technical field

The invention relates to a pipeline detection device, in particular to a petroleum pipeline detection device for detecting whether the petroleum pipeline is deformed.

Background technique

At present, my country is laying new pipelines at a speed of 1000-2000km/a. As a long-distance transportation facility for natural gas, oil and other media, pipelines are laid in various environments such as land and sea around the world. Most oil and gas pipelines are buried pipelines. Due to the influence of internal and external forces such as earthquakes, stratum movement, crustal changes, heat transfer deformation, and third-party construction damage, pipelines often deform to varying degrees, such as pipeline depressions and elliptical deformations. , pipe bending or sinking and other problems. These deformations will increase the oil transportation resistance, resulting in a decrease in the oil and gas transmission rate. In order to maintain the normal oil transportation volume, it will increase the energy consumption of the oil transportation process; at the same time, the deformation will also cause the pipeline strength to decrease, the pipe shape to change, and form a safety hazard. . If the maintenance cannot be detected in time, it may cause the pipeline to rupture, resulting in production stoppage, resulting in irreparable economic losses. In order to ensure the normal transmission of oil and gas pipelines, it is necessary to monitor the deformation of oil and gas pipelines, which requires the design of an oil pipeline detection device suitable for oil and gas pipeline detection.
