The Ductile Advantage

Saint-Gobain PAM UK offers ductile iron pipeline systems that give durable and reliable long-term service. This is due to the material properties of ductile iron and the advanced lining and coating systems that are available.

Ductile iron – What is it?

Ductile Iron is an iron/carbon/silicon alloy. With the addition of magnesium to the molten iron the graphite forms in spheres rather than in flakes. This transformation eliminates brittleness and produces a strong, ductile material.

Features Benefits
Inherent Strength Inherent Strength Ability to withstand extreme internal pressures and external loads.
Can be laid in poor load bearing or unstable ground.
Resistant to freeze-thaw conditions.
Excellent Impact Resistance Excellent Impact Resistance Minimum risk of damage to exposed pipework during installation.
Resistance to second comer damage or disruption.
High Safety Margin High safety factor incorporated into design.
Measured failure at more than double allowable operating pressure.
High Ring Stiffness Can be laid in poor load bearing or unstable ground (e.g. marshland).
No long term reduction in stiffness (relaxation).
Less dependant on surrounding material for support.
Flexible Joints Accommodate ground movement and limit longitudinal stresses.
Capable of angular deflection and axial withdrawal.
Ability to negotiate long radius bends without the need for additional fittings.
Corrosion Resistant Cement Mortar lining provides active internal pipe protection.
Range of external coatings available to suit a variety of aggressive ground conditions (acidic/alkaline).
Resistance to Tuberculation Linings protect against formation of iron compounds.
Eliminates long-term reduction of internal bore.
Superior Hydraulic Performance Bore is greater than that of most other materials of the same nominal diameter, results in superior discharge.
Complete Range of Fittings Comprehensive range of fittings available from stock.
Ability to meet emergency requirements without special fabrication.
Fittings, pipes, valves and joint components supplied in one single delivery.
Pipes and fittings compatible with most other materials.
Comprehensive Product Range More than 6000 standard products available.
Over 1000 products are offered within a 3-day or 10-day delivery period.
Capability to manufacture specials upon request.
Consistent High Quality Pipe manufacturing experience for over 150 years. Electronically controlled manufacturing process.
