ductile-iron pipe

A pipe that is fabricated of a cast-iron alloy in which graphite replaces the carbon that is present in cast-iron; provides the same advantages as cast-iron pipe along with the added advantage of a higher external load-bearing capacity; not as brittle as cast-iron pipe (thus permitting rougher handling) but higher in cost.
