Many Regions Launch Renovation of Old Pipeline Networks, and the Application Proportion of New Anti-corrosion Pipe Fittings Keeps Rising
Apr 13,2026
In recent years, many regions across the country have accelerated the renewal of old urban water supply, gas and heating pipeline networks. Relevant projects have put forward higher requirements for the corrosion resistance, sealing performance and service life of pipes and fittings. In municipal pipeline network renovation projects, traditional cast iron pipe fittings and ordinary steel pipes are gradually replaced by plastic-coated composite pipe fittings, stainless steel pipe fittings and anti-corrosion alloy pipe fittings. Such new pipe fittings perform more stably in anti-aging, soil corrosion resistance and medium erosion resistance, which can effectively reduce the risk of pipeline network leakage and extend the maintenance cycle. With the progress of projects, the market demand for pipe fitting products with good anti-corrosion performance is growing steadily. Manufacturers are also continuously optimizing material formulas and processing technologies to improve the adaptability of products in complex underground environments, providing support for the safe and stable operation of urban pipeline networks.
