Pressure Vessel Weld InspectionComposite InspectionWeld Inspection of Small-Diameter PipesCorrosion Mapping Inspection
Pressure Vessel Weld Inspection
A complete inspection of pressure vessel welds can be performed in a single scan using an OmniScan PA and manual scanner such as the HSMT series or a motorized scanner like the WeldROVER. By combining TOFD and PA in a single inspection pass, a significant reduction in inspection time can be achieved as compared with conventional raster scanning or radiography. Furthermore, inspection results are available immediately, enabling you to detect problems with welding equipment and fix them right away.
Composite Inspection
Parts made of laminate composite materials pose an inspection challenge due to their various shapes and thicknesses.
Olympus offers complete solutions for the inspection of carbon-fiber-reinforced polymer structures. These solutions are based on the OmniScan flaw detector, the GLIDER™ scanner, and dedicated probes and wedges designed for CFRP flat panel and radius inspection.
Weld Inspection of Small-Diameter Pipes
When coupled with the COBRA manual scanner, the OmniScan flaw detector is capable of inspecting pipes ranging from 0.84 in. OD to 4.5 in. OD. With its very slim design, this manual scanner is able to inspect pipes in areas with limited access. Adjacent obstructions such as piping, supports, and structures can be as close as 12 mm (0.5 in.).
Manual and Semiautomated
Corrosion Mapping

The OmniScan PA system with the HydroFORM scanner is designed to offer the best inspection solution for detecting wall-thickness reductions resulting from corrosion, abrasion, and erosion. In addition, this system detects mid-wall damage, such as hydrogen-induced blistering and manufacturing-induced delamination, and clearly differentiates such anomalies from loss-of-wall-thickness.
For this application, phased array ultrasound technology offers superior inspection speed, data point density, and detection.

The above mentioned software improvements are also incorporated into the OmniPC software allowing users to analyze data on a PC, while the OmniScan can be redeployed for other data acquisition jobs.

Dedicated Scanners and Accessories

HST-Lite TOFD Scanner

HST-Lite TOFD Scanner

The new HST-Lite scanner is the perfect choice for cost effective, one-channel TOFD inspections when signal quality is important. The combination of magnetic wheels and spring-loaded probe holders offer the stability required to perform high quality, one-line inspections. The scanner can be operated using only one hand, and will attach to ferromagnetic surfaces even when in an upsidedown position.

Stainless Steel TOFD Wedges

The HST-Lite, when bought as a kit, comes standard with the new stainless steel TOFD wedges. These wedges are considered a significant upgrade from the common Rexolite wedges, and a better option for most applications. They offer several advantages, including:

  • Better wear resistance without the hassle of carbide wear pin adjustments
  • Better coupling as carbide wear pins can lift the wedge from the surface
  • Shorter approach (by 3 mm) for better coverage of the top of the weld
  • More rugged for longer life

These wedges are compatible with the Olympus high-performance line of TOFD transducers.

TOFD Inspection of Small Pipes

Designed specifically for use with the wellestablished COBRA scanner, an additional line of TOFD wedges is available for low profile inspections. These wedges can be fitted with 3 mm element diameter ST1 probes to inspect pipes of 1 in. up to 4.5 in. These wedges are available in various longitudinal refracted angles and can be ordered for specific diameters, or from a kit covering the complete diameter range.
