Non-destructive testing is performed on in-service and out-of-service equipment to identify potential failure mechanisms which could become a safety or reliability issue. A2Z NDT Inspection Services specializes in providing non-destructive testing services to the upstream, midstream and downstream oil and gas markets while also providing services to pulp and paper, power generation, structural fabrication and civil works. Our office has mobile radiography rigs available for short term and long term pipeline, plant construction and plant maintenance projects. In addition we offer a much more encompassing non-destructive testing offering in each of the regions we operate depending on the areas primary activity. You can rely on A2Z NDT Inspection Services to provide quality personnel with experience.

Magnetic Particle Testing (MT)


Used for finding surface/near surface defects in ferromagnetic material, (MT) is a versatile inspection method used for field and shop applications. works by magnetizing a ferromagnetic specimen using a magnet or special magnetizing equipment. If the specimen has discontinuity, the magnetic field flowing through the specimen is interrupted and leakage field occurs. Finely milled iron particles coated with a dye pigment are applied to the specimen. These are attracted to leakage fields and cluster to form an indication directly over the discontinuity. The indication is visually detected under proper lighting conditions. A2Z NDT Inspection Service has experienced technicians that can provide this service anywhere.

Liquid Penetrant Testing (PT)


Penetrant testing – Based on the properties of capillary action, or the phenomenon of a liquid rising or climbing when confined to a small opening due to surface wetting properties of the liquid, Penetrant testing is used for finding surface breaking discontinuities on relatively smooth, nonporous surfaces. A2Z NDT Inspection Service has experienced technicians that can provide this service anywhere.



Ultrasonic Testing (UT)


Traditional Ultrasonic inspection uses high frequency sound energy to conduct examinations and perform measurements. Considerable information may be gathered during ultrasonic testing such as the presence of discontinuities, material or coating thickness. The detection and location of discontinuities is enabled by the interpretation of ultrasonic wave reflections generated by a transducer. These waves are introduced into a material and travel in a straight line and at a constant speed until they encounter a surface. The surface interface causes some of the wave energy to be reflected and the rest of it to be transmitted. The amount of reflected vs. transmitted energy is detected and provides information on the size of the reflector, & therefore the discontinuity encountered.

Gamma Ray (RT) Radiography Testing


A2Z NDT Inspection Services X-Ray capabilities range from 4 MEV units utilized to radiograph extremely large and thick castings and forgings, to portable X-Ray cameras used for field weld applications and thin wall material inspection.



A2Z NDT provides a variety of visual inspection techniques to multiple industries. All NDT techniques are based on interpreting visual anomalies to determine test specimen soundness as detailed by the code or specification to which the test is performed.
