Ductile iron pipes are widely used in modern pipeline engineering due to their excellent performance. The main uses include:

Water supply system (drinking water transportation):

This is one of the main uses. Ductile iron pipes have high strength, good toughness, pressure resistance, and corrosion resistance (especially with cement mortar or epoxy resin lining), which can effectively ensure the safe, reliable and long-term stable operation of drinking water transportation.

It is suitable for urban tap water mains, water distribution networks, community water supply, etc.

Drainage system (sewage, rainwater transportation):

It is also widely used in municipal sewage networks, rainwater drainage systems and industrial wastewater transportation.

Its good pressure bearing capacity, corrosion resistance (especially to corrosive gases such as hydrogen sulfide) and long service life make it one of the ideal pipes for sewage transportation.

Fire protection system:

It is used in fire protection water supply networks, requiring pipelines to have extremely high reliability and pressure bearing capacity. The strength and toughness of ductile iron pipes fully meet the requirements of fire protection systems.

Industrial pipelines:

In factories, mines, oil fields and other industrial fields, it is used to transport industrial water, cooling water, certain chemical media (special lining may be required according to the characteristics of the media), etc.

It has strong resistance to external pressure and is particularly suitable for occasions that require a large burial depth or heavy ground loads.

Water supply trunk line:

It is used for long-distance water supply projects, such as water diversion projects, water transfer projects, and raw water transportation. It has high pressure bearing capacity, good interface sealing, and long service life. It is a commonly used pipe material for large-scale water supply projects.

Irrigation system:

In large-scale agricultural irrigation projects, especially the main canal or the pipeline part that needs to bear pressure, ductile iron pipes are also often used.
