Product Overview

PE liner pipes are a new type of ductile iron pipe offered by Tiegu, combining the mechanical strength of ductile iron with the corrosion resistance and sanitary benefits of polyethylene. The inner PE liner prevents scaling, reduces friction, and ensures excellent water quality, making it suitable for direct drinking water supply.

These pipes are highly resistant to corrosion from special media, including seawater, urban sewage, and other aggressive liquids, while maintaining the structural integrity and durability of ductile iron. PE liner pipes are widely used in municipal drinking water systems and other applications requiring hygienic, corrosion-resistant pipelines.

Key Features

• Combination of ductile iron and polyethylene – mechanical strength of ductile iron with corrosion resistance and hygiene of PE liner.

• Excellent sanitary performance – inner surface smooth, prevents scaling and layering.

• Suitable for drinking water – meets direct drinking water standards.

• Corrosion-resistant – resistant to seawater, urban sewage, and other aggressive media.

• Durable and long-lasting – maintains the structural integrity of ductile iron pipe.

• Low maintenance – smooth PE lining reduces friction and biofilm formation.

Typical Applications

• Drinking water pipelines

• Direct potable water systems

• Seawater and wastewater transportation

• Municipal water supply networks

• Industrial water pipelines requiring high hygiene standards

Why Choose Ductile Iron PE Liner Pipes?

Ductile iron PE liner pipes combine the best properties of ductile iron and polyethylene: the high strength and durability of ductile iron, and the corrosion resistance, hygienic inner surface, and smooth flow characteristics of PE. This combination ensures long-term reliability, safe drinking water supply, and resistance to challenging environmental conditions.
