Vipul Pipes and Tubes, an organization located in Chennai, India, is a well-known manufacturer and supplier of high-quality Copper Nickel 70/30 Pipes with exceptional corrosion resistance, particularly in seawater and marine applications. These pipes are designed to provide better performance in highly corrosive and high-pressure applications, which makes them suitable for naval, industrial, and offshore applications. Vipul Pipes and Tubes adheres to strict quality procedures and employs innovative manufacturing processes for supplying dependable, long-lasting, and dimensionally correct piping solutions. With a customer-centric strategy, the company meets global industries needing reliable, long-lasting materials for critical operating systems.
Copper Nickel 70/30 Pipes contain 70% Copper and 30% Nickel, with minor additions of Iron (0.4–1%) and Manganese (0.5–1%) to increase strength and corrosion resistance. The pipes show superior resistance to biofouling, stress corrosion cracking, and erosion in seawater. They have a tensile strength of 500–600 MPa, yield strength of 170–260 MPa, and elongation of 30–45%. Their mechanical strength, combined with excellent thermal stability and weldability, renders them eminently suitable for challenging uses in marine, offshore, and chemical conditions.
