Also, rapid industrialization in emerging economies, coupled with the surge in environmental awareness, can fuel market growth further.
Ductile Iron Pipes are centrifugally cast-iron pipes manufactured using ductile cast iron, a type of iron known for its high strength, elasticity, and impact resistance. These pipes are extensively used in water and wastewater transportation systems due to their durability, corrosion resistance (often enhanced by linings/coatings), and long service life. Ductile iron offers better performance compared to traditional gray cast iron due to its nodular graphite inclusions. There is an increasing focus on eco-friendly water management practices; hence, these iron pipes are preferred for their long service life and durability, which makes them a crucial choice among manufacturers.
The government is increasingly promoting the market through various initiatives and infrastructure projects focusing on water, sanitation, and management. The efforts, such as Smart Cities Mission and Al Jeevan Mission, directly fuel the demand for ductile iron pipes because of their reliability and durability in wastewater management and water distribution.
The Indian government is rapidly investing in water infrastructure projects such as the Smart Cities Mission and Jal Jeevan Mission (JJM), both of which depend on ductile iron pipes for water supply and sanitation. Emerging economies with increasing populations and infrastructure demand are also witnessing growing demand for ductile iron pipes.
