From raw water transportation and municipal water supply to industrial gas transmission and drainage, ductile iron pipes, with their superior mechanical properties, have become the ideal material for water supply pipelines.
So, what is ductile iron pipes made of possess both the “essence of iron” and the “performance of steel”? Today, we will delve into the composition of ductile iron pipes and explain why the DINSEN has become a trusted choice for customers in many countries.
Mechanical joint ductile iron pipe is an alloy of iron, carbon, and silicon. Its main components include carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), magnesium (Mg), and trace amounts of rare earth elements. The superiority of this material lies in the fact that by controlling the content of these elements, the morphology of graphite in cast iron is completely altered.
Through scientific proportioning, spheroidization, centrifugal casting pipes, and annealing heat treatment, the microstructure of ductile iron pipes consists of ferrite with a small amount of pearlite, resulting in extremely superior mechanical properties.
DINSEN strictly adheres to international standards to ensure that the chemical composition of every ductile iron pipe is within the optimal range. We have invested in advanced automated casting production lines, and through precise spheroidization and inoculation processes, we ensure that our pipes not only possess the essence of iron but also the performance of steel.
Choose DINSEN, choose a reliable commitment based on material science.
