Manufactured from copper-nickel alloys like Cu-Ni 90/10 (C70600) and Cu-Ni 70/30 (C71500), Copper Nickel Orifice Flanges boast remarkable resistance to seawater corrosion, biofouling, and stress cracking. These alloys not only provide impressive mechanical properties, with tensile strength ranging from 275–345 MPa, but also exhibit excellent ductility, making them ideal for medium-pressure applications. The flanges are designed with precision boreholes for accurate flow measurement and can come equipped with jack screws and tapping points according to standard specifications. Their unique metallurgical makeup ensures they perform reliably over the long haul in saline and corrosive environments where traditional steel might struggle.
