Ductile Iron Flanged Pipes

The Flanged joint is a rigid pipe joint typically used in above ground applications such as treatment works, pumping stations or fire mains.

Electrosteel principally manufacture Flanged pipes using 2 methods: Welded Flange Pipes - Flanges are machined to an established 'undersize' specific to the pipe spigot, heated and shrink fitted to the pipe barrel. Subsequently they are welded to create a strong jointing system. Cast Flange Pipes - These pipes are cast in our foundry as a single unit using our advanced Lost Foam method

Note 

Due to the rigid nature of the joint and the risk of excessive bending moment being imposed it is advised that flanged pipework is not used in buried pipelines.

Applications

As above ground 'restrained' joint

Flanged Joints are rigid but can act as a restrained joint, reducing the requirement of thrust blocks and external restraining devices. However it should be noted that the use of Flanged Joints as a buried pipeline is not recommended.   Over ground and exposed installations The strength and impact resistance of ductile iron make the flanged joint system ideal for over ground pipelines and crossovers, such as pillars on a canal or other water bodies, roads or bridges etc

Vertical pipelines

Interconnection and connection for accessories

Temporary Installations

Applications where pipelines need to be disengaged or transferred from one location to the other.

Advantages

Electrosteel's Ductile Iron Flanged Pipes have several advantages over other flanged pipes available on the market. Some of these are highlighted below:

• Stronger: Due to higher tensile strength and better impact resistance.

• Safer: Higher factor of safety against pressure fluctuations, water hammer and outside impacts.

• Lighter to use: Ductile Iron Flanged Pipes are lighter, which reduces handling and transportation cost.

• Better casting process: Centrifugal casting of pipe barrel ensures compact casting and eliminates defects like blowholes, pinholes, slag inclusion and core displacement.

• Reduced pumping costs: Our pipes are centrifugally cement mortar lined, and the smooth finish reduces friction loss.

• Corrosion resistance: Internal cement lining and external Zinc / Bitumen coating offers excellent protection against corrosion.

• Dimensional accuracy: Centrifugal casting ensures uniform wall thickness and excellent surface finish.
