Epoxy Coated Ductile Iron Pipe
One-stop service
Epoxy-Coated Ductile Iron Pipe is composed of high-purity pig iron, nodulizing agents, and granulated blast furnace slag, externally coated with epoxy resin. Manufactured through high-temperature smelting, magnesium-based nodulization, and centrifugal casting processes, it is extensively applied in: Municipal infrastructure (water supply, drainage, gas transmission), Industrial piping systems, Bridge and road engineering drainage, Building water supply and firefighting systems.
features and advantages
High Strength & Toughness
Ductile iron pipes contain spheroidal graphite that disperses stress efficiently, enhancing strength and toughness. Compared to standard cast iron, their tensile strength increases by ≈40% and yield strength by ≈30%, enabling superior pressure and impact resistance.
Exceptional Corrosion Resistance
High-quality epoxy resin coating on both surfaces provides excellent chemical stability. This coating resists erosion from aggressive substances (including strong acids/alkalis) with a service life exceeding 50 years.
Improved Wear Resistance
The smooth internal surface minimizes fluid resistance and prevents sediment buildup, reducing wear. At identical flow rates, wear rates are ≈30% lower than standard cast iron pipes.
