Abstract:
     The said method and apparatus are mainly used in petrochemical industry and it replaces available manual detection for the inner wall quality of steel pipe after rust removal. Without affecting the integrity of steel pipe to be detected, a special optoelectromechanical apparatus enters the interior of steel pipe to be detected, collects corrosion pattern data from several points, and transmits the electric signal of collected data into computer processing system, where detection results are obtained. Detection with the present invention is low-costed, efficient, accuracy, reliable and without randomness.
