ASME SB111 Low Fin Tube

Product Description

ASME SB111 C70600, CuNi 90/10, Copper Nickel Seamless Tube Low Fin Tube For Heat Exchanger

Product Description

This is a low finned tube made from ASME SB111 C70600 (90/10 Copper-Nickel), commonly used in marine heat exchangers, condensers, and seawater-cooled systems. The low fins are integrally formed on the outside surface of the base tube, increasing the surface area and heat transfer efficiency without adding external material.

Chemical Composition of C70600 (CuNi 90/10)

Element	Content (%)
Copper (Cu)	88.6 min (including Ni)
Nickel (Ni)	9.0 – 11.0
Iron (Fe)	1.0 – 1.8
Manganese (Mn)	1.0 max
Zinc (Zn)	1.0 max
Lead (Pb)	0.05 max
Others (each)	0.05 max

Mechanical Properties of C70600 Tube

Property	Typical Value
Tensile Strength	≥ 310 MPa (45 ksi)
Yield Strength	≥ 105 MPa (15 ksi)
Elongation	≥ 30%
Hardness	≤ 100 HRB

Advantages C70600 Low Fin Tube Compared to Other Materials

Advantage	Description
1. Superior Seawater Corrosion Resistance	C70600 offers excellent resistance to seawater corrosion, outperforming carbon steel and aluminum, which are prone to rust and pitting in marine environments.
2. Excellent Biofouling Resistance	Copper-nickel naturally resists marine organism growth (e.g., barnacles and algae), reducing maintenance needs—something stainless steel and aluminum can't do without coatings.
3. High Thermal Conductivity	Better heat transfer performance than stainless steel, ensuring more efficient thermal exchange.
4. No Galvanic Corrosion with Fins	Because fins are integrated from the same base material (monometallic), there is no risk of galvanic corrosion—unlike carbon or stainless tubes with aluminum fins.
5. Strong Mechanical Integrity	Maintains ductility and toughness at elevated temperatures and pressures, especially compared to aluminum which is softer and less pressure-resistant.
6. Low Maintenance Requirements	Natural corrosion and biofouling resistance minimize inspection frequency and reduce downtime.
7. Long Service Life in Harsh Environments	Proven reliability in offshore, shipbuilding, and coastal power applications, where stainless steel may suffer from crevice corrosion.
8. Resistance to Stress Corrosion Cracking (SCC)	Better SCC resistance in chloride-rich environments compared to austenitic stainless steels like 304L or 316L.
9. Stable Heat Transfer Over Time	Fewer fouling and corrosion issues ensure consistent performance compared to carbon steel or aluminum fin tubes.

Applications

Marine condensers
Seawater-cooled heat exchangers
Desalination systems
Offshore platform coolers
Power plant condenser systems
Shipbuilding and naval systems
