Phased Array Ultrasonic Testing – PAUT

NDT Thai service Co., Ltd. offers Phase Array Ultrasonic Testing is used to detect deterioration of pipe components such as cracks and can be adapted for welding inspection. thickness measurement Phased ultrasonic corrosion and crack detection uses a multi-component probe that is individually triggered under electronic control. The PA probe contains an ultrasonic transducer. Each of the many smaller ones can vibrate independently and generate a focused beam of ultrasonography by excitation of individual components in a controlled manner. The beam of ultrasound can be electronically guided and scavenged. Like a searchlight through metal or inspected objects, this method generates two- and three-dimensional views that show the size and location of the cracks detected in the planar view through the object. Because we can control the angle and focus of the beam. This method is therefore very effective in terms of speed and crack detection as a non-destructive test.

Magnetic flux leakage (MFL)

Magnetic flux leakage is a corrosion test of the tank floor. Tank Floor Scanning is a qualitative method to detect soil corrosion in the bottom slab of above-ground storage tanks using magnetic flux leakage (MFL) technique. It uses a magnetic field to detect corrosion and pitting in carbon steel. The MFL uses a powerful magnet to attract the bottom of the steel drum. Magnetic leakage from corrosion defects or material loss is detected by the MFL 3D sensor. MFL can provide discrimination between top and bottom surface defects.
