Pipe ductile cast iron pipes in ductile iron casting, ductile iron pipe said. Ductile iron pipe diameter, wall thickness, crisp texture, low strength, low price, the water supply pipe is the economy, the normal life of up to 20 ~ 25 years.
优点：在中低压管网，球墨铸铁管具有运行安全可靠，破损率低，施工维修方便、快捷，防腐性能优异等。
Advantages: in low pressure pipe, ductile iron pipe has the advantages of safe operation, low failure rate, convenient maintenance, convenient construction, good anticorrosion performance etc..
缺点：球墨铸铁管的连接受人为因素如操作水平、责任心等影响较大，施工方面不如PE管便捷。
Disadvantages: ductile cast iron pipes connected by human factors such as the operation level of responsibility, influence, construction convenient than pe.

Ductile iron pipe for water supply is divided into T type and K type
T型球墨铸管接口就是用胶圈用来连接的，安装方便。
T type ductile iron pipe interface is used to connect the rubber ring, convenient installation.
K型球墨管接口是用法兰来连接的，除胶圈外，还需要螺母螺栓，安装稍微复杂。
K type ductile pipe interface is connected with the flange, except the apron, also need to install nuts and bolts, slightly more complicated.
T型球墨铸管接口的尺寸从DN40--1400
T type ductile iron pipe interface size from DN40--1400
K型球墨管接口的尺寸从DN100-2600
The size of the K type ball ink pipe interface is from DN100-2600
