Product Overview

Ductile Iron Special Coating Pipes are designed by Tiegu to meet diverse customer requirements, combining the strength and durability of ductile iron with advanced corrosion protection. Various high-performance internal and external coatings are available, including:

• Zinc-aluminum alloy external anti-corrosion coating

• Polyurethane internal and external coatings

• Epoxy resin layers

• Ceramic coatings

• Epoxy nano ceramic polymer linings

These coatings allow the pipes to operate reliably in challenging environments such as wet areas (ponds, swamps), saline-alkali soils, clay with low permeability, and industrial parks. Special coating ductile iron pipes provide long-term corrosion protection while maintaining the mechanical strength and integrity of ductile iron.

Key Features

• High-performance anti-corrosion coatings – multiple options for internal and external protection.

• Durable ductile iron pipe body – retains mechanical strength and toughness.

• Suitable for harsh environments – wet, saline, or clay-rich soils; industrial zones.

• Enhanced service life – coatings prevent rust, corrosion, and scaling.

• Flexible application – can be customized according to specific project requirements.

• Low maintenance – coatings reduce the need for repairs and prolong operational life.

Typical Applications

• Municipal water supply pipelines in wet or saline areas

• Industrial parks and factory pipeline systems

• Drainage and irrigation pipelines in ponds and swamps

• Infrastructure in challenging soil conditions

• Projects requiring extended corrosion resistance
