Pressure Class (PN) Rated Ductile Iron Pipes are essential components in modern water and wastewater infrastructure. These pipes are categorized based on their nominal pressure handling capacity, with common classifications being PN10, PN16, and PN25. PN10 pipes are suitable for standard water distribution systems, while PN16 and PN25 are used in high-pressure systems such as fire fighting mains, industrial processing units, and transmission mains. These classifications ensure that engineers and infrastructure planners can choose pipes that match the operational pressure requirements of their specific application.
Riddhi Siddhi Impex, a trusted manufacturer and domestic supplier of ductile iron products, specializes in delivering high-quality Pressure Class (PN) Rated Ductile Iron Pipes across India. The company follows strict manufacturing standards such as IS 8329, ISO 2531, and EN 545, ensuring the pipes meet both Indian and international quality benchmarks. Their pressure-rated DI pipes are manufactured using centrifugal casting techniques and are tested for hydraulic pressure and dimensional accuracy to guarantee long service life..
These pipes are lined internally with cement mortar lining for enhanced corrosion resistance and can be externally coated with zinc, bitumen, or epoxy based on the application environment. PN-rated ductile iron pipes offer excellent mechanical strength, ductility, and resistance to both internal water pressure and external loads. Whether it's a high-rise water supply system or an industrial coolant system, these pipes ensure secure and efficient fluid transportation.
Riddhi Siddhi Impex proudly serves customers in major Indian cities including Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, and Ahmedabad. These urban centers demand robust and reliable piping systems for residential, municipal, and commercial use. The pressure-rated DI pipes supplied here are a backbone for drinking water projects, underground networks, and smart city developments due to their strength and long-term reliability.
In addition to metro cities, Riddhi Siddhi Impex is a key domestic supplier in tier-2 and tier-3 cities such as Surat, Vadodara, Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, and Chandigarh. These cities are seeing significant infrastructure investment and industrial growth, leading to a sharp rise in demand for pressure-rated pipelines that can withstand variable water pressure and harsh climatic conditions.
