Did you know Ductile Iron Pipe?

As a Ductile Iron Pipe Suppliers, share with you.

Ductile Iron Pipe refers to a pipe made of cast iron with a size of 18 or more, added with a spheroidizing agent, and then centrifugally cast by a centrifugal ductile iron machine. It is referred to as a ball tube, ductile iron tube, and ductile iron casting tube. It is mainly used for the transportation of tap water and is an ideal material for tap water pipelines.

Ductile Iron Pipe

The essence of the cast iron steel pipe is the ductile iron pipe, because the ductile iron pipe has the nature of iron and the performance of steel, so it is called this. The graphite in the ductile iron pipe exists in the form of spheroid, the general graphite size is 6-7 grade. The quality requires that the spheroidization level of the cast iron pipe is controlled to 1-3, and the spheroidization rate is ≥80%. Therefore, the mechanical properties of the material itself have been better improved, with the essence of iron and the performance of steel. After annealing, the ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite, which has good mechanical properties, so it is also called cast iron steel pipe.

Features: It has the essence of iron, steel performance, excellent anti-corrosion performance, good ductility, and easy installation. It is mainly used for water supply and gas transmission of municipal industrial and mining enterprises.

Ductile iron pipe is a type of cast iron pipe. The quality requires that the spheroidization level of the cast iron pipe is controlled to 1-3 (spheroidization rate>80%), so the material itself is mechanical

Can be better improved, with the essence of iron, steel performance. The annealed ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite. It has good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, easy installation, and is mainly used for water supply and gas transportation in municipal and industrial and mining enterprises. , Oil transportation, etc.

A certain amount of spherical graphite is distributed on the ferrite and pearlite matrix. According to the different nominal diameter and the requirements for elongation, the proportion of ferrite and pearlite in the matrix structure is different. The proportion of small diameter pearlite Generally not more than 20%, the general control of large diameter is about 25%.

Ductile iron pipe is a kind of cast iron, which is an alloy of iron, carbon and silicon. Graphite in nodular cast iron exists in the form of spheroid, generally the size of graphite is 6-7 grades, the quality requires that the spheroidization grade of the cast pipe is controlled to 1-3 grade (spheroidization rate ≥80%), so the material itself is mechanical The performance has been better improved, with the essence of iron, the performance of steel. The annealed ductile iron tube has a metallographic structure of ferrite plus a small amount of pearlite, and its mechanical properties are good.
