Application areas:

Municipal water supply and drainage: Ductile iron pipes are widely used in urban water supply networks, sewage treatment systems and drainage projects due to their excellent corrosion resistance and strength.

Gas transportation: used for the transportation of natural gas, liquefied petroleum gas, etc. to ensure safety and stability.

Industrial pipelines: suitable for chemical, mining, thermal pipelines and other industries, and can withstand high pressure and corrosive media.

Advantages:

High strength and good toughness: Compared with ordinary gray cast iron pipes, ductile iron pipes have higher tensile strength and toughness, and are not easy to break.

Strong corrosion resistance: Cement mortar, epoxy resin and other anti-corrosion coatings can be used on the inner and outer walls to improve durability.

Easy installation and low maintenance cost: The socket-type interface is adopted, which is easy to install and has a long life, reducing the later maintenance cost.
