Pipeline Potable Cement Mortar Lining Pipe Centrifugal Cast 5.7M /
6M Length
Cement Lined Ductile Iron Pipe overview:
Ductile cast iron is kind of alloy of iron, carbon and silicon, in
which graphite exists in the type of spherical, generally the size
of graphite is 6-7 class, and spheriodization grade of the pipe
should be controlled 1-3 class(spheroidization rate is not below
80%). Thus after spheroidization, ductile cast iron possesses the
nature of iron as well as the characteristic of steel. After
annealing, its microstructure contains ferrite and a little
pearlite possessing excellent mechanical properties.
For pipes centrifugally cast, the minimum wall thickness, emin,
shall not be less than 3,0 mm. The nominal wall thickness, enom, is
equal to the minimum wall thickness, emin, plus (1,3 + 0,001 DN).
For pipes not centrifugally cast, the minimum wall thickness, emin,
shall not be less than 4,7 mm. The nominal wall thickness, enom, is
equal to the minimum wall thickness, emin, plus (2,3 + 0,001 DN).
For centrifugally cast pipes, nominal pipe wall thicknesses for
preferred ductile iron pressure classes are given
in Table 14. For other pressure classes, as given in Annex C, the
user should confirm the availability with the manufacturer.

Usage:
Much of the production of ductile iron is in the form of ductile
cast iron pipe, used for water and sewer lines. Ductile cast iron
pipe is stronger and easier to tap, requires less support and
provides greater flow area compared with pipes made from other
materials like PVC, concrete, polyethylene or steel. Ductile Iron
Pipe is the most widely-used pipeline product in water supply and
water drain/sewage projects.
Our advantages:
There are lots of qualified managers and technicians, and a
well-trained team of after-sales service, which provides all
services of manufacture, package, transportation and installation.
We are looking forward to cooperating with friends from abroad and
home creating a brighter future.
