Do You Know The Characteristics Of Ductile Iron Pipe?

Ductile Iron Pipe are seen in our daily life and production, and it has become an indispensable part of our life and production. The ductile iron pipe refers to a pipe which is cast by a centrifugal ductile iron machine after high-speed centrifugal casting using a cast iron water of No. 18 or higher, which is referred to as a bulb, a ductile iron pipe and a ductile cast pipe. It is mainly used for the transportation of tap water and is an ideal material for tap water pipes. We are also the Ductile Iron Pipe Fittings Exporter.

Ductile iron pipes are a type of cast iron pipe. The quality of the cast iron pipe is required to be controlled to 1-3 grade (spheroidization rate of 80%), so the mechanical properties of the material itself are better improved, with the nature of iron and the properties of steel. The annealed ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite, good mechanical properties, excellent anti-corrosion performance, good ductility, good sealing effect, easy installation, and is mainly used for water supply and gas transmission by municipal and industrial and mining enterprises , oil and so on. If you also need the High Quality Ductile Iron Pipe Fittings , please call us at any time.

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