Insulation oil pipe with inside and outside reinforcing rib structures

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 [0001] The invention relates to the technical field of petroleum exploitation, in particular to a heat-insulating petroleum pipe with internal and external reinforcing rib structures. Background technique [0002] At present, pipe fittings used in petroleum, chemical, electric power, shipbuilding, metallurgy, machinery, textiles, food, construction, pharmaceuticals and other industries need to have high strength, pressure resistance, corrosion resistance, and high temperature resistance. In the field of mining technology, in order to improve the oil recovery rate of oil fields, secondary oil recovery and tertiary oil recovery are usually carried out. At the same time, when high-temperature prefabricated direct-buried insulation pipes are manufactured, an alarm line is embedded in the insulation layer near the steel pipe. A leak occurs in a certain part of the pipeline. Through the conduction of the alarm line, an alarm can be displayed on the special detection ins...

AI Technical Summary

Problems solved by technology

But at present, this kind of steel pipe has poor insulation effect, is not corrosion-resistant, and has a short service life; especially the setting of the trunking is not reasonable enough, and necessary protective structures need to be added
