Rithav Pipes and Tubes, based in Delhi, India, stands out as a reputable manufacturer and supplier of top-notch Copper Nickel ERW (Electric Resistance Welded) Pipes. Renowned for providing dependable and corrosion-resistant piping solutions, Rithav serves essential needs in marine, offshore, and industrial sectors. The company employs cutting-edge welding and forming techniques to guarantee precise dimensions, robust weld seams, and a superb surface finish. With a strong commitment to quality assurance and customer satisfaction, Rithav Pipes and Tubes is dedicated to delivering Copper Nickel ERW Pipes that align with both national and international performance standards.
These Copper Nickel ERW Pipes are primarily made up of copper (usually around 90%) and nickel (10%), with additional elements like iron and manganese to boost strength and corrosion resistance. They boast impressive mechanical properties, featuring a tensile strength ranging from 310 to 500 MPa, along with good elongation and impact resistance. The electric resistance welding process ensures consistent wall thickness, tight tolerances, and smooth internal surfaces. Copper Nickel ERW Pipes are known for their exceptional resistance to biofouling, seawater corrosion, and stress cracking, making them incredibly durable and efficient for both structural and fluid transport applications in challenging environments.
