A major leap forward in corrosion-resistant industrial piping has been achieved with the comprehensive launch of ASTM Forged Copper-Nickel C70600 (CuNi 90/10) Flanges in a Class 300 pressure rating and sizes spanning 3, 4, 5, and 6 inches. This product line, offering a complete suite of flange types including Threaded (TH), Weld Neck (WN), Slip-On (SO), and Blind (BL), with both Raised Face (RF) and Ring-Type Joint (RTJ) facings, establishes a new benchmark for durability and reliability in seawater, offshore, and chemical processing systems.
Engineered for environments where standard stainless steels succumb to chloride-induced stress corrosion cracking and pitting, these flanges leverage the proven performance of Copper-Nickel 90/10 alloy (UNS C70600). This material offers unparalleled resistance to seawater corrosion, marine biofouling, and erosion, making it the material of choice for critical infrastructure. The Class 300 rating ensures robust performance for a wide range of moderate to high-pressure applications, from shipboard cooling systems to offshore platform piping.
Technical Specifications and Manufacturing Excellence:
Each flange is precision forged to ASTM standards, a process that refines the metal grain structure to enhance mechanical strength, toughness, and homogeneity compared to cast alternatives. This forging process is critical for pressure-retaining components, ensuring integrity under cyclic loading and thermal stress. The availability of multiple facing types—RF for general gasket sealing and RTJ for high-integrity, metal-to-metal seals in severe service—provides engineers with flexible design options for any system specification.
Market Impact and Availability:
This comprehensive range of C70600 flanges is now available through certified distributors and directly from manufacturers, supported by full material traceability and compliance documentation. Industry professionals in marine engineering, offshore energy, desalination, and chemical processing can now standardize on this superior corrosion-resistant material across their piping systems, simplifying procurement and enhancing long-term system reliability.
