NDT in Chattanooga, TN

Since our founding in 1967, Applied Technical Services (ATS) has become one of the leading NDT companies in North America. Our Chattanooga, TN branch office specializes in Non-destructive Testing in Pulp and Paper, Petrochemical Plants, Construction Sites and Refineries.

Boiler Inspection Services

Fast, cost effective boiler surveys are performed by highly trained, experienced personnel using state of the art ultrasonic data loggers. Liquid penetrant inspection of composite tube material is performed to identify damaged areas, while non-ferrous coating surveys determine the overall thickness of the composite material. On-site computerized reporting is provided to give you quick, accurate results. Data analysis, trending and forecasting is also available. On-site services include radiography, magnetic particle, copper sulfate and visual examinations. Additionally, we can offer Digital Radiography services which eliminate typical “shoot windows” and allow all contractors to remain working while radiography ensues. This provides “near” instant results, greater productivity and greatly reduced outage time.

Paper Machine Inspections

ATS uses fully automated thickness crawlers capable of on-line velocity adjustments to compensate for changes in acoustical properties inherent in the casting process. This allows for an accurate thickness scan across the full length of a dryer can.

Internal visual examination of paper machine dryers is one of the most efficient and effective methods of inspection. During a visual inspection, the condition of internal components along with areas of shell thinning and grooving can be determined.

Magnetic particle inspection of the heads and journals of paper machine dryers, along with ultrasonic soundness inspection of the bolts is performed to find minor defects before they become major problems.

Construction Services

Our Tennessee office has inspectors trained and certified to perform the following types of visual weld inspections:

  • Certified Welding Inspector (C.W.I.) per AWS QC1-96
  • Stud Inspection per AWS D1.1 / AISC
  • Decking Inspection per AWS D1.3
  • Bolt Torque Inspection per AISC

Digital Radiography Services

Among the newest services provided to various industries, Digital Radiography eliminates typical film and the associated handling and storage needs of film. No on-site chemicals are required, the restricted entry zone is virtually eliminated in many cases, the results are available in minutes rather than hours and the results can be viewed on any standard computer and e-mailed anywhere for additional opinions of resulting weld conditions. Meeting all current codes, this methodology provides enhanced results in a faster, easy to handle format and can be conducted with a number of radiographic and X-ray isotopes to meet individual needs.
