What are the advantages and disadvantages of ductile Cast iron pipe?

advantage:

In the medium and low pressure pipe network (generally used below 6MPa), the ductile Cast iron pipe has the advantages of safe and reliable operation, low damage rate, convenient and fast construction and maintenance, and excellent anti-corrosion performance. The newly developed "Yandun" series pipeline can be suitable for non excavation construction and is widely used in pipeline construction across rivers, roads, and buildings. The "Sai Zinc" series pipeline uses a special zinc aluminum alloy external spraying process, which improves the corrosion resistance of the pipeline several times and is widely used in soil construction with strong corrosiveness.

Disadvantages:

Generally not used in high-pressure pipeline networks (above 6MPa). Due to the relative bulkiness of the pipe body, mechanical installation is necessary. After the pressure test, if there is water leakage, all pipelines must be excavated, lifted to a height that can fit into the clamps, and clamps installed to prevent water leakage.
