可锻铸铁管道

Ductile cast iron pipe not only retains all of cast iron pipes attractive qualities, such as machinability and corrosion resistance, but also provides additional strength, toughness, and ductility. It is lighter, stronger, more durable and more cost effective than cast iron pipes. It is reliable for transporting raw and potable water, sewage, slurries, and process chemicals.
