DI Pipes & Fittings
Ductile Casted Iron is considered one of the most reliable and trusted medium in transporting and distributing potable water
DUCTILE IRON PIPES
The strength, long service life and durability of Ductile Iron Pipe is widely known throught the infrasturcture industry. Ductile Iron was an improvement over its predecessor, gray Cast Iron pipe.
Ductile Iron not only retains all of Cast Iron’s attractive qualities, such as machinability and corrosion resistance, but also provides additional strength, toughness, and ductility. It is lighter, stronger, more durable and more cost effective than Cast Iron.
Although its chemical properties are similar to those of Cast Iron, Ductile Iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control.
WHY USE DUCTILE IRON PIPES?
DI is Known for its Exceptional Tensile Strength and its Ability to sustain Bearing Pressure
East to Install with Minimal installation cost
High Impact and Corrosion resistant with High Bursting Strength
DI Pipes can withstand Severe Crushing Loads with Excellent Beam Strength
A Zero Maintenance product that saves costs by requiring low pumping pressure with great Hydraulic Features and extensive range of fittings and accessories
Although its chemical properties are similar to those of Cast Iron, Ductile Iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control.
