The advantage of copper nickel alloy condenser pipe used in ship industry

Heat exchanger and condenser in power plants, chemical plants, petrochemical equipment, and plays a significant role in many fields such as pharmaceutical, food machinery, one of the important equipment which is the important component of heat exchange tube and condensation tube, it directly affects the service life of the unit, Ann, efficiency, heat exchanger and the number of condenser tube is very much, the cost of heat exchanger and the condenser of the cost of 60% 80%, therefore, selects the high ratio of performance and condensation tube heat exchange tube of metal materials, is the crucial one annulus.TitaniumCn
The material, and heat exchange tube condenser pipe shall have excellent heat transfer performance, more want to have good resistance to corrosion, erosion and abrasion resistance, also should have good strength and rigidity and good plasticity, easy processing and manufacturing.
Nickel copper alloy condenser pipe, it is a kind of tubing used in cooling equipment, water cooling system is mainly used in ships.First is to use tin brass, then add the arsenic, so as to improve the quality of the condenser pipe and life.If add Mn, Ni, and trace rare earth elements, can further improve on the strength and corrosion resistance.At present, the main is to use and BF10 BFe30-1-1-1-1.
That compared with titanium, stainless steel material, what is the difference between the three?
(1) titanium
In the future, may use titanium instead of copper and nickel alloys, as the material of ships to the condenser.Because big place in sea water flow, if you use the monel alloy, because its price is too high, so the use value is not high.The use of copper and nickel alloy material, although it is commonly used materials, but cannot be used for a long time, life is limited, so need to be replaced on a regular basis.And titanium, it will not be in all concentrations of sulfide corrosion, so the seawater containing sulfide has good corrosion resistance, service life is longer.
In addition, the heat conduction performance of the titanium is poorer, but by the method of using thin-wall titanium tube can be improved.But overall, titanium condenser pipe compared with nickel copper alloy condenser pipe, there are still some problems.The production and processing of titanium is difficult, production is not high also, and expensive, so the price is not dominant.
(2) stainless steel
It is hard to become the condenser pipe material, because its thermal conductivity for only 38% of copper and nickel alloy, while the corrosion rate and corrosion rate is better than that of copper and nickel alloy, but to solve a problem, that is the problem of biofouling prevention, if you can't solve this problem well, so will affect the use effect.
