We can produce centrifugal ductile iron pipe from DN80 to DN1600 in accordance with GB/T113295， ISO2531，EN598 and EN545 standard. The connector type includes: T type, K type, N type and S type etc. The annual output is about 50000 tons.
The centrifugal ductile cast iron pipe is mainly used to transport water, oil and gas. The outstanding features of the nodular cast iron pipe are the following:
1 The centrifugal ductile iron pipe not only has the ductility, high strength and pressure-proof of steel but also has the corrosion resistance of grey cast iron.
2 The excellent mechanical property of the centrifugal nodular cast iron pipe(Elongation>=10, tensile strength>=420Mpa, pressure-proof >=4Mpa) accords with the requirements of high pressure-proof and resistance to deformation for the pipe used to transport water, gas and oil.
3 The ductile cast iron pipe has stable chemical properties. Plus anti-corrosion methods of zinc spraying and paint coasting, it has excellent anti-corrosion performance so that its service life is over 100 years.
4 The installation for centrifugal ductile iron pipe is convenient and quick and the construction cost is cheap.
5 High reliability. The centrifugal nodular cast iron pipe has high pressure-proof performance, good elongation as well as flexible joints. Medium leakage won’t come up even the axial direction deviates 3 or 5 degree. It has better quakeproof performance and base anti-sinking ability.
