Guided Wave Ultrasonic Testing Tools for Long-Range Inspection

Non-intrusive GWUT systems offering high-efficiency pipe and structure monitoring across inaccessible areas

Overview

Guided Wave Ultrasonic Testing (GWUT) tools use low-frequency ultrasonic waves that travel along the length of pipes or other structures, enabling the inspection of long sections from a single location. This method is ideal for evaluating areas that are difficult to access or insulated, such as underground or elevated pipelines. By generating and analysing guided waves that reflect off defects like corrosion, pitting, or cracks, GWUT systems provide rapid, efficient, and cost-effective structural assessments.
This page provides a full breakdown of guided wave ultrasonic technology, highlighting its features, use cases, and industry relevance. Acoustic Testing Pro delivers high-performance GWUT tools across North America. As a growing B2B leader based in Atlanta, GA, we support infrastructure operators and industrial clients with advanced tools designed for reliability, safety, and long-term performance. Our goal is to make critical inspections easier, faster, and more accurate—no matter the environment.

Case Studies

United States

Pipeline Integrity Assessment – Natural Gas Utility, Oklahoma City

A utility company used GAO Tek’s guided wave system to inspect buried gas lines beneath road crossings. The system identified corrosion threats without excavation, allowing targeted repairs and preventing unnecessary disruption.

United States

Offshore Riser Inspection – Energy Operator, Galveston, TX

Acoustic Testing Pro deployed clamp-on GWUT tools to monitor offshore risers for wall thinning. The team delivered safe, efficient inspections in high-risk environments, reducing downtime by over 50%.

Canada

Pulp Mill Pipeline Survey – Industrial Facility, Prince George

A Canadian pulp mill used guided wave tools to scan long runs of steam and chemical pipelines under insulation. Results revealed early-stage corrosion, allowing for timely preventive maintenance with no insulation removal.
