The advantages are in the middle and low pressure pipe network (commonly used under 6MPa), the ductile iron pipe is safe and reliable while the damage rate is low. And the construction maintenance is convenient, quick. The anti-corrosion performance is excellent. The newly developed "rock shield" series can be applied to non-excavation construction and is widely used in pipeline construction of crossing, crossing and crossing buildings. Zn "series pipeline is used for special zinc alloy coating process, several times increase the corrosion resistance of the pipeline, widely used in the corrosive soil construction.
We provide good quality of ductile iron pipe, more information pls click here.
