DI Pipe K7 in Chaibasa

Ductile Iron Pipes, or DI Pipes, are among the most useful and long-lasting piping solutions for water supply, sewage, and industrial fluid systems. Made from ductile cast iron, these pipes combine the strength of steel with the corrosion resistance of iron, making them ideal for underground and high-pressure applications.

If you're working on urban infrastructure, water distribution networks, or industrial drainage projects, DI pipes are often the first choice because of their durability and performance in harsh conditions.

Key Properties of DI Pipe

• High Tensile and Impact Strength: Ductile iron has excellent flexibility, reducing the risk of cracks under stress.
• Corrosion Resistance: With internal linings like cement mortar and external coatings like zinc or bitumen, DI pipes withstand corrosion better than the usual CI (Cast Iron) pipes.
• Leak-Proof Jointing Systems: Push-on and socket-spigot joints give tight seals without welding.
• High Pressure Handling: Suitable for pressure ratings up to PN25, ideal for both gravity-fed and pressurized systems.
• Longevity: With proper installation, DI pipes can last 50–100 years even in aggressive soils.

Industrial Applications of DI Pipe

1. Municipal Water Supply: Quite common in city pipelines and water distribution grids because of their long service life.
2. Sewerage and Drainage Systems: Handle both stormwater and wastewater with much less maintenance.
3. Industrial Effluent Systems: Used in power plants, steel plants, and chemical factories for fluid transport.
4. Firefighting Networks: Used in fire suppression systems because of their strength and pressure tolerance.
5. Irrigation and Rural Water Supply: Especially in state-sponsored schemes where long-distance underground piping is required.

DI Pipe Market Trends and Supply Chain

The Indian Ductile Iron pipe market is seeing good growth, driven by infrastructure development and water supply projects. India has now become a leading exporter of DI pipes, accounting for 98% of global exports under HSN code 73071120. 

The Indian DI pipe market was valued at approximately USD 3.19 billion in 2024. It is projected to grow at a compound annual growth rate (CAGR) of 12.5%, reaching around USD 10.36 billion by 2034. This growth is fuelled by urbanization, increased demand for potable water, and substantial investments in water infrastructure.

Programs like the Jal Jeevan Mission and Smart Cities Mission are today boosting demand for DI pipes, as they are aiming to improve water supply and sanitation across the country.

Major manufacturers of DI pipes include Electrosteel, Jindal SAW, Tata Metaliks, Srikalahasthi Pipes. Electrosteel Castings is about to complete its expansion to a 1 million ton DI pipe manufacturing capacity, which shows strong market demand and future growth prospects.

Recent tenders across various Indian states, including Haryana and Kerala, for the supply and laying of DI pipes highlight the ongoing infrastructure projects and the sustained demand for DI piping solutions. 

DI Pipe Prices

DI pipe prices today depend on the grade and where you are buying. For example, as of May 13, 2025, K7 grade DI pipes in places like Kharagpur, Durgapur, and Gandhidham were going for Rs 12,399 per meter. K9 grade ones in Anjar and Chaibasa are a bit pricier at Rs 13,802 per meter.

DI Pipe Rates Today 

DI pipe rate updates are usually issued by manufacturers or authorized dealers on a weekly or daily basis.

Today's DI pipe prices vary based on:

• Size (e.g., DN100, DN200, DN300, etc.)
• Pressure rating (PN10, PN16, PN25)
• Lining/coating (Cement mortar lined, bitumen coated, zinc-aluminium coated)
• Brand and factory origin
• Region and delivery distance

DI Pipe Price Forecast 

The Indian DI pipe market is poised for continued growth because of robust infrastructure development and increasing export opportunities. Stakeholders should monitor raw material costs and global market trends to navigate potential challenges.

Today, DI pipes have got a preference over PVC or steel in critical underground pipelines. There’s a growing use in tier-2 and tier-3 cities for long-term infrastructure upgrades.

DI pipe prices are expected to remain steady unless raw material prices rise again. Continued demand from government water and sanitation projects will support price stability. Any spike in pig iron, foundry coke, or energy costs may push prices upward.

Factors that Influence DI Pipe Prices in India

• Pig Iron and Coke Prices: Raw material cost is the biggest factor in DI pipe pricing.
• Infrastructure Demand: Government projects directly affect demand and pricing.
• Manufacturing Capacity: Limited DI pipe production in India can sometimes cause bottlenecks.
• Freight and Handling: Being heavy, these pipes carry high logistics costs.
• Coating and Lining Customization: Each variation adds cost based on application needs.
