离心球墨铁管至今在******上己成为上水管的材料’并且正逐渐推广应用 燃气管道系统中，其原因在于离心球墨铸管具有钢管的强度与所需的伸长率， 而且耐腐蚀性能是钢管的两倍以上。柔性接口可以有效地起到防震效果。

我公司可以提供符合ISO2531/7186或EN545/598等标准要求,生产 DN80-DN2600的各规格范围的球墨铸铁管。

Centrifugal ductile iron pipes have become the material of water application pipes in the world, and are gradually being promoted in gas pipeline systems, because the centrifugal ductile iron pipes have the strength of steel pipes and the required elongation and their corrosion resistance is more than twice that of the steel pipes. Flexible joint can effectively prevent earthquake.

Our company can provide various specifications of ductile iron pipes of DN80- DN2600 in accordance with the standards of ISO2531/7186 or EN545/598.
