Non-destructive Testing

NON-DESTRUCTIVE TESTING

We always keep developing and incorporating techniques from various methods of nondestructive testing.

In our facilities we study and develop methods applications of acoustic emission, ultrasonic, and electromagnetic, including procedures development and training, run by our own professionals certified as level I and level III, granted by ASNT and SNQC systems.

 

Method – Electromagnetic

The electromagnetic method offers an extensive application through the detection and sizing of cracks, measurement of electrical conductivity up to pipes inspection installed in equipments, made of any electricityconductive material.

These traditional techniques of penetrant liquid and magnetic particle examination, mainly due to the possibility of inspection of painted surfaces, with little or no need for surface preparation, inspection regions of hard access and they have high productivity.

Method – Acoustic Emission

We have 27 years of experience with proven results.

We perform inspections by acoustical emission pressure vessels, industrial boilers, piping, steel structures, storage tanks, FRP equipment, during pressure tests monitoring in operation and continuous monitoring.

Method – Ultrasonic

Perform cold and hot thickness measurements with various types of  transducers from the miniaturized up to large diameter, operating at different frequencies and EMAT cylinder heads probes.

The thickness measurement of internal magnetite layer super heater tubes allows the estimation of the temperature of the skin that used in calculating multiple frequencies.

For detection and sizing of discontinuities using conventional techniques and more sophisticated as TOFD and Phased Array.

Among the applications of the immersion technique we can highlight inspection of heat exchangers tubes and industrial boiler by IRIS (Internal Rotary Inspection System).

A/B-Scan and C-Scan are applied for mapping residual creep life.

The measurement of small thickness of non ferromagnetic with various geometries also stands the measuring thickness of expansion joints.

For inspection of installed pipes in heat exchangers we use special internal probes and areas with loss of thickness.

Inspection techniques for remote field testing (RFT) and Magnetic Flux Leakage (MFL) have a wide range of applications, which stand out the inspection of tanks bottom mainly pipes and tubes installed in heat exchangers and industrial boilers.
