Application of Nondestructive Testing in the Manufacture for Deep-water Well Control Equipments

Throughout the process of deep-water well control equipments manufacture, according to different profile and working condition of parts, ray inspect, ultrasonic inspect, magnetic particle inspect, liquid penetrant inspect, metal magnetic memory inspect and acoustic emission inspect are used to inspect the defects of the parts. Synthetic application method of NDE，the correct time of NDE，configuration methods of NDE fitting for different parts and part configuration are mastered, providing safety quality guarantee for deep-water well control equipments manufacture.
