YUSHI Cart-Type B-Scan Ultrasonic Scanner - Precision Corrosion Detection for Pipes & Pressure Vessels
The YUSHI cart-type B-scan scanner is a purpose-built ultrasonic inspection tool engineered specifically for corrosion detection and inner-wall condition assessment on pipes, pressure vessels, storage tanks, and other critical industrial workpieces. As a dedicated non-destructive testing (NDT) solution for volumetric flaw imaging, this B-scan system delivers high-resolution subsurface imaging for corrosion mapping, wall thinning detection, and structural integrity evaluation across heavy industrial applications.
Standard Probe & Cross-Series Compatibility
This B-scan corrosion scanner comes standard with the GT560 ultrasonic probe, featuring a 5 MHz dual-element transducer design optimized for corrosion inspection and near-surface resolution. The system is fully compatible with all other probes within the same housing series, allowing users to swap transducers to match material type, wall thickness, and inspection requirements without replacing the scanner assembly.
Ergonomic Cart Design for Field & Lab Deployment
Built with an ergonomically contoured cart-style body, the scanner is designed for comfortable, fatigue-free manual operation during extended scanning sessions. Its rugged yet lightweight aluminum alloy construction balances structural durability with easy portability, making it suitable for both on-site field inspections and laboratory testing environments.
Water-Column Coupling for Stable, High-Resolution Imaging
The scanner utilizes water-column coupling method that eliminates the need for rigid acoustic wedges and ensures consistent, stable coupling throughout the entire scanning path. By maintaining uniform acoustic contact between the transducer and workpiece surface, this coupling technology delivers superior near-surface resolution and repeatable B-scan image quality.
Its straight-through flow design actively purges air bubbles from the water path, preventing signal interference and image artifacts while maintaining optimal probe-to-workpiece coupling. This design is particularly effective for continuous corrosion mapping scans where consistent signal quality is critical to accurate results.
Self-Adaptive Probe Holder for Irregular Surfaces
The integrated probe holder features a self-adaptive mechanism with internal springs that automatically adjust probe height to conform to curved or uneven workpiece surfaces — no manual tuning required during scanning. This self-adjusting feature effectively prevents missed defects caused by surface irregularities, enabling smooth, efficient scanning across pipes, vessels, and components with varying geometries.
Optional Travel Configurations for All Workpiece Conditions
To adapt to different inspection environments and workpiece materials, the bottom of the scanner can be fitted with optional magnetic wheels or rubber rollers. Both configurations ensure firm, consistent contact with the workpiece surface: magnetic wheels deliver secure adherence to ferromagnetic steel pipes and vessels, while rubber rollers provide smooth, scratch-free travel on non-ferrous and coated surfaces.
Simple Operation for Fast Corrosion Scanning
Operation is straightforward and intuitive: simply set the appropriate inspection parameters on the connected instrument, activate the water supply, and slide the scanner steadily across the workpiece surface to capture clear, detailed B-scan images in real time. The system enables rapid corrosion mapping and wall condition assessment without complex setup or calibration routines.
Additional NDT Scanning Solutions from YUSHI
YUSHI also offers a full range of complementary scanning accessories to expand your inspection capabilities, including draw-wire encoders and wheel-type scanners.
Draw-wire encoders are available with two mounting options: a magnetic base for secure attachment to ferromagnetic materials, and a suction-cup base for non-ferromagnetic smooth surfaces. The encoder provides accurate position reference during scanning, ensuring precise defect location and consistent scan mapping.
Wheel-type scanners integrate a single-element transducer that functions as a delay-line probe in water immersion environments. The scanner tire is manufactured from a low-acoustic-attenuation material with acoustic impedance matched to water, delivering excellent acoustic coupling. In practice, users only need to apply a thin water film to the workpiece surface to perform fast, convenient scanning.
Ideal for petrochemical, power generation, pipeline, and pressure vessel NDT applications, the YUSHI cart-type B-scan ultrasonic scanner delivers reliable, high-precision corrosion detection and imaging performance. Backed by flexible probe compatibility, adaptive surface tracking, and field-proven water coupling technology, it is a trusted solution for industrial non-destructive testing professionals.
