The Sonic CircumTrack Q4 PAUT Scanner – TS-CTQ4-48

The Sonic CircumTrack Q4 PAUT Scanner – TS-CTQ4-48

Four-Probe PAUT / UT Scanner for Pipe Weld, Vessel Weld, Circumferential Weld, and Flat Surface Inspection

The The Sonic CircumTrack Q4 PAUT Scanner – TS-CTQ4-48 is an upgraded modular PAUT / UT scanner designed for four-probe ultrasonic inspection applications. It is suitable for pipe weld inspection, vessel circumferential weld inspection, pipeline girth weld inspection, tank shell weld inspection, flat surface weld inspection, corrosion mapping, and encoded ultrasonic scanning applications.

The scanner is designed to hold up to four probe holder assemblies, allowing wider inspection coverage, multi-probe scanning, higher productivity, and advanced inspection configurations. It can be adapted for different PAUT probes, UT probes, weld inspection wedges, A32 series probe configurations, and customized probe / wedge assemblies.

The TS-CTQ4-48 is suitable for carbon steel, stainless steel, alloy steel, duplex steel, non-magnetic pipes, vessels, tanks, and flat plate surfaces. It can be supplied with magnetic wheels for ferromagnetic materials and a chain / rope-link holding arrangement for stainless steel and non-magnetic pipe applications.

Product Overview

The CircumTrack Q4 PAUT Scanner is developed for inspection jobs where multiple probes are required to improve scan coverage, reduce inspection time, and support advanced weld inspection techniques.

Compared with a two-probe scanner, the Q4 version provides a stronger and wider scanner platform with provision for four independent probe holders. This allows the scanner to support multi-probe inspection strategies such as dual-side weld coverage, multi-angle PAUT inspection, combined PAUT / TOFD-support configurations, or customized inspection setups.

The scanner can be used for pipe circumferential scanning, vessel weld scanning, flat weld scanning, and large-diameter component inspection. It can be configured for pipe sizes from 3 inch up to 24 inch, with an extended configuration available up to 48 inch.

Working Principle

The TS-CTQ4-48 CircumTrack Q4 PAUT Scanner guides up to four ultrasonic probes or wedge assemblies along the required scan path. During pipe or vessel inspection, the scanner travels around the circumference of the component. During flat inspection, the scanner moves along the weld or inspection line.

When supplied with an encoder, the scanner converts movement into distance-based position signals. These signals are sent to the ultrasonic inspection system, allowing PAUT / UT data to be synchronized with the actual scanner movement.

The four-probe configuration allows multiple probes to scan simultaneously, improving inspection coverage and reducing the number of repeated passes required on the same weld.

This supports:

• Multi-probe weld inspection

• Wider scan coverage

• Accurate defect location measurement

• Defect length sizing

• Circumferential weld mapping

• Linear weld mapping

• B-scan and C-scan generation

• Position-based ultrasonic data acquisition

• Repeatable inspection documentation

Technical Specifications

Available Models and Variants

Four-Probe Holder System

The main advantage of the TS-CTQ4-48 is its four-probe holder architecture. The scanner can hold up to four probe and wedge assemblies, depending on the inspection technique and weld geometry.

Four-probe configuration is useful for:

• Multi-angle PAUT weld inspection

• Dual-side weld inspection coverage

• Wide weld zone coverage

• High-productivity encoded scanning

• PAUT and TOFD-support combined configurations

• Inspection of thicker welds and larger components

• Reducing repeated scan passes

• Customized advanced weld inspection setups

Each probe holder can be adjusted based on probe size, wedge size, probe offset, and required inspection position.

Magnetic Wheel Configuration

For carbon steel and ferromagnetic surfaces, the scanner can be supplied with magnetic wheels. The magnetic wheels help hold the scanner on the inspection surface and support stable movement during circumferential or linear scanning.

Recommended for:

• Carbon steel pipe weld inspection

• Pressure vessel weld inspection

• Tank shell weld inspection

• Structural steel weld inspection

• Horizontal, vertical, or inclined ferromagnetic surfaces

• Applications where magnetic holding improves scanner stability

Chain / Rope-Link Holding Configuration

For stainless steel, duplex stainless steel, aluminium, and other non-magnetic materials, magnetic wheels will function only as guide wheels and will not provide magnetic holding. For these applications, the TS-CTQ4-48 can be supplied with a chain / rope-link holding system.

The chain / rope-link arrangement wraps around the pipe circumference and supports the scanner movement around the pipe. This helps maintain scanner positioning and surface contact even on non-magnetic pipe materials.

Recommended for:

• Stainless steel pipe weld inspection

• Duplex stainless steel pipe inspection

• Non-magnetic pipe materials

• Alloy pipe weld inspection

• Large-diameter pipe inspection

• Applications where magnetic holding is not effective

Probe and Wedge Compatibility

The TS-CTQ4-48 scanner is designed to support multiple probe and wedge configurations. The four-probe holder system can be customized based on inspection method, probe size, wedge size, probe offset, and required scan coverage.

Suitable for:

• Standard weld inspection PAUT probes

• Single-probe PAUT inspection

• Dual-probe PAUT inspection

• Four-probe PAUT inspection

• UT probe and wedge assemblies

• TOFD-support configurations
