In 2026, with the continuous expansion of global cross-border municipal water conservancy projects and industrial pipeline supporting projects, the market demand for customized ductile iron pipe products is showing a rapid upward trend, and standardized ordinary pipe products can no longer fully meet the refined construction needs of high-end overseas engineering projects. Among them, 6-meter fixed-length customized ductile iron pipes and supporting customized fittings have become the most popular procurement products in international engineering bidding projects, bringing new market growth points for professional DI pipe manufacturers.
In the past, most overseas small and medium-sized projects adopted random-length ductile iron pipes, which required on-site cutting, polishing and secondary anti-corrosion treatment during construction, resulting in low construction efficiency, increased on-site waste, and hidden dangers of secondary corrosion at cutting sections. In contrast, factory prefabricated 6-meter fixed-length customized pipes have fixed specifications, no on-site processing required, clean and flat pipe ends, and complete anti-corrosion layers, which can greatly improve pipeline installation efficiency and reduce project construction costs and quality risks.
Industry survey data shows that more than 65% of global municipal pipeline bidding projects in 2026 have clearly listed fixed-length customized pipes and non-standard pressure-grade pipe fittings as preferred procurement materials. Overseas engineering contractors are more inclined to cooperate with Chinese professional manufacturers with independent customization capabilities, stable MOQ rules and standardized FOB quotation systems. Our factory's 10-piece MOQ for customized 6m DI pipes breaks the high-threshold customization limit of the traditional industry, enabling medium and large-scale overseas projects to obtain high-quality customized pipeline supporting services at lower procurement costs.
Insiders pointed out that the future ductile iron pipe industry will shift from simple standardized product sales to customized engineering solution services. Manufacturers with integrated capabilities of independent R&D, customized production, strict quality control and flexible trade terms will occupy the core market share. Supported by automated production lines and mature FOB export trade experience, Chinese DI pipe manufacturers will further expand their advantages in global engineering procurement and become the core supply base for customized water supply and drainage pipeline products worldwide.
