Technical Upgrade: Dual Innovation of Anti-corrosion & Intelligent Technology! Long-service Pipeline Systems Popularized, Ordinary Pipe Fittings Gradually Phased Out

2026 06/27

China’s water conservancy industry is experiencing rapid technical iteration in 2026, entering a high-quality development stage focused on long-term anti-corrosion performance, intelligent monitoring and operational safety. With the comprehensive implementation of urban-rural water supply integration, modernization renovation of large and medium-sized irrigation districts, reservoir efficiency improvement and urban underground pipe network renewal projects, engineering construction standards have been continuously upgraded, raising stricter requirements for valve body materials, anti-corrosion processes, pipeline adaptability, operational stability and later maintenance costs.
Traditional ordinary carbon steel pipes and simple anti-corrosion pipelines have long-standing defects including rusting, inner wall scaling, corrosive leakage and short service life. These problems not only cause water resource waste, but also trigger secondary water pollution, pipe bursting and frequent maintenance. To solve these industrial pain points, the Ministry of Water Resources has vigorously promoted advanced practical technologies, prioritizing the application of steel-lined PE composite anti-corrosion pipeline systems and integral cast steel valve equipment, upgrading national water pipe networks from basic usability to durability, high efficiency and long-term safety.
High-standard water conservancy projects currently adopt standardized complete-set configuration solutions. The main pipelines adopt steel substrates with food-grade PE inner lining. Gate valves are made of cast steel and equipped with bevel gear driving structures, featuring stable opening and closing, high pressure resistance and strong adaptability for large-diameter and long-distance water transmission. Supporting double flange expansion joints effectively buffer pipeline deformation caused by thermal expansion and foundation settlement. Standardized fittings including concentric reducers, four-way pipes and flanged short pipes ensure tight connection, high sealing performance and overall pipeline stability. Battery-powered electromagnetic flowmeters are installed for real-time intelligent flow monitoring, forming a complete water conservancy pipeline system integrating valves, pipe fittings, expansion compensation and intelligent monitoring.
This integrated system boasts strong adaptability, ultra-long service life and low maintenance requirements, widely applicable to reservoir hubs, water plant pump rooms, urban and municipal water supply, farmland irrigation, flood drainage and industrial water supply projects. Compared with traditional ordinary pipe fittings, the anti-corrosion system doubles the pipeline service life, greatly reduces later maintenance, replacement and water supply suspension costs, and fully meets the high-quality development goals of water conservancy projects for efficiency improvement, loss reduction and long-term stable operation.
Industry research shows that in 2026, an increasing number of municipal and water conservancy bidding projects explicitly require anti-corrosion integrated pipeline systems and intelligent monitoring equipment, while the market share of low-end ordinary pipe fittings continues to shrink. The industry is moving toward standardization, high quality and integrated supply, bringing huge development opportunities for professional original equipment manufacturers.
