Our ductile iron pipes and fittings with internal protection are engineered to deliver reliable performance in both potable water and wastewater systems. Each product is internally lined with high-quality cement mortar, epoxy coating, or other food-grade materials, depending on application requirements, to prevent corrosion, ensure water purity, and extend service life.
As a leading manufacturer, Jingang LuoKaiWei follows strict international standards such as ISO 2531 and EN 545, ensuring that all pipes and fittings meet the safety, quality, and durability expectations of global infrastructure projects.
Internal protection plays a critical role in minimizing scaling, maintaining smooth flow, and resisting chemical or biological deposits. Whether you’re working on a municipal water supply system, an industrial installation, or a wastewater treatment plant, our internally protected ductile iron pipes and fittings provide a long-term, low-maintenance solution.
We offer a full range of fittings including socket spigot, flanged tees, elbows, reducers, and dismantling joints, all with protective linings to match your system’s specific needs.
