Ductile pipe exactly how to choose quality on ductile iron pipes pipes of nodulizing grade control for 1 -
Level 3 (
Spheroidization rate of 80% or higher)
, and got better improvement on the mechanical properties of the material itself, has the nature of the iron, the performance of the steel.
After annealing of nodular cast iron
pipe, the microstructure of ferrite and a small amount of pearlite, better mechanical properties.
According to the performance of the ductile iron pipes, the technical personnel of our company give the Suggestions of how to choose.
So before it can be a good place in the development of the market, also only then to be able very good to understand the real needs of customers, can transform process.
