Special drill rod flaw detector for petroleum
設備為機電分開式，有電源控制、磁化系統、夾持部分、電動移動、氣動夾緊（或電動）、自動噴灑，可對鉆桿進行復合磁化，采用先進模塊化集成電路，具有深層裂紋的檢測功能，可進行電動移動尾架，氣動夾緊、自動噴液、磁化、轉動觀察（立式旋轉、縱向旋轉）、退磁等功能，全程微機控制。
The equipment is electromechanical, with power supply control, magnetization system, clamping part, electric movement, pneumatic clamping (or electric) and automatic spraying. It can compound magnetization of drill pipe. It adopts advanced modular integrated circuit and has the detection function of deep cracks. It can carry out electric movement of tail frame, pneumatic clamping, automatic liquid spraying, magnetization, rotation observation (vertical rotation, longitudinal rotation), demagnetization and other functions. It is controlled by microcomputer in the whole process.
