Product Details

Ductile iron pipe introduction

Ductile iron, also called spherical graphite iron, is characterized by the presence of graphite in the resultant castings. It differs from flake graphite in that, it has a higher tensile strength, a proof stress and elongation. These characteristics ensure the suitability of ductile iron pipes and fittings for a majority of pipeline applications.

Advantage

1.For potable water supply

2.High strength

3.Long lifespan

4.Good corrosion resistance

5.Easy installation
