Outage Services In the highly specialized and demanding environment of the pulp and paper and chemical industries, ATS leads the way with unsurpassed quality and service.

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 reporting is provided to give you quick, accurate results. Data analysis and trending is also available.

Near Drum Inspections

ATS offers the latest technology in Ultrasonic inspection of Boiler Tubes At or Near the Drum intersection. Our near drum inspection system will provide a c-scan of the tube thickness from approximately 3" outside the drum to as much as 1" inside the drum.

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.

Tanks, Pressure Vessels and Piping Systems

Through the use of automated ultrasonic thickness crawlers, continuous thickness scans can be performed on the shell of carbon steel tanks and vessels, as well as piping systems. This inspection data is presented in a graphical format that can include minimum wall thickness calculations in accordance with a variety of standards such as API-653. ATS employs an experienced staff of API -653, API-510, and API-570 certified inspectors.
