Abstract
The invention discloses an insulation oil pipe with inside and outside reinforcing rib structures. The insulation oil pipe comprises an outer pipe body and an inner pipe body. An erosion-resistant coating is arranged on the inner wall of the inner pipe body, a glass wool insulation layer is arranged between the inner surface of the inner pipe body and the erosion-resistant coating, a plurality of inner bosses are additionally arranged on the outer wall of the inner pipe body, and each inner boss penetrates out of the outer surface of the glass wool insulation layer. The outer surface of the outer pipe body is provided with a plurality of arc-shaped steel belts, and six line grooves are uniformly formed in a cavity between the inner pipe body and the outer pipe body. The insulation oil pipe with the inside and outside reinforcing rib structures has the advantages that insulation and erosion-resistant performances of the inner pipe body can be strengthened by the arrangement, six leakage alarm lines with protective shells are arranged between the inner pipe body and the outer pipe body, and safe operation of a heat supply network can be guaranteed; meanwhile, since the inner bosses are additionally arranged on the outer wall of the inner pipe body and the arc-shaped steel belts are arranged on the outer surface of the outer pipe body, service life of the outer pipe body is beneficially prolonged, and cost in maintenance is greatly reduced.
Description
Technical field
The present invention relates to technical field of petroleum extraction, relate in particular to a kind of insulation 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 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 takes place in the pipeline somewhere, by the conduction of alarm line, just can report alert and demonstrate the accurate position that leaks and the size of seepage degree in the dedicated test instrument, in order to notify the maintainer to handle the pipeline section that leaks rapidly, 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 inadequately, also need to set up the necessary protection structure.Therefore, at above aspect, need make rational improvement.
Summary of the invention
The purpose of this invention is to provide the insulation petroleum pipeline with inside and outside reinforcing rib structure that a kind of heat insulation effect is preferable, have Multiple Protective Structure, adopt built-in wire casing structure, 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 insulation 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 insulation layer is set, sets up some inner convex platforms and each inner convex platform on the described interior tube body outer wall and pass glass wool insulation layer outer surface; Described outer tube body outer surface is provided with some arc steel bands, 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 insulation petroleum pipeline of inside and outside reinforcing rib structure of the present invention is: by the internal surface at interior tube body glass wool insulation layer is set, can strengthen thermal and insulating performance, the antiseptic property of interior tube body, the leakage alarm line that the six roots of sensation has containment vessel is set between interior tube body and outer tube body, can guarantees the heat supply network safe operation; Simultaneously, set up some inner convex platforms in the interior tube body outer wall, the outer tube body outer surface is provided with some arc steel bands, is conducive to prolong the working life of outer tube body, reduces maintenance cost greatly.
