The global ultrasonic testing market was valued at USD 3.36 billion in 2024 and is projected to reach USD 5.12 billion by 2030, growing at a CAGR of 7.5% from 2025 to 2030. This growth is driven by stringent government regulations mandating Non-Destructive Testing (NDT), including Ultrasonic Testing (UT), across various industries.
Regulatory bodies like the U.S. Nuclear Regulatory Commission (NRC) require regular ultrasonic inspections of reactor components to detect cracks or weaknesses that could lead to catastrophic failures. For example, UT is used to inspect pressure vessels and piping systems in nuclear plants to prevent radioactive leaks. Similarly, in the oil and gas sector, regulations from agencies like the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) demand ultrasonic testing during pipeline construction and maintenance to ensure integrity and prevent leaks or explosions. These regulatory requirements significantly boost the demand for ultrasonic testing equipment and qualified personnel.
Technological advancements such as Phased Array Ultrasonic Testing (PAUT) and Time-of-Flight Diffraction (TOFD) are transforming the market by offering higher precision, faster inspection times, and improved defect detection. PAUT, for example, uses multiple ultrasonic probes to generate detailed images that enable precise flaw characterization. Organizations like the National Institute of Standards and Technology (NIST) are pivotal in developing standards and methodologies for these advanced UT techniques, ensuring their reliability and accuracy.
