♦ 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
