Core Viewpoint - The ultrasonic non-destructive testing (NDT) industry in China has developed rapidly, covering various industrial sectors, with a projected market size of 5.772 billion yuan in 2024, reflecting a year-on-year growth of 6.81% [1][17]. Overview - Non-destructive testing refers to methods that assess the properties and integrity of materials without causing damage, utilizing physical or chemical techniques to detect internal and surface defects [1]. - The main non-destructive testing methods include ultrasonic testing (UT), radiographic testing (RT), magnetic particle testing (MT), penetrant testing (PT), and eddy current testing (ET) [3]. Market Policy - Recent policies in China emphasize product quality and safety, mandating non-destructive testing across various industries to ensure compliance with standards [8][10]. - A series of regulations and action plans have been introduced to promote high-quality development in manufacturing and enhance the capabilities of inspection and testing services [8][10]. Industry Chain - The ultrasonic NDT industry comprises equipment manufacturers and service providers, with upstream suppliers including raw materials and components, and downstream markets spanning various sectors such as special equipment, rail transportation, and aerospace [11][13]. Market Demand - The special equipment sector represents the largest demand for non-destructive testing, accounting for approximately 30% of the market, followed by rail transportation at around 25% [13]. - The growth in infrastructure and manufacturing automation in the Asia-Pacific region, particularly in China, India, Japan, and South Korea, is driving market expansion [15]. Competitive Landscape - The ultrasonic NDT equipment market has high entry barriers, resulting in fewer participants and relatively mild competition, with key players including Shantou Ultrasonic Instrument Research Institute and Guangzhou Duopule Electronic Technology [19][22]. - The service market is more fragmented, with numerous small players, while larger institutions like China National Inspection Testing Group and Huace Testing hold significant market recognition [19][23]. Development Trends - The industry is expected to see increased demand from advanced manufacturing sectors such as electric vehicles and electronics, with ultrasonic testing technology expanding into non-metal and composite materials [26]. - There is a trend towards domestic substitution of high-end ultrasonic NDT equipment, driven by advancements in local research and development and government policies promoting self-sufficiency [26].
