Specializing in Non-Destructive Testing.



Phased Array (PAUT) inspection of new welds in lieu of RT is becoming more and more popular. We can inspect your piping, boiler tubes, and pressure vessel welds and comply with ASME codes. PAUT can inspect these welds without clearing personnel from the shop / unit thus reducing personnel downtime. PAUT offers real-time results, and typically more sensitive to planar flaws like cracks and lack of Fusion. PAUT is also safer without the risk of exposing personnel to radiation.


Phased Array inspection is used to detect in service defects like surface cracking, localized pitting, general corrosion, HIC/SOHIC, and other volumetric flaws.

One recent advancement in PAUT is Total Focusing Method (TFM). TFM focuses the sound at all depths all the time, where traditional PAUT could only focus at one depth. The results are very accurate height sizing and defect positioning.  Often times, a simple 0 degree TFM scan will detect defects at any angle including vertical (parallel to sound beam). This makes signal interpretation very easy.

Our company has many years experience in HIC / SOHIC detection. This flaw is typically found with 0 degree scans, and can be difficult to determine the difference of an original flaw (lamination) or in service flaw (HIC / SOHIC).

TFM is an excellent tool to test for step cracking or linking of two laminar signals together.


Encoding data with AUT scanning as a permanent record is more expensive than traditional thickness testing but has many advantages.

- can be faster than UT for large scans due to not having to draw a grid.

- can provide thousands of readings for fitness for service calculations.

- can possibly provide enough information to eliminate opening equipment from turnarounds

- more reliable than traditional UT, less operator dependant, data can be audited, setup files can be recalled for future inspections which minimizes calibration error, data can be more easily compared to previous inspections.


A common concern with corrosion in plants are at the piping elbows.  Ultrasonics - this can be difficult to monitor as the thickness of elbow often varies and difficult to take readings at exact same location. Also susceptible to miss localized corrosion. RT can be done but only shows 2 walls (intradose and extradose typically). Also have the safety factor of Radiation.

Encoding 100% of elbows with Phased Array was previously not possible but now is with our new elbow scanner. We can now scan 100% of elbows in a short amount of time. Encoding elbows would drastically increase the probability of detection of small localized corrosion, offer repeatable results, and take the operator error out of the equation as client can see the entire elbow on the scan.

We can inspect flange faces for corrosion eliminating the need to open the flange on shutdowns. We can help establish corrosion rates by given a number percentage corrosion loss rather than a visual range. We can also inspect flange faces for cracking as in RTJ Flanges.  


Ultrasonics is used to examine thickness or measure corrosion in various components, and materials. Ultrasonics can examine an  extreme range of thickness to under 0.100" and not limited to thicker ranges.

Laminations are volumetric flaws in base metal from original fabrication. We can inspect for laminations on new plate as per applicable codes or inspect other areas prior to welding to ensure the weld is being made on solid material.  


Ultrasonics can be used to test bolts or studs in-situ without shutting down equipment / removing from flange. Thickness of bolts to be tested is practically unlimited.

Magnetic Particle or Liquid Penetrant Inspection can also be use to test bolts and studs if not in-situ.


Magnetic Particle and Liquid Penetrant Inspection are inexpensive options to examine materials for surface breaking flaws.

Ultrasonics and Phased Array Inspection can also be used to inspect surface defects and volumetric flaws.


Our company can provide CWB visual services.

We can provide in-service visual inspection such as pit gaging and boroscope.


Our company can offer Positive Material Identification verification of a variety of materials.  Ensure your welders are selecting the proper materials and welding electrodes.
