離心球墨鐵管至今在******上己成為上水管的材料’并且正逐漸推廣應用 燃氣管道系統(tǒng)中，其原因在于離心球墨鑄管具有鋼管的強度與所需的伸長率， 而且耐腐蝕性能是鋼管的兩倍以上。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等標準要求,生產 DN80-DN2600的各規(guī)格范圍的球墨鑄鐵管。

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.
