1. Material Composition

• Manufactured from high-grade ductile cast iron with a spheroidal graphite structure.
• Minimum tensile strength: ≥420 MPa
• Minimum yield strength: ≥300 MPa
• Designed to provide high impact resistance and suitable elongation properties.

2. Coating & Lining

External Coating

• Metallic zinc coating for corrosion protection.
• Bitumen or epoxy finishing layer for additional protection and durability.

Internal Lining

• Cement mortar lining (CML) suitable for potable-water and other approved applications.
• Provides a smooth internal surface and helps reduce hydraulic friction.

3. Jointing System

Available joint configurations include:

• Push-on joints
• Mechanical joints
• Flanged ends

The jointing systems are designed to provide secure, leak-resistant and flexible connections suitable for underground pipeline applications.

4. Pressure / Class

Available classes include:

• K7
• K9
• K12

The applicable pressure class shall be selected according to the project requirements and applicable standard.

5. Available Sizes

Nominal diameters:

DN 80 mm to DN 1200 mm

Standard pipe lengths may be supplied in approximately 5.5 to 6 metres, depending on diameter, standard and manufacturer specification.

6. Performance Advantages

High Strength & Load-Bearing Capacity

Ductile iron pipes provide high mechanical strength and are suitable for underground applications subject to appropriate design and installation.

Corrosion Protection

Zinc coating with a suitable finishing layer provides protection against external corrosion. Additional protection may be specified according to soil and environmental conditions.

Hydraulic Efficiency

The smooth internal cement mortar lining provides a relatively smooth flow surface and helps reduce friction losses.

Long Service Life

When properly specified, installed and protected against the applicable environmental conditions, ductile iron pipeline systems can provide a long service life.

Ease of Installation

Push-on joint systems can facilitate relatively quick installation and accommodate normal pipeline movement and alignment requirements.

7. Applications

Ductile iron pipes are suitable for:

• Municipal and urban drinking-water distribution
• Sewerage and wastewater networks
• Industrial process pipelines
• Irrigation systems
• Hydropower projects
• Firefighting water lines
• Stormwater and drainage systems

8. Standards

Products can be manufactured and supplied in accordance with applicable standards, including:

• ISO 2531
• EN 545
• IS 8329

The exact standard, class, coating, lining, joint type and dimensions shall be confirmed according to the purchase order and project requirements.
