Product Overview

Ductile Iron Sewage Pipes are specially designed for municipal and industrial wastewater systems, combining the high strength of ductile iron with advanced corrosion protection. The pipes feature:

• Zinc plus red external anticorrosive coating – provides wear resistance and protects against external corrosion.

• High alumina cement internal anti-corrosion coating – ensures long-term resistance to aggressive sewage and special soil conditions.

These pipes are ideal for challenging environments, including municipal sewage pressure networks, pump stations, sewage treatment plants, and industrial pipelines transporting polyphenols, cyanides, or other corrosive substances.

Key Features

• High wear resistance – zinc-red external coating withstands abrasive soil and handling conditions.

• Excellent internal corrosion protection – high alumina cement lining resists aggressive wastewater.

• Durable ductile iron pipe body – maintains mechanical strength and pressure resistance.

• Suitable for high-pressure sewage applications – pump stations and pressure pipelines.

• Adapted for industrial wastewater – resists corrosion from polyphenols, cyanides, and similar substances.

• Long service life and low maintenance – designed for reliability in demanding conditions.

Typical Applications

• Municipal sewage pressure pipe networks

• Sewage treatment plants and pumping stations

• Industrial wastewater pipelines containing corrosive chemicals

• Areas with challenging soil conditions

• High-wear or high-pressure sewer applications

Why Choose Ductile Iron Sewage Pipes?

Ductile iron sewage pipes combine exceptional mechanical strength with specialized anti-corrosion coatings. The zinc-red external layer and high alumina cement internal lining provide durability and long-term protection against aggressive sewage and harsh soil conditions. This ensures reliable performance for municipal and industrial wastewater systems with high requirements for corrosion resistance and pressure handling.
