Product Description

The ductile cast iron pipe, often recognized as ductile iron pipe or DI pipe, is an advanced piping solution prominently used in water and wastewater applications. Crafted from high-quality cast iron enhanced with graphite nodules, this pipe offers superior flexibility, strength, and durability, setting it apart from traditional cast iron pipes. Renowned for its exceptional resistance to corrosion, abrasion, and internal pressure, the ductile cast iron pipe is the optimal choice for transporting water across extensive distances under demanding high-pressure conditions. Boasting outstanding mechanical properties and an impressive lifespan, these pipes are the quintessential choice for a myriad of infrastructure projects, encompassing water distribution systems, sewer lines, and industrial pipelines.

Connection Method

 

 

1. Mechanical Joint (MJ): This method involves using mechanical joints consisting of a gland, gasket, and bolts/nuts to connect two pipes together. The gland and gasket create a watertight seal, while the bolts and nuts secure the joint.

2. Push-On Joint: In this method, the spigot end of one pipe is inserted into the socket end of another pipe. A rubber gasket in the socket provides a seal, and no additional materials or tools are required for installation.

3. Flanged Joint: Flanged joints involve connecting pipes using flanges and bolts/nuts. The flanges are attached to the ends of the pipes, and the bolts/nuts are tightened to compress a gasket between the flange faces, creating a seal.

4. Restrained Joint: Restrained joints are used in applications where pipes need to resist movement or thrust forces. These joints typically include additional components such as harnesses, rods, or restraints to secure the pipes in place.

Product Advantages

 

1. Strength and Durability: Ductile cast iron pipes have high tensile strength and are resistant to deformation, making them suitable for underground installations and withstanding external loads.
2. Corrosion Resistance: The internal lining and external coatings of ductile cast iron pipes provide excellent resistance to corrosion, prolonging the lifespan of the pipes and reducing maintenance costs.
3. Flexibility: Ductile cast iron pipes have inherent flexibility, allowing them to withstand ground movement and settle without fracturing or leaking.
4. Longevity: With proper installation and maintenance, ductile cast iron pipes can have a lifespan of over 100 years, offering long-term reliability for water distribution systems.
5. Flow Capacity: The smooth internal surface of ductile cast iron pipes minimizes friction losses and maintains consistent flow rates, ensuring efficient water distribution.
6. Environmental Sustainability: Ductile cast iron pipes are made from recycled materials and are fully recyclable at the end of their service life, contributing to environmental sustainability.
