Recently, the Science and Technology Extension Center of the Ministry of Water Resources organized experts to strictly screen the application technologies for the key promotion guidance catalog of advanced practical technologies in water conservancy, forming the 2025 Key Promotion Guidance Catalog of Advanced Practical Technologies in Water Conservancy. Tianjin Youfa Pipeline Technology Co., Ltd. was successfully selected based on its outstanding technological innovation, engineering practicality, economic benefits, and green environmental advantages of "Anti-corrosion steel pipes with flexible spigot and socket ends". This honor not only marks the authoritative recognition of the product by the national water conservancy regulatory department, but also signifies that Youfa Pipeline Technology's technical strength and product quality in the field of water conservancy engineering pipelines have reached the leading level in the industry. It will provide important product support for the improvement and long-term safe operation of China's water conservancy infrastructure construction, and promote the technological progress and industrial upgrading of the pipeline industry.

As a leading enterprise in the domestic water pipeline field, Youfa Pipeline Technology has been deeply involved in pipeline research and development and production for more than 20 years, always adhering to the core strategy of "technology innovation drives product upgrading". The Anti-corrosion steel pipes with flexible spigot and socket ends selected this time is the "flagship product" of Youfa Pipeline Technology innovation. Compared with traditional water transmission pipelines, this product forms a complete "six fold safety guarantee" and comprehensively solves engineering pain points:

Socket connections do not require professional welders, and can be operated by ordinary workers for 300 yuan/day, while welding requires professional welders for 800 yuan/day; By saving 400 yuan per port for joint filling materials, the construction period has been reduced from 20 days per kilometer to 5 days per kilometer, and the comprehensive cost of DN600 pipeline has been reduced from 250000 yuan per kilometer to 35000 yuan per kilometer. The cost reduction effect is directly visible.

Plug and play stability "abandons the welding process, and two teams in an Anhui project completed 8 kilometers of construction in 15 days, with an average daily installation of 500 meters; And the installation does not damage the anti-corrosion layer, eliminating the need for secondary repairs and adapting to the "rush to meet the schedule" requirements of water conservancy projects.

Flexible socket interfaces can transform pipelines from "easily breakable long beams" to "anti bending chain like components". The deflection angle of a single interface can reach 1° 30′ -3°30′.

The installation quality is guaranteed. Coated steel pipes with a working pressure below 2.5 MPa ensure safe operation for 50 years and are suitable for complex terrains such as climbing and crossing; Low water flow resistance, low head loss, and long-term energy savings.

It is extremely difficult to repair the inner wall after welding for steel pipes with a small diameter of 630 and below. The narrow space for manual operation makes it difficult to achieve uniform and complete coating of the inner wall anti-corrosion layer, which is prone to quality defects such as missed coating, uneven thickness, and poor curing, making the weld area the weakest link in anti-corrosion and prone to corrosion perforation in the future. Adopting a plug-in connection, there is no need for frequent repairs in the later stage, and the cost of repair and replacement can be reduced by more than 30%, with outstanding long-term economy.

No on-site hot work or use of hazardous materials such as acetylene is required, thereby eliminating fire hazards at the source; Easy to operate, reducing labor intensity for workers by over 50%, minimizing quality issues caused by fatigue work, and ensuring peace of mind throughout the construction process.

The inclusion of Youfa Pipeline Technology's socket steel pipe products in the key promotion catalog of the Ministry of Water Resources is not only an honor but also a responsibility. In the future, we will take this selection as an opportunity and use Tianjin Youfa Water Conservancy Pipeline Application Research Institute as a driving force to explore scenario based challenges and pain points on the front line of water conservancy engineering, further increase research and development investment in water conservancy specialized pipelines, and enable advanced technology to serve national water conservancy engineering construction faster and more accurately, contributing to the alleviation of water resource supply and demand contradictions and ensuring national water security.
