Targeted Angle Beam Inspection: CT QUICK CHANGE WEDGE (1/4", 70°, 76mm AOD)

Enhance your ultrasonic testing (UT) capabilities for angle beam inspections on small to medium diameter pipes with the CT QUICK CHANGE WEDGE. This specialized wedge is precisely designed for use with 1/4" diameter transducers, featuring a steep 70° refracted angle, and a contour specifically matched for 76mm (approximately 3 inches) outer diameter (AOD) pipes. From CT, a provider of reliable NDT accessories, this wedge is an essential component for accurately detecting and sizing flaws in challenging cylindrical geometries.

Key Features and Benefits:

• Quick Change / Interchangeable Design: The "Quick Change" feature allows for rapid and easy swapping of transducers or wedges without the need for tools. This significantly boosts efficiency during inspections that require changes in probe size, angle, or adaptation to different surface contours.

• Optimal 1/4" Transducer Compatibility: Designed to perfectly couple with 1/4-inch diameter ultrasonic transducers. This common transducer size offers a good balance of beam spread and resolution, suitable for a wide range of flaw detection applications.

• Precision 70° Refracted Angle: This wedge produces a 70-degree refracted shear wave in common materials like steel. The 70° angle is particularly effective for:

  • Detecting near-surface flaws such as hydrogen-induced cracking or stress corrosion cracking.

  • Inspecting thin-walled components where a short sound path and steep angle are beneficial.

  • Examining weld cap and fusion line areas with high sensitivity.

• Contoured for 76mm AOD Surfaces: Features a precisely machined bottom surface contoured to match the curvature of 76mm Outer Diameter (OD) pipes or cylindrical components (corresponding to NPS 3" piping). This intimate contact ensures optimal acoustic coupling and consistent sound entry when inspecting pipes, maximizing signal strength and accuracy on challenging curvatures.

• Durable Construction: Manufactured from high-quality, wear-resistant material (e.g., acrylic or polyimide, depending on temperature requirements). This robust construction ensures long life and stable acoustic properties, even with repeated use in demanding industrial environments.

• Consistent Acoustic Coupling: The flat top surface ensures stable and repeatable coupling with the transducer, while the contoured bottom surface provides excellent contact with curved parts, minimizing signal loss due to poor coupling.

• Essential for Pipe & Weld Inspection: Angle beam wedges are critical for:

  • Small to Medium Diameter Pipe Inspection: Specifically designed for common industrial pipe sizes.

  • Weld Inspection: Especially effective for detecting defects near the surface or in thinner section welds.

  • Crack Detection: Locating fatigue cracks and other flaws that might be oriented perpendicular to the scanning surface.

Equip your ultrasonic testing toolkit with the CT QUICK CHANGE WEDGE (1/4", 70°, 76mm AOD) to enhance your ability to perform accurate, reliable, and efficient angle beam inspections on components with moderate curvatures and near-surface defect concerns.
