Our technicians are all qualified to perform ultrasonic thickness testing on various materials. We utilize Olympus and other credible equipment to determine the thickness of materials.

Radiography Testing

We Specialize in Quick, Accurate, and High-Quality Radiography Testing.

Radiography Testing of conventional land-laid pipelines is the core business of National Inspection Services. We are proven experts in this field and are dedicated to the radiographic testing of welds to all industry standards including ASME, API, and AWS.

Radiographic Testing (RT) is an extremely popular non-destructive testing (NDT) inspection technique, thanks to its versatility in detecting a wide range of defects on multiple materials, and its ability to produce a permanent record of each inspection. Our staff of qualified, certified, professional radiographers operate within strict safety parameters.

We produce high-quality radiographs that allow us to utilize our interpretation skills honed through many years of experience to determine if an anomaly is an artifact, or if it can be accepted per code requirements.


Phased Array Ultrasonic Testing

Phased Array Ultrasonic Testing

Phased Array is the most advanced ultrasonic testing technique in the industry. Our technicians utilize the OmniScan MX2 to perform phased array ultrasonic testing of welds.

Phased array testing is a computerized process that provides a very detailed and accurate image of the weld, which allows technicians to determine the exact length, height, and depth of any defects that may be found. All welds are examined to industry standards including ASME, API, and AWS. We provide customers with quick, reliable results on-site, with all work being performed safely and efficiently.
