Ductile Iron Pipe Erternal Paint with Epoxy
Ductile iron pipe is a type of cast-iron pipe made by adding magnesium to molten iron, which changes the graphite structure from flakes to spheroids. This transformation gives the pipe a much higher tensile strength, impact resistance, and flexibility compared to traditional gray cast iron pipes.
