Their dedication to precision, performance, and reliability makes them a go-to partner for piping systems that face seawater and other harsh environments.
Copper Nickel 70/30 Flanges are made from a copper-nickel alloy that consists of about 70% copper and 30% nickel, along with trace amounts of iron and manganese to boost corrosion resistance and strength. These flanges are mechanically impressive, offering excellent tensile and yield strength, along with high ductility and toughness, which allows them to handle pressure and temperature changes effectively. Their outstanding resistance to seawater corrosion, biofouling, and erosion guarantees long-lasting performance in marine and offshore piping systems. Plus, the material is easy to weld and fabricate, making installation and maintenance a breeze.
