The Sonic MicroCirc S1 PAUT Scanner – TS-MCS1-45

Low-Profile Single-Probe PAUT / UT Scanner for Small-Bore Pipe Weld Inspection

The The Sonic MicroCirc S1 PAUT Scanner – TS-MCS1-45 is a compact, low-profile single-probe scanner designed for small-bore pipe weld inspection, tube weld inspection, circumferential weld scanning, encoded PAUT inspection, and conventional UT encoded scanning applications.

The scanner is developed for inspection areas where pipe diameter is small, access is restricted, and standard weld scanners cannot be easily used. Its compact chain-link design allows the scanner to travel around small pipe and tube circumferences while maintaining stable probe and wedge positioning.

The TS-MCS1-45 is suitable for ferrous and non-ferrous pipe materials, including carbon steel, stainless steel, alloy steel, duplex stainless steel, and non-magnetic pipe applications.

Product Overview

The MicroCirc S1 PAUT Scanner is designed for single-probe encoded ultrasonic inspection of small-diameter pipes and tubes. The scanner guides the probe and wedge assembly around the pipe circumference and provides accurate scan-position feedback when supplied with an encoder.

Its low-profile construction makes it suitable for limited-access inspection areas such as pipe racks, tube banks, boiler tube arrangements, heat exchanger areas, tight plant locations, fabrication joints, and compact circumferential weld inspection applications.

The scanner can be configured for pipe and tube diameters from 21.4 mm to 114.3 mm, equivalent to 0.84 inch to 4.5 inch.

Working Principle

The TS-MCS1-45 MicroCirc S1 PAUT Scanner wraps around the pipe or tube using an adjustable link arrangement. During inspection, the scanner travels around the pipe circumference while holding the probe and wedge assembly in position.

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

This supports:

• Small-bore pipe weld inspection

• Circumferential weld mapping

• Accurate defect location

• Defect length measurement

• B-scan and C-scan generation

• Position-based ultrasonic data acquisition

• Repeatable inspection documentation

Technical Specifications

Available Models and Variants

Single-Probe Holder System

The TS-MCS1-45 is designed with a compact single-probe holder system. The probe holder maintains the probe and wedge position during circumferential movement and supports stable contact during encoded scanning.

Suitable for:

• Small-footprint PAUT probes

• Compact weld inspection wedges

• Single-probe PAUT weld inspection

• UT probe and wedge assemblies

• Small-bore pipe weld inspection

• Tube weld inspection

• Custom probe and wedge configurations

Low-Profile Small-Bore Design

The scanner is designed for applications where access is limited and scanner clearance is critical. The low-profile arrangement allows scanning around small pipes, tubes, and restricted weld locations where larger scanners may not be practical.

Recommended for:

• Pipe racks

• Boiler tube welds

• Heat exchanger tube welds

• Tube-to-tube weld inspection

• Small-bore process piping

• Restricted access plant locations

• Compact circumferential weld inspection

Quick-Change Link System

The scanner uses an adjustable quick-change link arrangement to fit different small-bore pipe and tube diameters. The link system allows the scanner to wrap around the pipe circumference and maintain controlled scanner movement during inspection.

Benefits:

• Fast diameter adjustment

• Suitable for multiple pipe sizes

• Stable circumferential movement

• Useful for small-bore pipe inspection

• Suitable for ferrous and non-ferrous pipe materials

Encoder and Position Tracking

The TS-MCS1-45 can be supplied with a spring-loaded encoder for scan-distance tracking. The encoder maintains contact with the scan surface and generates position signals during scanner movement.

Encoder advantages:

• Accurate scan-distance measurement

• Reliable circumferential position tracking

• Better defect location accuracy

• Improved defect length sizing

• Position-based PAUT / UT data recording

• Repeatable inspection documentation

Cable Management and Irrigation

The scanner can be supplied with cable management and irrigation arrangements for field inspection use. This helps organize probe cables, encoder cables, and couplant lines during circumferential scanning.

Cable and irrigation features:

• Probe cable routing support

• Encoder cable routing support

• Couplant / water line arrangement

• Protective cable sleeve option

• Cleaner scanner movement during inspection

• Reduced cable interference during pipe scanning
