Is seawater used as the medium for the condenser tube material B10?
Thread Content
Experts, is the material BFe10-1-1 used for air conditioner condenser tubes suitable for seawater environments? What is the level of corrosion associated with it? Does anyone know anything about this? Thank you!
B10 is an excellent copper-nickel alloy resistant to seawater corrosion. Corrosion resistance mechanism: A nickel- and iron-rich protective film is formed on the surface. However, the following points need to be controlled: 1. Moving seawater generates shear stress on the surface; the higher the flow velocity, the greater the shear stress. When this shear stress reaches a certain level, it damages the protective film and causes the alloy material to corrode. Therefore, there is a critical value for flow velocity, and this value must be controlled ； 2. Erosion effects: Factors such as the oxygen content, sand content, and temperature of seawater; erosion can damage the protective film ； 3. Factors affecting the integrity of the protective film: Influence of material surface roughness. Protection measures: 1. Control the seawater flow rate ； 2. Control the impurity content in seawater ； 3. Passivate the material surface.
It also depends on the quality of the seawater.
It’s air conditioning in the same sea area, so the seawater should be the same. Those with spikes have a higher cooling capacity.
