Shanghai, June 4, 2025 — TOBO Industrial (Shanghai) Co., Ltd., a global leader in pipeline connection solutions, has officially launched a new line of Copper Nickel 70/30 Flanges designed for the most demanding marine, offshore, and industrial environments. These flanges, manufactured to ASME B564 N07060 standards, feature Ring Joint (RJ) facing and meet the rigorous Class 1500 pressure rating, offering both exceptional corrosion resistance and reliable high-pressure performance.
As infrastructure and energy projects push further into harsh environments, especially in coastal and offshore regions, the need for dependable, long-lasting materials becomes critical. TOBO’s new Cu-Ni 70/30 flanges are tailored to answer that call, combining high material integrity, resistance to aggressive seawater conditions, and precision engineering.
What Makes Copper Nickel 70/30 Ideal for Harsh Environments?
The 70/30 Copper Nickel alloy (70% Cu, 30% Ni) is widely regarded as one of the most corrosion-resistant alloys for use in saltwater and high-moisture environments. This material not only resists general corrosion and pitting but is also highly resistant to stress-corrosion cracking and biofouling, a major concern in marine applications.
TOBO’s Copper Nickel flanges are particularly suited for use in:
Seawater cooling systems
Desalination plants
Marine and naval shipbuilding
Offshore oil and gas platforms
Coastal power stations
Heat exchangers and condensers
Thanks to the high nickel content, these flanges can operate in temperatures up to 300°C while maintaining strength, ductility, and corrosion resistance.
Engineered for Pressure: Class 1500 and RJ Facing
The Class 1500 rating means these flanges are designed to handle pressures up to 1500 psi, making them ideal for critical piping systems that must perform under extreme operating conditions. The Ring Joint (RJ) facing further enhances sealing reliability. This design uses a metal ring gasket seated in precision-machined grooves to create a tight, leak-proof seal — even under cyclic temperature and pressure loads.
This flange type is favored in oil, gas, and chemical process industries where system failure is not an option. The RJ design ensures that even under high-vibration conditions, such as those found on offshore rigs or in shipboard systems, sealing integrity is maintained.
Compliant with ASME B564 N07060 Standards
TOBO’s 70/30 Copper Nickel flanges comply with ASME B564, which governs the standards for wrought nickel and nickel alloy forgings. The use of UNS N07060 grade material ensures consistency in composition, strength, and corrosion behavior across all flanges produced. These flanges are available in a wide range of sizes, from ½" to 24", and can be custom-machined to client specifications.
Each unit undergoes strict inspection processes including:
Positive Material Identification (PMI)
Hydrostatic pressure testing
Ultrasonic and radiographic testing
Dimensional verification
Surface and coating inspections
Customers can also request third-party certification from organizations like Lloyd's Register, ABS, or DNV upon request.
Sustainability and Lifecycle Value
Beyond performance, Copper Nickel alloys also offer exceptional lifecycle value. Because these materials resist corrosion and fouling without chemical coatings or cathodic protection, they require significantly less maintenance over time. This reduces both operating costs and environmental impact, especially in ecologically sensitive zones like oceans and coastal waters.
In addition, Copper Nickel is fully recyclable, making it an attractive material choice for engineers and procurement managers looking to meet sustainability goals without compromising on performance.
TOBO’s Commitment to Innovation and Quality
For over a decade, TOBO has built its reputation on delivering reliable, high-performance metal components to customers across 50+ countries. With state-of-the-art manufacturing facilities, in-house metallurgical expertise, and ISO-certified quality systems, TOBO continues to lead the industry in innovation, quality control, and customer satisfaction.
According to TOBO’s Chief Technical Officer, Mr. Zhao Liang, “Our new Copper Nickel 70/30 RJ Class 1500 flanges are the result of extensive research and field testing. We’ve developed these to serve industries where failure is not an option. Whether you're managing a naval fleet or operating an offshore platform, these flanges provide the strength and peace of mind you need.”
Availability and Ordering
The Copper Nickel 70/30 Flanges RJ CL1500 B564 N07060 are now available for global ordering through TOBO’s official distribution channels and e-commerce platforms. TOBO offers full customization support, including tailored dimensions, drilled or blank options, and expedited delivery for urgent projects.
For large-scale industrial projects, TOBO provides technical documentation, installation guidance, and logistics coordination, helping clients maintain project schedules and budget requirements.
Conclusion
With the introduction of the Copper Nickel 70/30 RJ CL1500 B564 N07060 flanges, TOBO continues to set the standard for durability, precision, and corrosion resistance in piping systems. Designed to thrive in some of the world’s most hostile operating environments, these flanges provide a long-lasting, low-maintenance solution for industries that demand nothing less than excellence.
