The reporter learned from CNOOC on the 16th that the submarine pipeline magnetic flux leakage detector independently developed by our country was successfully tested by sea in the bz34-1 oil field in Bohai Sea and obtained complete and valid data. The performance parameters of the detector reached the international similar products The advanced level marks the end of the era of ocean detection in China's submarine pipeline.
Magnetic flux leakage testing is currently the most mature and most widely used in the industry pipeline detection technology, this technology can detect corrosion inside the outer wall, mechanical damage and other metal loss defects. Expected end of this year or early next year, the detector can be initially realized industrialization. Submarine pipeline will usher in our own "medical doctor."
