Abstract
The utility model discloses a multi-trunking petroleum pipeline structure which comprises an outer pipe body and an inner pipe body. The inner pipe body is arranged in the center of the inner cavity of the outer pipe body, a glass wool heat preservation and insulation layer is further arranged on the outer surface of the inner pipe body, the outer surface of the outer pipe body is sleeved with a glass fiber reinforced plastic protection shell, a plastic protective film layer is arranged on the outer layer of the glass fiber reinforced plastic protection shell, and six leakage warning lines with protective shells are evenly arranged in the cavity between the inner pipe body and the outer pipe body. The multi-trunking petroleum pipeline structure has the advantages that due to the fact that the glass wool heat preservation and insulation layer is arranged on the outer surface of the inner pipe body, the heat preservation and insulation performance and the antiseptic performance of the inner pipe body can be guaranteed; due to the fact that the six leakage warning lines with the protective shells are arranged between the inner pipe body and the outer pipe body, a heat supply network can be guaranteed to operate safely; meanwhile, the glass fiber reinforced plastic protection shell and the plastic protective film layer are additionally arranged outside the outer pipe body, prolonging of the service life of the outer pipe body is facilitated, and maintenance cost is greatly lowered.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of multiple trunking petroleum pipeline structure.
Background technology
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 elevated temperatures, therefore, in technical field of petroleum extraction, in order to improve the recovery ratio 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.When making the high temperature prefabricated direct-buried thermal insulation pipe, in the close insulation layer of steel pipe, be embedded with alarming line, in case seepage occurs in the pipeline somewhere, conduction by alarm line, just can report in the dedicated test instrument and warn and demonstrate the accurate location that leaks and the size of seepage degree, in order to notify the maintainer to process rapidly the pipeline section that leaks, guarantee the heat supply network safe operation.But at present, this steel pipe heat insulation effect is not good enough, and not corrosion-resistant, and application life is short; Particularly wire casing arrange rationally not, also need to set up necessary safeguard structure.Therefore, for above aspect, need to make rational improvement.
The utility model content
The purpose of this utility model is to provide the multiple trunking petroleum pipeline structure that a kind of heat insulation effect is better, have Multiple Protective Structure, adopt built-in wire casing 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 multiple trunking petroleum pipeline structure; comprise outer tube body and interior tube body; described interior tube body is arranged at the lumen centers position of outer tube body; external surface at interior tube body arranges one deck glass wool thermal insulation separation thermosphere; described outer tube body appearance surface cover has the glass fiber reinforced plastic containment vessel and in this glass fiber reinforced plastic containment vessel skin, the plastic protective film for plastics layer is set, and the six roots of sensation evenly is set with the leakage alarm line of containment vessel in the cavity between interior tube body and outer tube body.
The inner surface of described interior tube body arranges one deck anticorrosive coat, and the thickness of glass fiber reinforced plastic containment vessel and plastic protective film for plastics layer is 2.5cm-4cm.
The beneficial effect of multiple trunking petroleum pipeline structure described in the utility model is: by the external surface at interior tube body, glass wool thermal insulation separation thermosphere is set, can guarantee thermal and insulating performance, the antiseptic property of interior tube body, the six roots of sensation is set with the leakage alarm line of containment vessel between interior tube body and outer tube body, can guarantees the heat supply network safe operation; Simultaneously, set up glass fiber reinforced plastic containment vessel and plastic protective film for plastics layer in the outer tube body outside, be conducive to extend the application 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 described multiple trunking petroleum pipeline of the utility model embodiment structure chart.
In figure: 1, outer tube body; 2, interior tube body; 3, plastic protective film for plastics layer; 4, glass fiber reinforced plastic containment vessel; 5, anticorrosive coat; 6, glass wool thermal insulation separation thermosphere; 7, leakage alarm line.
The specific embodiment
as shown in Figure 1, the described multiple trunking petroleum pipeline of the utility model embodiment structure, 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 inner surface of this interior tube body 2 arranges one deck anticorrosive coat 5, simultaneously, external surface at interior tube body 2 arranges one deck glass wool thermal insulation separation thermosphere 6 again, what need that emphasis mentions is, described outer tube body 1 appearance surface cover has glass fiber reinforced plastic containment vessel 4 and in these glass fiber reinforced plastic containment vessel 4 skins, plastic protective film for plastics layer 3 is set, in addition, the six roots of sensation evenly is set with the leakage alarm line 7 of containment vessel in the cavity between interior tube body 2 and outer tube body 1, glass fiber reinforced plastic containment vessel 4 wherein is 2.5cm with the thickness of plastic protective film for plastics layer 3, arbitrary value between 4cm or 2.5cm-4cm.
Claims (3)
1. a multiple trunking petroleum pipeline structure, comprise outer tube body and interior tube body, it is characterized in that:
