China Supplier Seamless Square Pipe - Ductile iron pipe Made in China K9 C30 C40 En545 ISO2531 – Lu

Introduction

The essence of cast iron steel pipe is ductile iron pipe. Because Ductile iron pipe has the essence of iron and the performance of steel, it is called this way. The graphite in the ductile iron pipe is in the form of spheroids, and the size of the graphite is generally 6-7. In terms of quality, the spheroidization grade of the cast iron pipe is controlled to be 1-3, and the spheroidization rate is ≥80%, so the mechanical properties of the material itself have been better improved, and it has the essence of iron and the performance of steel. The annealed ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite and good mechanical properties, so it is also called cast iron pipe.
Features: It has the essence of iron, the performance of steel, excellent anti-corrosion performance, good ductility, easy installation,
