What We Do

What is Non-Destructive Testing?

Non-destructive testing is analysis techniques used to evaluate the properties of a material, component or
system. NDT can save both money and time in product evaluation, troubleshooting and research because it
doesn’t permanently alter the article being inspected.

The terms Non-Destructive Examination (NDE), Non-Destructive Inspection (NDI), and Non-Destructive Evaluation (NDE) are also used to describe this technology.

NDT methods include ultrasonic, magnetic particle, liquid penetrant and radiographic.

Our Services

Our diverse global experience and technical expertise has given us the opportunity to work for large and small clients performing specialized inspections for:

  • Electro-Magnetic Wire Rope Testing
  • Ball/Rod Mill Gear Inspections by Phased Array and/or Magnetic Particle Inspection
  • Tank Inspections with Magnetic Crawler Performing Full Height Corrosion Surveys
  • Mobile and Stationary Equipment Inspections
  • Ultrasonic Piping Inspection of Steel and Plastic Pipe


Phased Array Ultrasonics is a powerful NDT technology that allows for quick and reliable assessment for embedded flaws that can’t be easily resolved with conventional testing.


Focus NDT has extensive experience in all welding environments. We provide weld procedure assistance and supervision of welder testing.

Corrosion Mapping

Corrosion and erosion can inflict significant damage and prove costly. Due to the risks involved, it’s important to recognize corrosion damage early to assist in operational maintenance.

Corrosion Mapping

  • Inspect large areas with mechanized scanners
  • Accurate information on amount and location of corrosion
  • Capable of detecting large and small diameter pitting, corrosion, erosion in piping, pressure vessels, tanks


Accuscan can reach scan speeds of up to 40”/second and can scan on diameters as small as 3” pipe and 24” long in length. The scanner and motor controller housing are sealed to prevent moisture damage. This scanning system is a slave system, which allows for easy access to the encoder feedback from the scanner and directing it into any UT system with encoder inputs with a single encoder whip that comes with the scanner.

Laser Mapper

The Laser Mapper makes laser corrosion mapping practical. It works on smooth, shiny and dull or rough surfaces without any special surface preparation. The Laser Mapper is capable of scanning at high resolutions at up to 30 inches per second.


  • Fast-Scan
  • Accurate to within +/0.002”(0.051mm)
  • Eliminates problems such as water loss


Automated Ultrasonic Testing (AUT)

Automated Ultrasonic Testing uses computer controlled mechanized scanners that move transducers over the surface of the material to collect optimized data on a predefined grid within the computerized interface.

Data can be obtained from a number of different transducers at one time. Real-time data enables the analysis of areas of interest immediately. AUT can utilize any ultrasonic transducer or technique in operation including conventional ultrasonic transducers, TOFD, phased array transducers or any combinations of these.

AUT inspection can be used on newly fabricated welds and for in-service inspection to detect and trend flaws.

  • All grades of carbon steel
  • Non-ferrous materials
  • High density polyethylene (HDPE) and other plastics
  • Certain layered materials, plastics and ceramics

  • Fabrication Shop Piping Examination as per B31.3 Code Case 181, B31.1 Code Case 179


  • Highly reproducible technique:
    • Computer controlled data acquisition
    • Data is stored for future comparison or audit
    • Data is gathered with weld positional information
    • 3D image presentation of all defects
  • Rapid large area inspection using automated scanners
  • Better ability than manual ultrasonic testing to distinguish flaw signals from geometric signals
  • Ability to trend flaws for growth by comparing to previous inspection results


  • Scan areas on test material must be accessible with no immediate obstructions to scan areas
  • Scan surface must be in a clean condition. Thin wall paints and other coatings are acceptable if no disbonding, flaking or other anomalies
    are present
  • Coarse-grained materials can present problems
  • Non-ferrous materials need to have alternative methods of securing the scanner to the material surface


Reports are prepared from standard laptops after the data has been transferred from the field unit. The data and reports are CD archived for future reference or inspection comparison. Reports are presented to the customer at the end of the shift before the crew has left the site. The formal
report is issued later after peer review. Reporting formats vary by customer request.


Electro-Magnetic (EM) Wire Rope Testing

EM Instruments can provide reliable data on the internal and external deterioration of ferromagnetic steel wire rope caused by corrosion, wear and
various changes of rope structure. This includes locked coil ropes and plastic coated ropes.

EM Instruments simultaneously indicate Local Fault (LF) patterns and measure Loss of Metallic Cross-sectional Area (LMA). Broken wires, lay distortion, inter-strand nicking, external wear or corrosion pitting causes LF. LMA is caused by corrosion, broken wires, external wear and
inter-strand nicking.

Combined LF and LMA information can be used to assist with:

  • Determining when a steel wire rope has reached the end of its safe working life and should be removed.
  • Estimating the Loss of Breaking Strength (LBS) of a steel wire rope.

Portable EM Instruments allow steel wire rope testing on site. The instruments consist of two inter-connected components:

  • A Console which displays the test results.
  • A Test Head through which the rope travels.

Preventative Safety

To ensure safety, it’s critical that steel wire rope be regularly non-destructively tested using an EM Instrument and augmented by a visual inspection of sections of the steel wire rope where significant deterioration is indicated. This two-fold information can be used to accurately determine the complete condition of the steel wire rope and track its rate of deterioration so that a valid assessment can be made for preventative measures to slow down the rate of deterioration or to determine replacement.

In many jurisdictions, government regulations require that steel wire ropes utilized in underground mining operations be regularly tested using EM instrumentation.


Raised Face (RF) & Ring Type Joint (RTJ) Flanges

Raised Face (RF) and Ring Type Joint (RTJ) Flanges are the most common seals used in piping systems depending upon the fluid, PT rating, construction material and connecting equipment. The RF Flange seal with a flat gasket is designed for installation between the raised faces of two mating flanges. The raised faces have a prescribed texture to increase their gripping and retaining force on the flat gasket. The RTJ Flanges are generally used in high pressure (Class 600 and higher rating) and/or high temperature services up to the 300°C range.
