PSA's inspection/condition assessment service package includes nondestructive testing of boilers, particularly near drum regions that are susceptible to accelerated metal wastage and corrosion. We have inspected hundreds of thousands of tubes using  OmniScan™ and AccuScan™, automated ultrasonic scanning systems designed to quickly and accurately assess the condition of generating tubes in the near drum region.

Our highly qualified field engineers have a thorough understanding of boiler operations, thus providing more than simple data collection. Comprehensive knowledge, with reliable results provided by OmniScan™ / AccuScan™ allows PSA to interpret significant amounts of data on-site.

By using ultrasonic technology and a two-axis scanner drive unit, tubes are reliably scanned for thinning areas. Interpretation is key to determining the cause of tube thinning, as well as how it will affect pressure part life. Multicolor tube scans provide instant visual recognition of problem areas.

 

For flexibility, scans can be viewed in A-, B-, or C-scan formats, as well as in a C-scan three-dimensional mode that provides the operator a wider range of tools to interpret irregularities. The compact scanner size allows access to tubes other systems can't reach, which may eliminate the need to remove welded baffles or brackets.
