Oil and gas pipeline protection device

Abstract

The middle mold of the oil and gas pipeline protection device comprises a cement base used for containing an oil and gas pipeline, a first protection cover and a second protection cover, the first protection cover is a hard plastic plate, the two ends of the first protection cover are erected at the top ends of supporting arms of a U-shaped structure respectively, and a first closed space is formed by the first protection cover and an inner cavity of the U-shaped structure; the second protection cover is a steel box body, a second closed space is formed in the steel box body, the steel box body is of an arc-shaped structure, the inner wall of the arc-shaped structure is matched with the outer wall of the oil and gas pipeline, and a buffer spring is arranged on the inner wall of the arc-shaped structure; the first closed space and the second closed space are respectively filled with warning smog with different colors; the mode that the first protection cover and the second protection cover are arranged outside the oil and gas pipeline is adopted, the technical purpose of double-layer protection is achieved on the basis of the arrangement of the double-layer protection cover, meanwhile, the double-layer protection cover is filled with warning smog of different colors, and the technical purpose of multi-type warning is achieved.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline protection equipment, in particular to an oil and gas pipeline protection device. Background technique [0002] At present, my country's oil and gas pipeline transportation has covered regional crude oil pipeline networks in Northeast China, North China, Central South China, East China and Northwest China. At the same time, the connection with foreign pipelines is also a major progress in my country. as follows: [0003] First, the hidden danger of pipeline corrosion: the buried environment of the pipeline is generally poor, buried in the soil, the various factors and the properties of the medium around the pipeline are very different, which brings great difficulty to the anti-corrosion work of the pipeline . The problem of pipeline corrosion is mainly affected by the following aspects: the influence of temperature, mainly refers to the temperature of the pipeline itself during the t...

Problems solved by technology

[0004] Second, hidden dangers of pipeline damage: Since oil and natural gas pipelines are mostly laid in the wild, real-time monitoring cannot be achieved. In the event of unexpected situations such as landslides, earthquakes, rockfall, third-party construction damage and other accidents, there may be damage to the pipeline. Pipelines cause damage, leading to damage to pipelines, resulting in oil and gas leakage that pollutes the environment and even triggers explosions that cause property losses and casualties. Therefore, it is necessary to take some protective measures for oil and gas pipelines to reduce accident hazards

[0007] First, in the prior art, only one layer of protective device is installed outside the oil and gas pipeline, and its protective force is insufficient;

[0008] Second, only one colored smoke is set in the existing technology, which can only represent a situation and cannot be finely sealed and controlled
