Product Introduction

Centrifugally Ductile Cast Iron Pipe is a kind of pipe made from spherical graphite cast iron by centrifugal spinning process. The pipes, which can convey many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility.

With its high strength, high elongation, corrosion resistance, resistance to shock, easy construction and many other fine features, ductile iron pipe is the best choice in today's world for conveying water and gas safely. Ductile iron, also called nodular iron or spheroidal graphite iron, is characterized by the presence of spheroidal graphite in the resultant castings.
Ductile iron pipes are available in a range of diameters from 80mm to 1600mm and are suitable for both potable water transmission and distribution (in accordance with BS EN 545) and sewerage (in accordance with BS EN 598).
Ductile iron pipes are simple to joint, can be laid in all weather conditions and often without the need for selected backfill. Its high safety factor and ability to accommodate ground movement make it the ideal pipeline material for a wide range of applications.

Ductile Iron Pipe

Ductile iron pipe

Ductile iron pipes are available in a range of diameters from 80mm to 1600mm and are suitable for both potable water transmission and distribution (in accordance with BS EN 545) and sewerage (in accordance with BS EN 598).
Ductile iron pipes are simple to joint, can be laid in all weather conditions and often without the need for selected backfill. Its high safety factor and ability to accommodate ground movement make it the ideal pipeline material for a wide range of applications.

Product details

1.The performance of internal pressure resistance:

Centrifugal ductile iron has the essence of iron and the performance of steel, so the ductile iron pipes have excellent security performance than pipes made from other materials. The designed working pressure is much higher than that of pipes made from other materials, the safty factor is pretty high, and the possible burst pressure is three times of the working pressure.

2.The performance of outer pressure resistance:

The high pressure resistance can avoid the requirement of the pipe bed and protective cover, making the pipes laying rellable and economic.

3.Inner anti-corrosion layer:

The inner layer of ductile iron pipes are centrifugally sprayed with cement mortar. Cement lining complies with the international standard ISO4179, ensuring the mortar strong and smooth. The motor coating will not fall off or foul, and its thickness is even ensuring the drinking water transferred by the pipes get good protection.

4.Protective coating:

The zinc spraying of ductile iron pipes could protect the pipes proactively through the electrochemical effect of zinc and iron. With the high chiorinated resin paint, the pipes will get enhanced anti-corrosion protection. The surface zinc spraying of each pipe is not less than 130g/m², amd cpmplies with ISO8179 standard. We can also increase the zinc spraying thickness or spray zinc & aluminum alloy layer according to the customers' demand.
