On April 18, 2021, the three-day ITTC2021 ended successfully. The German Pavilion was set up for the first time in this exhibition, and the scale of the exhibition was further expanded. The 18,000 square meters exhibition space gathered 132 well-known companies, and all the products on site were sold out. 2411 professional visitors from 30 provinces, municipalities and autonomous regions across the country registered to visit the exhibition, and 133 registered to attend the seminar.

As the results of the epidemic prevention work are reflected, China's economy is on the road to recovery in the world. The exhibition site was crowded with people. Exhibitors and the audience had a lively conversation face to face. Although they were separated by masks, their hearts were tightly tied together. The business opportunities on the spot were unfolding everywhere, as if we were taking us into the spring day when the trenchless industry is full of vitality in 2021. The feedback from exhibitors and visitors reflects the growing demand for trenchless technology in the Chinese market. The active participation of foreign experts and reporters shows that international counterparts are paying attention to the continuous expansion of China's trenchless market. Driven by favorable domestic policies, the sustainable improvement of national sewage treatment plants, the quality and efficiency improvement of the pipeline network, and the repair of the pipeline network have been carried out in parallel. Facing the huge market of urban pipe network maintenance and repair, municipal enterprises or emerging enterprises have joined the trenchless industry one after another, and the number of exhibitors in the pipeline inspection and repair category has increased sharply. The title sponsored by Beijing Beipai Construction Co., Ltd. in the thematic sub-forums, 8 high-quality reports aroused enthusiastic responses.


ITTC is an important platform for getting acquainted with new customers, meeting old friends, delivering information on industry trends, and sharing future technologies. We are full of confidence in the future, and the global economy is gradually recovering. In 2022, the German Pavilion has clearly stated that it will bring more exhibitors. We will also arrange the exhibition halls according to the classification of trenchless technology to provide visitors with a better exhibition experience. In order to achieve this goal, we will continue to work hard.


Here, we sincerely invite relevant companies and professionals in the trenchless industry to participate in meetings and exhibitions. We look forward to discussing the development prospects of the trenchless industry and discussing business with you in Suzhou!
