Description

technical field [0001] The invention relates to a detection instrument, in particular to a pipeline internal corrosion detection device and a detection method thereof. Background technique [0002] Pipeline transportation is an economical, efficient, clean and safe way to solve energy transportation problems. At present, the pipeline has become a huge oil and gas energy transportation tool in the world. The production fluid of oil and gas fields is usually a mixture of oil, water and gas, and the corrosive medium (such as H 2 S, CO 2 etc.) are highly corrosive to oil and gas pipelines, and are likely to cause corrosion of pipelines, resulting in leakage of produced fluid and even explosion of pipelines. If you can master the corrosion mechanism and laws of corrosive media and understand the corrosion of pipelines, you can take effective measures to avoid dangerous accidents. However, the current on-site acquisition of pipeline corrosion technology is still immature, such...
