DUCTILE IRON (DI) PIPES

 Ductile iron pipe is generally suitable for all pipeline applications.

Advantages

• Good corrosion resistance
• Wide variety of available fittings and joints
• Wide range of available thicknesses
• Good resistance to water-hammer
• High strength for supporting earth loads

Disadvantages

• Relatively expensive 
• Difficult to weld
• May require wrapping or cathodic protection in corrosive soils

Although, fairly resistance to corrosion, internal and external protective coatings with bitumen or coal tar are standards. 

For aggressive water or soils, further protection such as cement motar resin internal lining and external bituminous sheathing, protective tape or polythene sleeving may be necessary.
