On March 22nd, 2025, Cheng Haitao, Deputy Secretary-General of the Rolling Steel Branch of the Chinese Society for Metals and Consultant of the Steel Pipe Subcommittee of the National Steel Standardization Committee, along with Luo Liqiang, Chairman of Xinjiang Tiancheng Xiyu Steel Pipe Manufacturing Co., Ltd., and many members of the Iron and Steel Association, visited Pro-liner. They discussed the innovative achievements, standardized applications, and future development of pipeline repair technology, aiming to promote more innovative integrated development in urban construction.

At the symposium, Cheng Haitao, drawing on his over 40 years of experience in the steel pipe industry, emphasized the importance of standardization for improving industry quality and efficiency. As the main drafter of several national standards such as "Hot-rolled Seamless Square and Rectangular Steel Pipes for Structural Use" (GB/T 34201-2017), he stated: "Standardization is a bridge for the transformation of technological achievements and a core tool for enterprises to participate in international competition. Pro-liner practice shows that only by deeply integrating innovative technologies with standards can the overall upgrading of the industry be promoted."

The visit of the members of the Steel Pipe Subcommittee of the National Steel Standardization Committee and the leaders from Xinjiang Tiancheng Xiyu Steel Pipe Manufacturing Co., Ltd. has injected new impetus into the development of Pro-liner and opened up paths for technical standardization and cross-regional cooperation in the steel pipe industry. Under the dual background of the "dual carbon" goals and global competition, with innovation as the engine and standards as the link, China's trenchless industry is stepping into a new stage of high-quality development.
