube body.
Described interior tube body, dismountable inner tube wall face arrange one deck anticorrosive coat respectively, and every cylindrical reinforcing bar outer race has anti-skidding containment vessel.
The beneficial effect of built-in Twin channel insulation petroleum pipeline of the present invention is: at the outer surface parcel plastic protective film for plastics layer of outer tube body, can improve antiseptic property and the oxidation resistance of outer tube body; Steel bushing inside is divided into the chamber that two spaces vary in size, and interior tube body, dismountable interior pipe are installed respectively in two chambers, is beneficial to the twin-channel structure of configuration so that save engineering work load and cost, prolongs the working life of interior tube body, reduces maintenance cost greatly.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
