Tanvir Nickel Alloys, located in Cairo, Egypt, stands out as a top manufacturer and supplier of high-quality Copper Nickel 70/30 Pipes, crafted for exceptional performance in tough marine and industrial settings. With a commitment to rigorous quality control and precise manufacturing, these pipes adhere to international standards for durability and resistance to corrosion. Tanvir Nickel Alloys caters to a diverse array of industries, including shipbuilding, offshore oil and gas, desalination, and chemical processing, delivering dependable piping solutions that can endure harsh seawater and chemical exposure over the long haul.
The Copper Nickel 70/30 Pipes are composed of an alloy that features around 70% copper and 30% nickel, along with small amounts of iron and manganese to boost mechanical strength and corrosion resistance. These pipes are known for their impressive resistance to pitting, stress corrosion cracking, and biofouling in both seawater and brackish water environments. They typically showcase mechanical properties such as tensile strength ranging from 275 to 350 MPa, yield strength between 105 and 150 MPa, and good ductility, which helps them maintain their integrity under varying pressures and temperatures. Their thermal stability and erosion resistance make them perfect for challenging service conditions.
