Features of Flange Pipes:

Ductile cast iron, also called ductile iron, spheroidal graphite iron, or nodular cast iron, is a type of cast iron invented in 1943. While most varieties of cast iron are brittle, ductile cast iron is much more flexible and elastic, due to its nodular graphite inclusions.

· Ductile Iron Pipe offers proven reliability and the quality.

· It is quick and easy installation.

· The ductile iron pipe has high pressure capability.

· Available in sizes DN80 – DN2000

· Both T Type (Push-on Joint) and K Type (Mechanical Joint) are available

Q:What is ductile iron pipe?: The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Execution standard GB/T13295-2003ISO2531/2003

Q:What is ductile iron?: Ductile iron, after being treated with either magnesium or cerium, undergoes an improvement in its mechanical properties. This particular type of cast iron earns the name "ductile" due to its higher degree of ductility in comparison to other cast iron varieties. Ductility pertains to a material's capacity to stretch or deform without breaking. This quality renders ductile iron particularly ideal for applications that demand both high strength and resistance to wear and tear, such as pipes, automotive components, and machinery parts. The inclusion of magnesium or cerium during the manufacturing process aids in the formation of graphite within the iron's structure, contributing to its distinctive properties. This graphite formation serves to enhance the iron's flexibility and reduce its brittleness, enabling it to absorb shock and vibrations without fracturing. As a whole, ductile iron presents a fine balance between the strength of cast iron and the flexibility of steel, thereby establishing itself as a versatile material well-suited for diverse industrial applications.

Q:Are ductile iron pipes suitable for water distribution networks?: Ductile iron pipes are a suitable choice for water distribution networks. They have been widely used in water distribution systems for many years, thanks to their numerous advantages. To begin with, ductile iron pipes possess excellent durability and a long lifespan. Their resistance to corrosion is crucial for water pipes since they are continuously exposed to various chemicals and substances in the water. This corrosion resistance ensures that the pipes maintain their structural integrity over time, reducing the frequency of repairs or replacements. Furthermore, ductile iron pipes have a high strength and can withstand high pressure, making them ideal for water distribution networks. They can handle heavy loads and resist external forces such as soil movement or traffic loads, guaranteeing the safety and reliability of the water supply. Moreover, ductile iron pipes exhibit excellent hydraulic properties. With their smooth internal surfaces, they minimize friction and pressure drop, enabling the efficient flow of water through the system. This aids in conserving energy and reducing pumping costs, making ductile iron pipes a cost-effective choice for water distribution networks. Additionally, ductile iron pipes are versatile and can be easily installed in various soil conditions. They can endure ground movement and settle without breaking, which is crucial for maintaining a stable water distribution system. In conclusion, ductile iron pipes are highly suitable for water distribution networks due to their durability, resistance to corrosion, high strength, excellent hydraulic properties, and versatility in installation. They offer a reliable and efficient solution for delivering safe and clean water to communities.

Q:Ductile iron pipe joint damage, water leakage, want to see the connection with other pipe fittings, how to operate?!: The ink tube is really not good. Oh, have you tried blocking it with cement or plugging it with putty?Just pick up PE haha

Q:Which is good for water polo cast iron pipe steel pipe?: Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;

Q:What is the difference between spheroidal graphite cast iron QT400-15 and QT400-15A? What does the A mean later?: The front is the material grade, and the back of the A should have special requirements.
