Product Overview

TheSonic India PAUT A32 Series COD Wedges are specially designed for A32 Probe Series phased array ultrasonic testing applications where inspection is performed on the outside diameter of curved components. The COD wedge configuration is suitable for circumferential outer-diameter inspection, where the wedge and probe arrangement are required to follow the curved OD profile of a pipe, vessel, shell, or cylindrical component.

In phased array ultrasonic testing, correct wedge selection is important for maintaining beam direction, surface contact, coupling stability, and repeatable inspection results. The COD wedge design helps provide better contact on OD curved surfaces during circumferential weld scanning and supports reliable ultrasonic transmission from the PAUT probe into the test component.

Manufactured from high-quality Rexolite material, the A32 Series COD Wedge supports efficient ultrasonic sound transmission, dimensional stability, and dependable performance in industrial NDT applications. The wedge is also supported with high-quality, high-standard damping material designed with a zero-tolerance approach toward unwanted ultrasonic sound acceptance. This damping support helps absorb, control, and divert unwanted ultrasonic energy, reducing unnecessary internal reflections, wedge noise, and signal disturbance during inspection.

Detailed Product Description

The PAUT A32 Series COD Wedge from TheSonic India is developed for accurate phased array ultrasonic weld inspection on circumferential outer-diameter curved surfaces. This wedge is selected when the inspection surface is located on the outside diameter of a cylindrical component and the scanning direction or wedge orientation follows the circumferential profile of the component.

Unlike a flat wedge, the COD wedge includes a curved contact design to support better surface matching on OD curved components. This helps improve wedge seating, probe stability, and coupling behavior during inspection. The COD configuration is especially useful for weld inspection applications where the probe must maintain consistent contact while scanning around the outside curved surface of a pipe, pressure vessel, shell, nozzle, or similar round component.

The Rexolite wedge body supports effective ultrasonic energy transfer from the phased array probe into the material. To improve signal quality, the wedge includes high-standard damping support designed to control unwanted ultrasonic sound paths. This helps reduce unwanted internal echo response and supports cleaner, more reliable PAUT inspection data.

The A32 Series COD Wedge is suitable for inspection companies, fabrication industries, pipeline and pressure vessel manufacturers, refinery maintenance teams, petrochemical plants, power plants, EPC contractors, and quality control departments requiring reliable PAUT accessories for OD curved surface weld inspection.

COD Wedge Application

The COD Wedge configuration is recommended for outer-diameter curved surfaces where the inspection requirement is circumferential. It is commonly used when the wedge must sit on the outside surface of a pipe, vessel, or cylindrical component while supporting inspection around the curved OD profile.

This configuration is different from AOD, AID, CID, and Flat wedge types. COD is selected when the inspection surface is on the outside diameter and the required wedge orientation or scanning application is related to the circumferential direction of the component.

Typical Applications

·       PAUT weld inspection on circumferential OD curved surfaces

·       Circumferential scanning of pipe welds and vessel welds

·       Outer-diameter inspection of cylindrical shells

·       Pressure vessel and process piping weld inspection

·       Pipeline fabrication and site weld inspection

·       Nozzle, shell, and cylindrical component inspection where COD geometry is required

·       Refinery, petrochemical, and power plant inspection applications

·       Boiler, header, and pressure component weld inspection

·       Manual phased array ultrasonic testing on OD curved surfaces

·       Scanner-assisted PAUT weld scanning on pipes and vessels

·       Industrial quality control, shutdown, and in-service inspection applications

Suitable Inspection Areas

The PAUT A32 Series COD Wedge is suitable for components where the inspection contact surface is on the outside diameter and the wedge requires circumferential OD curvature matching. It is commonly used for pipes, vessels, shells, cylindrical bodies, round components, and curved weld inspection zones.

For flat surfaces, the Flat Wedge configuration is recommended. For axial OD inspection, the AOD wedge configuration may be selected. For inner-diameter curved surface inspection, AID or CID wedge configurations may be required depending on inspection direction and component geometry.
