Copper Nickel Long Welding Neck Flanges

Copper nickel long weld neck flanges are made primarily of copper (70-90%) and nickel (10-30%), with small amounts of iron and manganese for increased strength and corrosion resistance These flanges never good mechanical properties have been demonstrated, including high tensile strength, ductility and stiffness, for high compression The best of them are models for marine applications Corrosion and biofouling resistance ensures durability in marine waters and environments which is strong. Advantages include excellent thermal conductivity, ease of manufacture and minimal maintenance, making it ideal for shipbuilding, offshore platforms and heat exchangers.
