6M Cement Lined Ductile Iron Pipe Zinc Spraying With ISO2531 Standard
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.
