Advantages and disadvantages of ductile iron pipe

Advantage：

In medium and low pressure pipe network (generally used below 6Mpa), nodular cast iron pipe has the advantages of safe and reliable operation, low damage rate, convenient and fast construction and maintenance, excellent anti-corrosion performance, etc. The newly developed "Yandun" series pipeline can be applied to trenchless construction and is widely used in pipeline construction across rivers, roads and buildings“ "Saizn" series pipeline uses special zinc aluminum alloy external spraying process to improve the corrosion resistance of the pipeline several times, which is widely used in the construction of highly corrosive soil.

Disadvantages :

Generally, it is not used in high-pressure pipe network (above 6Mpa). As the pipe body is relatively heavy, machinery must be used during installation. In case of water leakage after pressure test, all pipes must be dug out, the pipes shall be lifted to a height that can be put into the clamp, and the clamp shall be installed to prevent water leakage.
