Application on:
Ductile iron pipe is a pipe made of ductile iron commonly used
for potable water transmission and distribution. This type of
pipe is a direct development of earlier cast iron pipe, which it
has superseded. The ductile iron used to manufacture the pipe is
characterized by the spheroidal or nodular nature of the
graphite within the iron. Typically, the pipe is manufactured
using centrifugal casting in metal or resin lined moulds.
Protective internal linings and external coatings are often
applied to ductile iron pipes to inhibit corrosion: the standard
internal lining is cement mortar and standard external coatings
include bonded zinc, asphalt or water-based paint. In highly
corrosive environments loose polyethylene sleeving (LPS) to
encase the pipe may also be used. Life expectancy of unprotected
ductile iron pipes depends on the corrosiveness of soil present
and tends to be shorter where soil is highly corrosive. However,
a lifespan in excess of 100 years has been estimated for ductile
iron pipelines installed using "evolved laying practices",
including use of properly installed LPS (polyethylene
encasement). Studies of ductile iron pipe's environmental impact
have differing findings regarding emissions and energy consumed.
