Ductile Iron Flanges Manufacturer in India
Nitech Stainless Inc is a leading Ductile Iron Flanges Manufacturer in India. Ductile Iron flanges are flanges made from ductile iron, a material known for its high strength, excellent corrosion resistance, and good ductility. Unlike traditional cast iron, ductile iron (also known as nodular cast iron) contains small amounts of graphite, which gives it increased flexibility and strength. This makes ductile iron flanges ideal for a wide range of industrial applications, particularly where durability and performance are required under high-pressure and corrosive conditions. Ductile Iron flanges are commonly used in water treatment, sewage, and chemical processing industries, as well as in the construction of pipelines and infrastructure.
Ductile Iron flanges are highly resistant to cracking and have superior impact resistance compared to regular cast iron, making them suitable for systems that experience thermal or mechanical stress. They are often used in configurations such as slip-on, weld neck, and blind flanges to connect pipes securely in various piping systems. The material’s ability to withstand corrosion from water, chemicals, and other harsh environments, combined with its ability to maintain strength under pressure, makes ductile iron flanges a reliable choice for long-lasting, leak-proof connections.
