Core offering

Guided Ultrasonics designs, manufactures, and sells proprietary guided wave non-destructive testing (NDT) hardware, software, and monitoring systems used to inspect pipes, pipelines, rails, and structural elements for corrosion, erosion, and wall loss. Its portfolio spans the Wavemaker G5 and G4mini screening instruments, QSR1/QSR Axial/QSR ALF circumferential scanning systems, interchangeable transducer rings (Compact, Inflatable, Solid HT/HD/LITE, Slinky, Claw, Subsea), the permanently installed gPIMS sensor family with cloud-based Monitoring Studio, the G-Scan rail inspection system, and WavePro analysis software. The offering is completed by GULT qualification/certification training courses and hardware services including rental, repair, calibration, and spares.

Product overview

Guided Ultrasonics offers a comprehensive portfolio of guided wave inspection, scanning, and monitoring solutions for pipeline and industrial asset integrity management. The product suite centers on two main instrument families: the Wavemaker G5 and G4mini for long-range screening, and the QSR family (QSR1, QSR Axial, QSR-ALF) for short-range circumferential scanning. Supporting these are interchangeable screening rings including Compact, Standard Inflatable, HD Inflatable, HT Inflatable, HD Solid, HT Solid, LITE Solid, Slinky, Claw Transducers, and Subsea Rings for various pipe sizes and environments. The gPIMS permanent monitoring system with sensors, HT sensors, and Field Control Unit provides continuous monitoring via the cloud-based Monitoring Studio. Analysis is performed through WavePro4 and WaveProQSR software. G-Scan addresses rail inspection needs. The portfolio is complemented by GUL i-Button access control, training courses (GULT certification scheme), and hardware support services including rental, repair, calibration, and spares.

Products and services

• Wavemaker G5 Full-capability guided wave screening instrument for rapid 100% volumetric inspection of extended pipeline lengths (up to 400m diagnostic range per direction) from a single test position, with 32 data channels, 10.1-inch touchscreen, procedure-based operation, integrated GPS, and hot-swappable batteries. Targeted at enterprise pipeline integrity teams.
• Wavemaker G4mini Compact, lightweight (4.4kg) guided wave inspection instrument with 16 data channels, automatic sensor recognition, and simple test setup for screening long pipeline sections with 100% volumetric coverage. Sold to pipeline inspection crews performing routine integrity work.
• WavePro4 Software Windows-based guided wave analysis software that interfaces with Wavemaker G4 and G4mini instruments for data collection, validation, analysis, and reporting, with DAC curves, A-Scan, C-Scan, and EFC processing capabilities.
• WaveProQSR Software Real-time configuration and data collection software for QSR instruments that validates and analyzes data for reporting, interfaces with QSR instruments via USB or Ethernet, and connects to GUL's cloud-based Machine Learning platform for automated analysis.
• QSR-ALF Adjustable Large-diameter Frame that supports guided wave scanning on large-diameter pipes (12 inches to flat), operates with the same sensor carts as QSR1 configuration using circumferential propagation with a robust, semi-automated design. Targeted at refineries and petrochemical plants with large-bore process piping.
• QSR1 Circumferential guided wave scanning device that uses Quantitative Short Range (QSR) technology to move axially along the pipe top sending guided waves around the circumference to generate a thickness profile and quantitative measure of remaining wall thickness, for pipe diameters 6 to 24 inches.
• QSR Axial Low-profile guided wave scanning device for tight spaces near pipe supports and in pipe racks, combining with the QSR1 electronics pod to send guided waves axially along the pipe while moving circumferentially, for nominal pipe sizes 4 to 48 inches.
• Compact Rings Lightweight screening rings with reduced axial width and radial clearance for rapid deployment, featuring easy-fit modules including EC-TRIO, EC-HD, and EC-30/42 transducer types covering pipe sizes 6 to 40 inches.
• Standard Inflatable Rings Pneumatic inflatable transducer rings that use pneumatic pressure to press transducer modules against the pipe wall for effective inspection of larger diameter pipes, covering pipe sizes 6 to 36 inches with interchangeable modules.
• HD Inflatable Rings High Definition inflatable rings with HD transducer modules providing higher sensitivity and resolution for pipe sizes 6 to 36 inches, featuring enhanced circumferential sensitivity with a screw-lock latch.
• HT Inflatable Rings High Temperature inflatable rings with EFC performance capable of testing pipes operating at up to 300°C, suitable for nominal pipe sizes 6 inches and above with pneumatic loading.
• HD Solid Rings High Definition solid rings utilizing a high frequency regime for higher sensitivity and resolution on pipes 3 to 6 inches diameter, with spring-loaded transducers and EFC performance.
• HT Solid Rings High Temperature solid rings milled from aluminum for screening pipes 2 to 8 inches diameter operating at up to 350°C (660°F), with spring-loaded transducers and ergonomic fastening handles.
• LITE Solid Rings Lightweight solid rings milled from plastic for screening pipes 2 to 6 inches diameter at temperatures up to 150°C, with 8 or 16 spring-loaded channels for bare, painted, and sleeved pipe applications.
• Slinky Ultra-low profile ring designed for pipes with very limited radial clearance requiring less than 25mm clearance, suitable for culverts and pipe racks covering API nominal pipe sizes 2 to 8 inches.
• Claw Transducers Compact transducer designed for efficient boiler tube inspection and small-diameter pipe inspection in restricted access areas, available in 2-row and 4-row models with spring-loaded grip for fast attachment.
• Subsea Rings Modular underwater guided wave inspection solution deployable by ROVs or divers for subsea applications including risers, caissons, flowlines, and splash-zone sections, with ROV deployed, diver deployed, and gMAT magnetic versions available.
• G-Scan Rapid rail inspection system deployed on tracks during normal operation, using multiple guided wave modes simultaneously to screen the entire rail cross-section in a single test for defects including corrosion in general rail, level crossings, rail welds, and tunnels.
• gPIMS Sensors Environmentally robust permanently installed sensor rings providing both local thickness monitoring and large-area guided wave monitoring for long-term pipe integrity, with ATEX/IECEx versions for hazardous areas, for pipe sizes 3 to 72 inches.
• gPIMS HT Sensors High temperature variant of gPIMS sensors designed for bonding onto pipes under insulation, with a process temperature range of -40°C to 200°C, intrinsically safe version available, for pipe sizes 2 to 48 inches.
• gPIMS Field Control Unit Autonomous data collection unit that collects and stores data from connected gPIMS sensors, available in USB, 4G wireless, and ATEX/IECEx certified EX versions, with solar charging capability.
• Monitoring Studio Cloud-based portal for viewing and analyzing gPIMS monitoring data, including wall thickness trends, area monitoring with better than 1% cross-section change sensitivity, automated corrosion rate calculation, and reports. Available in PayG, Basic, and Advanced subscription tiers.
• GULT Qualification and Certification Scheme In-house GULT qualification scheme with tiered Levels (1 P Pipe, 2 XB Road-Crossings and Buried Pipe, 2 SP Process Piping and Pipe Supports, 2 PM Pipe Monitoring, 1 QSR Scanning, and Level 1 & 2 Combined) that trains and certifies inspectors to operate GUL equipment, supported by a five-year certification validity and required i-Button access control.
