On April 26, 2024, the 27th China International Non Excavation Technology Symposium and Exhibition, which lasted for three days, came to a successful conclusion. The exhibition covers an area of 20000 square meters, and the organizing committee has selected more than 120 companies in the industry to showcase their latest products and technologies on site. Among them, 24 companies participated in the exhibition for the first time, accounting for 20% of the total exhibitors. 95% of the participating companies brought dozens of physical products for display, and all bare spaces were specially decorated. All exhibits were sold out. 3718 professional visitors from 19 countries and regions, 32 provinces, municipalities, and special administrative regions across the country registered to visit the exhibition. A total of 8080 people attended the three-day conference, and 172 people registered to participate in the seminar.


The China International Non excavation Technology Symposium and Exhibition is presenting the vibrant vitality and development potential of China's non excavation industry with an unexpected scale and a wealth of cutting-edge technologies, and is on the path to recovery as the Chinese economy takes the lead globally. The feedback from exhibitors and visitors reflects the growing demand for non excavation technology in China's national economic development. The active participation of foreign experts and speakers demonstrates the international peers' attention to the continuous expansion of China's non excavation market. Driven by favorable domestic policies such as the "Action Plan for Promoting Large scale Equipment Renewal and Consumer Goods Trade in" issued by the State Council, the sustainability improvement of non excavation related industries is being carried out in parallel with the improvement of pipeline quality and efficiency, as well as pipeline repair.

ITTC is an important platform for meeting new customers, old friends, disseminating industry trend information, and sharing future technologies. We are full of confidence in the future, and the global economy is gradually recovering. In 2025, we will continue to arrange exhibition halls according to the classification of non excavation technology, providing visitors with a better viewing experience. To achieve this goal, we will continue to work hard.

We sincerely invite all relevant units and professionals in the non excavation industry to attend the conference and visit the exhibition. We look forward to discussing the development prospects and business negotiations of the non excavation industry with you in Suzhou!
