Precision Phased Array Wedge: CT A15 Series with IH Option (60° Shear Wave, 2.375" AOD)

Optimize your angle beam phased array inspections on medium-small diameter cylindrical components with the CT Standard Wedge for A15 Series Phased Array Probes. Engineered for meticulous normal scanning, this wedge delivers a precise 60-degree refracted shear wave and is specifically contoured for 2.375-inch (approximately 2" NPS - Nominal Pipe Size) Axial Outside Diameter (AOD) pipes. Featuring the advanced IH option (with irrigation, mounting holes, and without carbides), this wedge ensures superior coupling, extended wear life, and enhanced operational efficiency.

Key Features and Benefits:

• Designed for A15 Phased Array Probes: This wedge is precisely manufactured to seamlessly integrate with CT's (and functionally equivalent) A15 series phased array probes, ensuring optimal mechanical fit and acoustic energy transfer.

• Optimal 60° Shear Wave Refraction: Delivers a nominal 60-degree refracted shear wave in steel, an ideal angle for:

  • Detecting and characterizing critical flaws such as cracks, lack of fusion, and volumetric defects.

  • Inspecting weld zones and heat-affected areas in a variety of materials.

  • Achieving excellent sensitivity to defects that are perpendicular to the inspection surface.

• Contoured for 2.375" AOD Pipes: The meticulously machined bottom surface of the wedge is specifically contoured to match the curvature of 2.375-inch Outer Diameter (OD) pipes (often corresponding to NPS 2" piping). This precise fit ensures:

  • Maximized Acoustic Coupling: Minimizes couplant loss and air gaps, leading to superior signal strength and reduced noise.

  • Consistent Beam Entry: Guarantees uniform sound propagation into the curved surface, critical for accurate defect sizing and positioning.

  • Efficient Circumferential Scanning: Ideal for inspecting circumferential welds or for detecting axial defects when scanning along the pipe's circumference.

• "Normal Scan" Configuration: Designed for conventional linear scanning along the length of the wedge's aperture, providing comprehensive coverage for a wide range of inspection scenarios.

• Advanced IH Option (Irrigation & Holes, No Carbides): This premium configuration significantly enhances the wedge's functionality and durability:

  • Integrated Irrigation Channels: Built-in channels allow for continuous couplant delivery, crucial for long inspection runs, automated scanning, and maintaining consistent acoustic coupling without manual reapplication.

  • Mounting Holes: Pre-drilled holes facilitate secure attachment to automated or semi-automated scanners and probe holders, ensuring stable and repeatable inspection setups.

  • Without Carbides: This indicates the wear surface is free of carbide inserts, which can be beneficial in applications where avoiding surface marring is critical, or where the base material is softer.

• Durable Construction: Crafted from high-quality, acoustically stable materials (typically Rexolite), known for their excellent wear resistance and consistent performance in harsh industrial environments.

The CT Standard Phased Array Wedge for A15 Probes with IH Option is an essential accessory for NDT professionals seeking precise, efficient, and robust ultrasonic inspection solutions for medium-small diameter pipes and cylindrical components.
