Tubing repair is an important measure to reduce the comprehensive cost of production in oil production plants to improve the quality of repairing tubing. It can ensure the quality of oil and water wells to prolong the inspection cycle, reduce the rework of operations and reduce operating costs.  

As an important process in the tubing repair test line, the flaw detection can accurately and effectively detect the defects in the manufacture and use of the inner and outer wall and the pipe body of the oil pipe to ensure the repair quality of the oil pipe.

Fundamental of MFL-7389 Tube Magnetic Flux Leakage Detector

When the detected tubing is saturated and magnetized, the magnetic field lines are distorted by the magnetic lines of force at the defect blocking defect, and a part of the magnetic lines leak out of the inner surface of the MFL tube rod to form a leakage magnetic field, and the electromagnetic detecting method for detecting the leakage magnetic field by the detecting element is detected.

MFL tube inspection.  

The leakage magnetic field picked up by the probe from the defect is amplified and converted into a digital signal, and then visually reflected by the flaw detector to the display to display the defect signal from the flaw detector, and directly determine the defect type and size of the detected tube rod.

¢73 and ¢89mm tubing eccentric wear and corrosion pits are detected, automatic detection, automatic alarm, automatic identification, automatic alarm.

MFL-7389 Tubing Magnetic Flux Leakage Detector Brief Introduction

Our company's new MFI tube magnetic flux leakage inspection machine has high sensitivity to very small defects. It can effectively detect defects such as corrosion pits, eccentric wear on the inner wall of the tubing, thinning of tubing wall, etc.

Moreover, the eddy current testing speed is fast and pollution-free, and the detection is fully automated. The computer display screen is used to display the detection curve, automatic alarm, marking (defect of steel pipe), grading of tubing (grade I, II and scrap).

As a non destructive testing equipment manufacturers, BKN have been committed to developing and manufacturing high-quality and high-performance NDT equipment to provide customers with the best quality service.
