Abstract
The present invention discloses 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, one deck glass wool heat insulation layer is set between the internal surface and anticorrosive coat of interior tube body, described interior tube body outer wall sets up some inner convex platforms and each inner convex platform through glass wool heat insulation layer outer surface; Described outer tube body outer surface is provided with some arc-shaped steel belts, evenly arranges six wire casings in the cavity between interior tube body and outer tube body.Beneficial effect of the present invention is: can strengthen the thermal and insulating performance of interior tube body, antiseptic property, arranges the leakage alarm line of the six roots of sensation with containment vessel, can ensure heat supply network safe operation between interior tube body and outer tube body; Meanwhile, interior tube body outer wall sets up some inner convex platforms, outer tube body outer surface is provided with some arc-shaped steel belts, is conducive to the working life extending outer tube body, greatly reduces maintenance cost.
Description
Technical field
The present invention relates to technical field of petroleum extraction, particularly relate 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 secondary oil recovery and tertiary oil recovery will be carried out, simultaneously, when manufacturing high temperature prefabricated direct-buried thermal insulation pipe, in the thermal insulation layer near steel pipe, be embedded with alarming line, once there is seepage in pipeline somewhere, by the conduction of alarm line, just can report in dedicated test instrument and warn and demonstrate the size of accurate location and the leak magnitude leaked, to notify that maintainer processes rapidly the pipeline section leaked, ensure 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 not unreasonable, also need to set up necessary safeguard structure.Therefore, for above aspect, need to make rational improvement.
Summary of the invention
The object of this invention is to provide a kind of heat insulation effect better, there is Multiple Protective Structure, adopt built-in wire casing structure, be conducive to the thermal insulatnig petroleum pipeline with inside and outside reinforcing rib structure that increases the service life, to solve many deficiencies of prior art.
Object of the present invention carrys out 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, one deck glass wool heat insulation layer is set between the internal surface and anticorrosive coat of interior tube body, described interior tube body outer wall sets up some inner convex platforms and each inner convex platform through glass wool heat insulation layer outer surface; Described outer tube body outer surface is provided with some arc-shaped steel belts, evenly arranges six wire casings in the cavity between interior tube body and outer tube body.
Leakage alarm line is equipped with in each wire casing inside, and described inner convex platform cross section is rectangular configuration.
The beneficial effect with the thermal insulatnig petroleum pipeline of inside and outside reinforcing rib structure of the present invention is: by arranging glass wool heat insulation layer at the internal surface of interior tube body, the thermal and insulating performance of interior tube body, antiseptic property can be strengthened, the leakage alarm line of the six roots of sensation with containment vessel is set between interior tube body and outer tube body, heat supply network safe operation can be ensured; Meanwhile, interior tube body outer wall sets up some inner convex platforms, outer tube body outer surface is provided with some arc-shaped steel belts, is conducive to the working life extending outer tube body, greatly reduces maintenance cost.
Accompanying drawing explanation
