Ductile iron pipe is a kind of cast iron pipe. Quality requirements of the cast iron pipe ball grade control level 1-3 (nodularization rate "80%), so the material itself mechanical ductile iron pipe product library can be better improved, with the nature of iron, steel performance. Annealed ductile iron pipe, the microstructure of ferrite plus a small amount of pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, easy installation, mainly for municipal, industrial and mining enterprises to the water, gas , Oil and so on.
Ductile iron pipe advantage：
In the low pressure pipe network, ductile iron pipe with safe and reliable operation, low damage rate, construction and maintenance convenience, fast, excellent anti-corrosion performance.
Ductile iron pipe disadvantages：
In high-pressure pipe network, generally do not use, anti-pressure low. Due to the relatively bulky pipe, the installation must use mechanical. After the pressure test leaks, all pipes must be dug out, the pipe hoisted to be placed in the clamp height, install the clamp to prevent leakage.
