C70600 CuNi 70/30 Pipe Copper Nickel Seamless Tube ASME SB111
C70600 CuNi 70/30 Pipe Copper Nickel Seamless Tube ASME SB111
1.Product Description
Copper-nickel pipe is a high-performance alloy tube primarily composed of copper with nickel as the main alloying element (typically 10% or 30% nickel). It also contains iron and manganese to enhance corrosion resistance and mechanical strength. Known for its excellent resistance to seawater biofouling and erosion, this pipe is the standard material for marine and offshore applications.
2.Product Functions
-
Fluid Transport: Conveys seawater, freshwater, oil, and non-oxidizing acids.
-
Heat Exchange: Efficiently transfers heat in condensers and coolers.
-
Pressure Management: Withstands moderate to high pressure (up to 5000 psi depending on schedule).
-
Action: Copper content naturally inhibits microbial growth inside the pipe.
3.Product Advantages
-
Superior Seawater Resistance: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking.
-
Biofouling Resistance: Naturally prevents marine organism growth, reducing maintenance.
-
Excellent Fabricability: Can be easily bent, flanged, and welded (TIG/MIG).
-
Thermal Conductivity: Better heat transfer than stainless steel.
-
Long Service Life: Up to 40+ years in aggressive marine environments.
