Product Description
Factory Price CuNi 70/30 Socket Weld Flange Class150, ASME B16.5 Forged C71500 RF
1.Product Description
The Copper Nickel Flange is a premium-grade pipe fitting manufactured from copper-nickel alloy, standard grades 90/10 (UNS C70600) and 70/30 (UNS C71500). It provides a reliable, leak-proof bolted connection between pipes, valves, pumps, and other equipment. These flanges are specifically engineered for demanding applications involving seawater, brackish water, and other aggressive fluids, where long service life and low maintenance are critical.
2. Applications
-
Shipbuilding: Seawater cooling, ballast, firefighting, and sanitation piping systems.
-
Offshore Oil & Gas: Process piping, firewater systems, and utility lines on fixed and floating platforms.
-
Desalination: Brine recirculation, feed water, and blowdown lines in SWRO, MSF, and MED plants.
-
Power Plants: Cooling water intake and discharge systems, auxiliary cooling circuits.
-
Industrial: Heat exchangers, condensers, evaporators, and piping for salt solutions.
3. Product Functions
-
Pipe Joining: Provides secure, detachable connections for easy assembly and disassembly of piping systems.
-
Pressure Retention: With proper gasket and bolting, maintains system pressure without leakage.
-
System Isolation: Blind flanges allow safe isolation of pipe sections for maintenance or modification.
-
Stress Transition: Weld neck flanges provide smooth stress transfer from pipe to flange, ideal for cyclic or high-temperature service.
-
Access Point: Flanged connections serve as access points for inspection, cleaning, or future tie-ins.
