Abstract

Aimed at the practical requirement of tubular joints weld inspection of offshore platform structures of Shengli oil field, the ultrasonic phased array inspection arithmetic for offshore platform structures is proposed. The integrated design of ultrasonic phased array inspection imaging system for offshore platform structures is completed, the ultrasonic phased array inspection imaging system for offshore platform structure is integrated on the basis of the each module and the exploitation of subsystem, which is made up of computer, ultrasonic circuit system, scanning device and phased array transducer. The ultrasonic phased array inspection experiment of T shape tubular joint model is performed with the ultrasonic phased array inspection imaging system for offshore platform structures, the flaws characteristic could be exactly estimated and the flaws size could be measured. Experiment results indicate that the ultrasonic phased array inspection arithmetic for offshore platform structures is practical, the ultrasonic phased array inspection imaging system could inspect artificial defects in tubular joint model, such as slag inclusion, crack, gas porosity, etc., the whole development trend of flaws is factually imaging by the ultrasonic phased array inspection technology of offshore platform structures.
