About SYI Ductile iron pipe - SYI Group :
- PRODUCT INTRODUCTION
Di pipe k7 -SYI Group
Centrifugally Cast Ductile 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.
Possessing high strength, good toughness as steel and better corrosion resistance than steel, the ductile iron pipe is the ideal substitute for gray cast iron pipe and common steel pipe. In addition, the DI pipes are produced with good straightness, even wall thickness, high dimension accuracy, smooth surface finishing and remarkable mechanical properties, plus with firmly sticking internal & external coating layer. Flexible Push-in joint and rubber gasket are used resulting in convenient installation of pipelines.
By combining amazing ductility and high tensile strength to the well established corrosion resistance qualities of ductile iron, this easily handled pipe can be readily tapped, drilled or welded. Ductile Iron Pipes offer unsurpassed benefits for applications in water supply, sewerage and gas mains by their reputation by actual performance!
- ASSURED PERFORMANCE:
- Proof tested: Every piece of Ductile Iron Pipe must be hydrostatically tested according to standard requirements before application of lining or coating.
- Long Life: In over 1000 locations in the world cast iron mains are still in service over 100 years.
- Design: ISO/EN/AWWA/AS specifications provide a high factor of safety based on rated pressure plus surge allowance without damage to the pipes.

- Design Flexibility: Pipes will safely function over a wide range of operating pressure, trench loads and installation conditions. Standard design includes a generous factor of safety to protect against unknowns.
- Easier Handling: Ductile Iron Pipes can be more easily manoeuvered under and around existing underground obstructions, thereby eliminating unnecessary changes in line or grade.

- ANGULAR DEFLECTION
When a small curve is required along the pipeline, adjustment can be easily made without using fittings owing to the flexible joints of the pipes. So, the pipeline with flexible joints can also wind with the change of the ground.
