Non-destructive testing (NDT) plays a crucial role in ensuring the integrity and safety of critical infrastructure, particularly in industries where pipelines are a lifeline. Among the various NDT techniques, Long Range Ultrasonic Testing (LRUT) has emerged as an efficient method for inspecting large volumes of material from a single test point. The development of LRUT technology has rapidly progressed since its inception in the 1990s, and one standout product that continues to redefine guided wave ultrasonic testing (GWUT) is Sonyks™ by Eddyfi Technologies.

Advantages of Guided Wave Ultrasonic Testing

Guided wave ultrasonic testing, particularly LRUT, provides several advantages over other NDT techniques. Unlike traditional ultrasonic thickness checks that are localized, LRUT examines 100% of the pipe wall volume from a single tool location. This capability is especially valuable in non-piggable pipelines or areas that are hard to reach, ensuring efficient inspection coverage. The technology has evolved over the years, incorporating longitudinal, torsional, and flexural guided wave types, along with phased array technology for focused ultrasound and improved defect analysis.

A case study showcasing the applicability of GWUT for short dead leg piping further highlights the instrument's versatility and effectiveness. “Dead leg inspections are crucial for ensuring the enduring reliability of pipeline systems, encompassing vital aspects such as safety, quality assurance, and environmental protection. Regulatory authorities, including the HSE, API, and EU-OSHA, outline explicit guidelines to uphold pipeline integrity. Compliance with these standards is not only a legal obligation but also a responsibility to safeguard the well-being of the workforce, the environment, and the public. Nevertheless, these dead-end sections have long posed a challenge for inspection.” Read more on Sonyks as the ideal solution here.
