The 3rd Pro-liner Open Day came to a successful conclusion

Time:2025-10-17

From October 15th to 17th, 2025, to promote the exchange of advanced technologies and facilitate high-quality development of the industry, the themed event "Anchoring Intensive Development · Promoting Connotative Quality and Efficiency Improvement of Pipe Networks" and the 3rd Pro-liner Open Day, co-hosted by the Underground Pipeline Professional Committee of the Chinese Society for Geodesy, Photogrammetry and Cartography and Pro-liner, was grandly held in Anhui.

The event gathered industry leaders, experts, scholars and enterprise representatives from all over the country. They conducted in-depth discussions on key issues such as intensive development and connotative quality and efficiency improvement in the field of underground pipe networks, and jointly witnessed the important milestone of Pro-liner 10th anniversary.

In the technical exchange session, many industry experts shared the latest research results and practical cases. In their reports, industry experts systematically elaborated on the specific application of the concept of "connotative quality and efficiency improvement" in the construction of urban underground pipe networks, and how to improve the efficiency of existing pipe networks through technological innovation.

On the afternoon of the 16th, the participating guests visited our factory area. In the standardized production workshop, the guests observed in detail the intelligent production line of pipeline rehabilitation materials, gaining a more intuitive understanding of the company's production processes and quality control system.

In the curing demonstration area, our technical personnel demonstrated the application of potable water materials in the UV-CIPP process on site, including the port sealing technology after potable water pipeline rehabilitation. The guests had in-depth exchanges with on-site engineers on technical details and performance parameters, and highly praised our R&D strength in potable water technology.

In addition, we displayed the world's first DN2000*28mm ultra-large wall thickness UV-CIPP liner, which signifies our absolute strength in large wall thickness production.

It is worth mentioning that this year marks the 25th anniversary of Beijing Longkexing Technology Group Co., Ltd. and the 10th anniversary of Pro-liner. A special exhibition on the enterprise development history was set up in the factory area. Through various milestone events, it vividly showed the enterprise's struggle from its initial establishment to becoming an industry leader, demonstrating China's technological progress and industrial upgrading in the field of underground pipe network rehabilitation.

Pro-liner 10-year development history has witnessed the 10-year development of UV-CIPP in China's pipe rehabilitation. From introduction to localization breakthrough, from benchmarking to leading, every step has been solid and impactful.

On the evening of the 16th, we held a grand welcome dinner. Customer representatives, supplier representatives, industry experts and scholars of Pro-liner gathered together to celebrate this moment of special significance.

At the dinner, Liu Huizhong, Executive Deputy Secretary-General of the Underground Pipeline Professional Committee of the Chinese Society for Geodesy, Photogrammetry and Cartography, awarded a plaque to Pro-liner., designating it as the Anhui Chizhou Underground Pipe Network Trenchless Rehabilitation Popular Science Education Base.

On October 17th, a special training on urban drainage pipeline inspection, evaluation and trenchless rehabilitation was held, providing a platform for customers engaged in pipeline trenchless rehabilitation from all over the country to learn and communicate.

The 2-day event achieved fruitful results. The participating representatives agreed that promoting the connotative quality and efficiency improvement of pipe networks is an inevitable trend in the industry's development, which requires close cooperation among industry, academia, research and application sectors.

This Open Day event not only built a platform for industry exchanges, but also demonstrated China's innovative achievements in the field of underground pipe network rehabilitation. High-tech enterprises represented by Pro-liner are providing strong guarantees for the safe operation of urban underground infrastructure through continuous technological innovation.

Standing at the new starting point of its 10th anniversary, we will continue to uphold the corporate values of "Integrity, Innovation, Responsibility, and Excellence", work hand in hand with industry peers to jointly promote China's underground pipe network cause towards a safer, more efficient and more sustainable direction, and contribute more to urban construction and social and economic development.
