Product Description

Double Flanged Ductile Cast Iron Pipe  is the first choice of pipe for the municipal water supply project
with advantages of convenient installation, good seismic performance and corrosion resistance.
The range of sizes of our Ductile Iron pipes are from DN80mm to DN1800.  
Double Flanged Ductile Iron Pipes are layed in the way of mechanical flanged joint in the project site. 
 

Advantages of Ductile Iron Pipe 

* Ductile Iron pipe have better Mechanical Properties .

( Note:  Microstructure comparision between Ductile Iron Pipe, Steel Pipe and Grey Iron Pipe )

* Ductile Iron Pipe have better mechanical propeties 

* Ductile Iron Pipe have Higher Corrosion Resistance
