Weld inspection for small diameter pipes

allow easy rotation around the pipe even when adjacent obstructions such as other pipes, supports and structures are as close as 12mm (0.5").

Olympus, a leader in non-destructive testing technologies and a pioneer in industrial phased array ultrasound, has introduced a comprehensive inspection solution for circumferential welds in pipes with a diameter as small as 21.3mm (0.84") OD. A key component of the solution is the new Cobra manual scanner specifically designed to inspect welds in small diameter pipes. The Cobra is used with the OmniScan ® MX phased array flaw detector with the 16:128 module and the OmniScan MXU software, to provide an economical and portable weld inspection solution. In addition to its capability of inspecting small diameter pipes, the Cobra one- axis scanner has a very low vertical profile, which allows it to be used in areas with minimal clearance.

designed to clamp onto carbon steel and stainless steel pipes of various diameters. It is characterised by its smooth-rolling encoded movement enabling precise data acquisition. The scanner can hold two low-profile phased array probes for a complete inspection of the weld in one pass. For pipe-to-component inspections, the scanner can be quickly configured to make one-sided inspections with only one probe. The phased array probes offer optimised elevation focusing,

The waterproof, rustproof and CE-compliant scanner ensures stable, constant and strong pressure, providing good UT signals and precise encoding around the full circumference of the pipe. Olympus NDT – USA meindert.anderson@olympusndt.com www.olympus-ims.com
