Abstract
The utility model discloses a thermal insulating petroleum pipe with an internal and external reinforcing rib structure. The thermal insulating petroleum pipe comprises an external pipe body and an internal pipe body. An erosion-resistant layer is arranged on the inner wall face of the internal pipe body. A glass wool thermal insulating layer is arranged between the inner surface of the internal pipe body and the erosion-resistant layer. The outer wall face of the internal pipe body is additionally provided with a plurality of inner bosses and each inner boss penetrates through the outer surface of the glass wool thermal insulating layer. The outer surface of the external pipe body is provided with a plurality of arc-shaped steel belts. Six trunkings are evenly formed in a cavity between the internal pipe body and the external pipe body. The thermal insulating petroleum pipe with the internal and external reinforcing rib structure has the advantages that the thermal insulating performance and the erosion-resistance performance of the internal pipe body can be enhanced; due to the fact that six leakage warning wires with protective shells are arranged between the internal pipe body and the external pipe body, the safety of running of a heat supply network can be guaranteed; meanwhile, due to the fact that the inner bosses are additionally arranged on the outer wall face of the internal pipe body and the arc-shaped steel belts are arranged on the outer surface of the external pipe body, prolonging of the service life of the external pipe body is facilitated 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 thermal insulatnig petroleum pipeline with inside and outside reinforcing rib structure.
Background technique
at present, be applied to oil, chemical industry, electric power, boats and ships, metallurgical, machinery, weaving, food, building, the pipe fitting of the industries such as 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, simultaneously, when making the high temperature prefabricated direct-buried thermal insulation pipe, in the close thermal 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 working 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 model utility content
The purpose of this utility model is to provide the thermal insulatnig petroleum pipeline with inside and outside reinforcing rib 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 thermal insulatnig petroleum pipeline with inside and outside reinforcing rib structure, comprise outer tube body and interior tube body, described interior tube body internal face arranges one deck anticorrosive coat, between the internal surface of interior tube body and anticorrosive coat, one deck glass wool thermal insulation separation thermosphere is set, sets up some inner convex platforms and each inner convex platform on described interior tube body outer wall and pass glass wool thermal insulation separation thermosphere outer surface; Described outer tube body outer surface is provided with some arc-shaped steel belts, and six wire casings evenly are set in the cavity between interior tube body and outer tube body.
The leakage alarm line is equipped with in each wire casing inside, and described inner convex platform cross section is rectangular configuration.
Beneficial effect with thermal insulatnig petroleum pipeline of inside and outside reinforcing rib structure described in the utility model is: by the internal surface at interior tube body, glass wool thermal insulation separation thermosphere is set, can strengthen 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 some inner convex platforms on the interior tube body outer wall, the outer tube body outer surface is provided with some arc-shaped steel belts, is conducive to extend the working life of outer tube body, greatly reduces maintenance cost.
