Ductile Iron Introduction

♦ Ductile iron are robust, can withstand mechanical stress and physical abuse, can be laid in unfavorable terrain and operating conditions and work without failure offering a long service life. 

Ductile iron pipe, fittings and accessories are used for the transmission of potable water and waste water across a number of areas such as drinking water networks, sewerage networks, fire-fighting systems and HVAC water systems.
 

♦ Advantage of ductile iron pipes and fittings:

• High tensile strength, good elastic module and excellent ductility, making it suitable for high stress applications and where pressure surge may be experienced.

• High corrosion resistance.

• Excellent hydraulic flow.

• High working pressure compared to other types of pipes.

• Ease of installation.

• Long lifetime.

• Can accommodate ground movement. 

♦ Coating:

External coating:

BS EN545 pipe: metallic zinc coating with finishing layer

BS EN545 fittings: zinc rich paint coating with finishing layer

BS EN598 pipe & fittings: epoxy paint 

♦ Internal lining protection

BS EN545: sulphate resistant cement mortar lining

BS EN598: high aluminium cement mortar lining
