The national standard GB/T 41666.4 for plastic pipeline systems for non excavation repair of underground non pressure drainage networks - Part 4: In situ curing lining method - GB/T 41666.4 was proposed by the China Light Industry Federation, under the jurisdiction of the National Plastic Products Standardization Technical Committee (SAC/TC48), and jointly compiled by domestic research institutions, universities, design units, material manufacturers, and construction enterprises related to CIPP in situ curing lining method technology. After more than three years of joint efforts, the drafting team officially released this standard on March 15, 2024.
The main drafting units of this standard include 15 units, including Sun Yat sen University and Zhejiang Youwei New Materials Co., Ltd。Our General Manager Li Hongyang, as one of the main drafters, has incorporated years of material supply experience and data contributions into this standard. Since the establishment of this standard in 2022, our company has provided third-party testing and self testing data related to products over the years, laying a solid data foundation for the writing of the standard。
This participation in the formulation of national standards is beneficial for us,Greatly enhancing the professional image of the enterprise, maintaining the fortress of self-improvement, and shaping a well-known brand in the industry. For the industry, achieving standardization through the formulation, publication, and implementation of standards is the essence of standardization, and also plays a certain demonstration role in how enterprises can proceed with their work in the future。With the rise of era policies, the non excavation repair industry should be promoted to a new level by combining theory and practice。
