Ductile iron pipe is a new high quality pipes


Ductile iron pipe is manufactured by centrifugal casting process of a pipe, made of Nodular graphite cast iron. It is widely used in metallurgy, mining, water, oil and construction of urban public pipe works, transportation of water, gas, and other fluid media. It has the nature of iron, steel, high strength, good toughness, corrosion resistance, is a traditional cast iron pipes and the replacement of ordinary steel pipe products.   
In addition, the ductile iron pipe line is good, smooth surface and accurate, uniform wall thickness, size, good mechanical properties and adhesion of coating solid, flexible interface for t-type socket, rubber ring seal, easy to install. Ductile iron pipe as a new type of Double Socket Taper, adapted to the needs of modern construction of urban water supply, gas transmission project, wall is thin, good toughness, high strength, corrosion resistance, construction of convenient advantages, has the nature of iron and steel's performance.
By virtue of its superior mechanical properties, ductile iron pipes can be well applied to water, gas and so on. Foreign industrial developed countries phased out starting from 60 's of the previous century the ordinary grey Di Tee Fittings, universal adoption of ductile iron pipe, into the mid-70 complete the upgrading process of ductile iron pipes instead of the grey-iron pipes.
