Water and wastewater is sub-divided into underground and surface.

By application, wastewater treatment is expected to hold a significant ductile iron pipes market share owing to the expansion of wastewater treatment plants

According to UN-Water, about 70% of the wastewater is treated by high-income countries, whereas wastewater treatment constitutes 38% in upper-middle-income countries and 28% in lower-middle-income countries. Changing climatic conditions and lesser availability of potable water necessitate the requirement of wastewater treatment facilities and efficient pipelines to distribute water to the required areas. The expanding network of wastewater treatment plants is expected to drive the ductile iron pipes market expansion during the forecast period.

Industries, such as chemical and automotive are dominant consumers of DI pipes. The pipes offer the industrial sector the benefits of strength, toughness, and resistance to corrosion and chemical attacks. The global chemical production is expected to grow by 2.7% during the forecast period. Further, the global automotive sector is expected to increase production to 122.83 million units by 2030.

According to the ductile iron pipes market analysis, the growing population, urbanisation, and climate change are contributing to an increased demand for water resources. The need for efficient transport of water for irrigation purposes is increasing the use of pipelines. About 20% of the total cultivated land is represented by irrigated agriculture and contributes to about 40% of the total food produced globally.

Ductile iron pipes are considered reliable and high-performing. Hence, they significantly contribute to the smooth operation and productivity of mining and quarrying activities. Some of the key companies offering ductile iron pipes for mining purposes include Kurimoto Ltd, and DZ Amanzi Pipeline Systems, among others.

Socket and spigot joint type is expected to grow at a considerable rate during the forecast period

According to ductile iron pipes market insights, the socket and spigot joint type is expected to grow significantly in the market. Ductile iron pipes composed of a spigot and socket, with a rubber gasket for sealing, are flexible. These allow a desirable amount of deflection, expansion, and contraction. Owing to this flexibility, small curves in a pipeline can be easily accommodated, without the use of bends.

Flanged pipes are generally deployed for above-ground transportation of water where rigid and restrained joints are needed.

Competitive Landscape

The market players set themselves apart by offering superior product quality, cutting-edge technologies, recycled raw materials, and providing comprehensive technical support and after-sales services.

Other key players in the ductile iron pipes market include American Cast Iron Pipe Company, U.S. Pipe, Inc., Xinxing Ductile Iron Pipes Co., Ltd., Welspun Corp Limited, China National Building Material Co., Ltd, and Electrosteel Castings Limited, among others.

Global Ductile Iron Pipes Market Analysis by Region

Asia Pacific is a prominent region in the ductile iron pipes market outlook due to an increased demand for smart cities and sanitation infrastructure

According to the ductile iron pipes market report, the developing economies in Asia Pacific, like India are significantly contributing to the growth of the market owing to increased demand for sanitation infrastructure. Further, the growing number of smart cities, such as Kuala Lumpur, Hong Kong, and Taipei City, among others, are also fuelling the demand for extensive pipeline networks.

The key ductile iron pipe manufacturers in North America include AMERICAN Ductile Iron Pipe, Canada Pipe Company, LTD., McWane Ductile, and U.S. Pipe. Around 75% of the pipelines in the water distribution networks of Toronto are made of ductile iron. Further, DI pipes are less prone to failure compared to PVC pipes owing to their high tensile and bending strength and impact resistance, impacting the ductile iron pipes market growth. The use of ductile iron pipes in Canadian public water supply systems has increased the reliability of water supply to Canadians.

Further, the European ductile iron pipes market is driven by the increasing sustainability concerns on inland water transport. This aids the adoption of ductile iron pipes due to their recyclability and energy savings. Further, the UK also holds a large geothermal potential in areas, such as East Lindsey, Redcar and Cleveland, Northumberland, Middlesbrough, Hartlepool, and Bassetlaw, among others. The high-temperature resistance of ductile iron pipes makes them ideal for carrying hot water or steam in geothermal plants.
