![]() Note: The custom PA wedges listed above have been designed with specific application variables in mind. Nominal diameter of 0.5 in., resists temperatures up to 150 ☌. Squeeze Bottle (.06 liters), up to 200 ☏ (90 ☌).Ġ.3 m (1 ft) of protective sleeve to protect the probe and encoder cables. H-2 Couplant: Temperature range 0 ☏ (-18 ☌) to 750 ☏ (400 ☌) in many open environment applications when used per manufacturer's recommended procedure.*ī2 Couplant: Glycerin 2 oz. SA32C-ULT-N55S-IHC: High-temperature wedge for angle beam phased array probe A32, normal scan, 55-degree shear wave, from ULTEM to steel, with IHC option (irrigation, holes, and carbides). Includes 5 ft of protective sleeve (Q7750078). SA31C-ULT-N55S-IHC: High-temperature wedge for angle beam phased array probe A31, normal scan, 55-degree shear wave, from ULTEM to steel, with IHC option (irrigation, holes, and carbides). Part numbers for equipment used for high-temperature inspection. Glycerine was used to couple the probe to the wedge, and high-temperature couplant was used to couple the wedge to the component. The OmniScan MX2 flaw detector was used to perform a typical sector scan from 40° to 70° SW with a resolution of 1 degree. Lab tests were performed on components that were heated to 150 ☌. However, as heat dissipation is also dependent on the geometry of the wedge, proper care needs to be taken and users shouldĬonsult with an Olympus representative to validate their request.Īn Olympus probe mounted on a ULTEM wedge. Relatively easy to machine, other Olympus wedge series could be manufactured with ULTEM material. These wedges include mounting holes for Olympus’ Mini-Wheel encoder, enabling encoded inspection. Two wedge models were designed with this specific application in mind both wedges are currently available for purchase-SA31C-ULT-N55S-IHC and SA32C-ULT-N55S-IHC. This material features elevated thermal resistance, strength, and stiffness due to its close to 200 ☌ high glass transition temperature. The wedges are manufactured with an amorphous thermoplastic polyetherimide resin called ULTEM™. In order to characterize and validate the efficiency of these wedges, laboratory testing was performed using the OmniScan MX2 flaw detector configured to perform a sector scan from 40° to 70° SW, which is typical for a weld inspection with phased array probes. Olympus has developed a new wedge series that enables inspections on hot components up to 150 ☌. Ultrasonic signal attenuation and frequency shift must also be taken into account. The sound velocity in the wedge and components also varies with temperature, and this can affect focal law calculations and index point displacements, leading to positioning errors when locating indications. The probe’s cable also has to be protected from the hot component being inspected. Insulation, heat dissipation, and cooling are three important factors in wedge design to prevent excessive heat from reaching the probe elements. To be used safely, the probes should not exceed a temperature of 60 ☌. Our testing demonstrates that typical phased array probes completely fail if they reach 80 ☌. To help mitigate this problem, Olympus developed a new tool that enables manual phased array inspection at temperatures up to 150 ☌.Īs phased array probes heat up, the piezoelectric elements and their electrical connections can be damaged. Piezoelectric elements and internal connections in typical phased array probes are sensitive to heat and can be damaged by high temperatures. ![]() Performing ultrasonic phased array inspections on high-temperature parts and components poses certain challenges.
