Customer Challenges
Improving Connection Methods
Improving Connection Methods
Traditional welding techniques often present certain challenges during construction. Welding requires significant manpower and time, and the quality of the weld is heavily influenced by the skill level of the operator, leading to a higher likelihood of substandard welding quality.
Extending Pipeline Service Life
Extending Pipeline Service Life
Although traditional steel pipes boast high strength, their corrosion resistance is relatively poor, making them prone to rust. This necessitates frequent maintenance and replacement, resulting in a shorter service life.

Socket Connection
Socket connections are simpler to operate and allow for faster construction. The process involves inserting the spigot end of the pipe into the socket end, sealing it with a rubber gasket, and then tightening it using specialized tools. This connection method offers excellent sealing performance, reducing the risk of water leakage. Additionally, socket connections are more cost-effective in terms of construction expenses, making them suitable for large-scale applications.
Socket Connection
Material Optimization
The spheroidal graphite structure within the wall of ductile iron pipes effectively reduces stress concentration, enhancing the material's toughness and strength. This enables ductile iron pipes to withstand higher internal and external pressures as well as impact forces, significantly extending the service life of the pipeline network.
