ASME B16.5 CuNi 70/30 Forged Flange, Class 150 Socket Weld, Marine Grade SWRF
1.Product Description
The Copper Nickel Socket Weld Flange is manufactured from high-quality 70/30 Copper Nickel Alloy (CuNi 70/30, UNS C71500) in compliance with ASME B16.5 standard. This forged flange features a Class 150 pressure rating and socket weld connection type. The socket weld design allows the pipe to be inserted into a recessed area of the flange and welded around the outer diameter, creating a strong, leak-proof permanent connection ideal for high-pressure systems . The 70/30 copper-nickel alloy consists of 70% copper and 30% nickel, with trace amounts of iron and manganese, providing excellent mechanical properties and corrosion resistance
.
2. Applications
Due to the alloy's exceptional resistance to seawater corrosion and biofouling, CuNi 70/30 flanges are widely used in :
-
Marine & Offshore Engineering: Seawater cooling systems, shipbuilding, desalination plants, offshore platforms
-
Petrochemical Industry: Chemical processing, heat exchangers, pressure vessels
-
Power Generation: Nuclear and thermal power plant cooling systems
-
Naval Applications: Naval ship piping systems (DEF STAN 02-879 compliant)
-
Industrial Applications: Hydraulic pipelines, firewater systems, fish farming cages
3. Product Functions
The Copper Nickel Socket Weld Flange serves the following functions in piping systems:
-
Pipe Connection: Provides a reliable, leak-proof connection between pipes, valves, pumps, and other equipment
-
System Access Point: Allows for easy disassembly and maintenance of piping systems
-
Pressure Containment: Safely contains system pressure up to Class 150 rating
-
Flow Direction Control: Facilitates changes in piping direction when used with elbows or tees
-
Equipment Isolation: When used with blind flanges, can isolate sections of the piping system
