Manufacturer, Supplier & Exporter of PVC Coated Ductile Iron
Riddhi Siddhi Impex is a leading manufacturer and domestic supplier of PVC Coated Ductile Iron Pipes in India. These pipes are engineered to deliver superior performance in water, wastewater, industrial, and utility applications. By combining the strength and flexibility of ductile iron with a durable PVC external coating, the company offers a product that withstands harsh environmental conditions, corrosion, and physical impacts—making it ideal for underground and exposed installations
Ductile Iron (DI) is a robust material known for its high tensile strength and impact resistance, far superior to traditional cast iron. When coated with PVC (Polyvinyl Chloride), these pipes gain an additional layer of protection against corrosion, UV radiation, chemical attack, and mechanical wear. This dual protection ensures long-term performance and minimal maintenance in the field. Riddhi Siddhi Impex follows stringent quality control procedures, ensuring every pipe meets IS and international standards.
Serving a broad range of industries—from municipal water systems to power plants and infrastructure projects—Riddhi Siddhi Impex supplies PVC coated ductile iron pipes in various diameters, lengths, and pressure ratings. These pipes are widely used in water supply networks, sewer systems, stormwater management, and industrial process piping. Their PVC coating not only extends the pipe’s lifespan but also makes installation easier by reducing friction and handling damage.
Riddhi Siddhi Impex has built a strong presence in key Indian markets. Their supply network covers major metropolitan cities such as Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, and Vadodara. These cities, which are at the forefront of India’s industrial and urban development, rely heavily on durable and long-lasting piping systems for infrastructure upgrades, smart city projects, and municipal utilities.
Apart from the metro cities, the company has expanded its supply chain to tier-2 and industrial cities like Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, and Varanasi. These areas have seen significant investments in infrastructure, sanitation, and water distribution projects, where PVC coated ductile iron pipes are an essential component due to their reliability, ease of installation, and low lifecycle cost.
