MICRO PIPELINE CORROSION EDDY CURRENT DETECTION EQUIPMENT
The micro pipeline corrosion eddy current detector realizes the full coverage of the size, position and distribution of micro pipeline corrosion and high-precision intelligent detection by walking in the pipeline, which solves the technical problem that the corrosion of micro pipeline cannot be comprehensively detected. This system is especially suitable for corrosion detection of special pipelines such as small caliber, complex external space, and inability to carry out external inspection, and has a very wide application prospect in the corrosion detection of pipelines such as special ships, aircraft, and ships.
At present, it has four kinds of small-diameter pipeline corrosion eddy current detection equipment of 3.5’’, 4.2’’, 6.6’’ and 8.7’’, which has been successfully applied to the corrosion detection of various types of ship pipelines, making a comprehensive and accurate evaluation of the safety status of pipelines, and providing an important scientific basis for the safety and maintenance decisions of major equipment.
