It mainly consists of the pipeline itself, pipeline accessories, and various devices on the pipeline. The main function of oil and gas pipelines is to transport oil and gas from the extraction site to the consumption site to ensure the supply of oil and gas. These pipelines usually span long distances and can be onshore pipelines or offshore pipelines, with the characteristics of efficient, safe, and reliable transportation. During the use of oil and gas pipelines, pipeline detection devices are required to perform non-destructive detection on them.

[0045] The working principle and usage process of the present utility model: When in use, first put the two mounting frames 1 on the surface of the oil and gas pipeline, and use the fixing bolts 5 to fix them in the mounting holes 4 on the two mounting parts 3. Then, by starting the two electric push rods 6, the two arc-shaped detection pliers 7 can be pushed to move towards each other, so that the two arc-shaped detection pliers 7 can be attached to the oil and gas pipeline. At this time, the magnetic attraction arc-shaped frame 14 is magnetically attracted to the oil and gas pipeline, the sealing gasket 15 is closely attached to the oil and gas pipeline, and at the same time, the convex block 17 is clamped into the groove 16, so that an airtight detection area can be formed in the air pressure chamber 8. Then, start the air extraction pump 11 to make the air extraction valve 9 extract air from the air pressure chamber 8. After the air extraction is completed, turn off the air extraction pump 11, and then check the air pressure change in the air pressure chamber 8 through the air pressure detector 10. If there is an air leakage crack in the oil and gas pipeline, the air pressure will gradually increase, so as to judge whether the pipeline is damaged, and then start the warning light 18 to prompt the staff to maintain it. After the surface detection of this area of the oil and gas pipeline is completed, only need to start the electric push rod 6 to drive the arc-shaped detection pliers 7 to retract into the storage groove 2, without removing the mounting frame 1. Then, only need to slide the mounting frame 1 to the next detection area of the oil and gas pipeline through the handle, and then detect this detection area in the same way.
