Product Description

T type Joint Ductile Cast Iron Pipe (Push-on) 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 T-type Joint Ductile Iron pipes are from DN80mm to DN1800.  
T-type Joint Ductile Iron Pipes are layed in the way of flexible spigot and socket 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
