Conduct a survey of buried pipelines in the storage and transportation department of Guangzhou Petrochemical Company to determine the location, depth, direction, and degree of anti-corrosion coating of the buried pipelines. For buried pipelines with sleeves, use MsS ultrasonic guided wave technology to detect changes in metal wall loss of the buried pipelines.

Leakage detection was carried out on the buried pipelines of the Jiujiang Petrochemical Oil Storage and Transportation Operations Department. High sensitivity specialized sensors, high-precision 12 bit AD sampling, 1-6400 times programmable gain amplifiers were used to adapt to various strong and weak leakage signal detection, and GPS synchronous data acquisition was used to achieve precise positioning.
