Titanium alloy heat exchanger as one of the most important production devices on the chemical production line, its excellent performance is widely loved by people, so compared with other metal heat exchanger, titanium alloy heat exchanger advantages embodied in what aspects? Let's discuss it specifically.
Here is the content list:
The physical properties of titanium
The characteristics of titanium alloy
The advantages of the titanium alloy heat exchanger
To understand titanium alloy, we must first understand the characteristics of titanium. The density of titanium metal is 4.51g/cm3, higher than aluminum and lower than steel, copper, nickel, its strength is located in the first metal. Titanium is a very active metal, its equilibrium potential is very low, in the medium of thermodynamic corrosion tendency is large. But in fact, titanium in many media is very stable, such as titanium in oxidizing, neutral and weakly reducing media is resistant to corrosion. This is because titanium and oxygen have great affinity, in the air or oxygen-containing media, titanium surface to generate a layer of dense, strong adhesion, inert oxide film, protecting the titanium substrate from corrosion. Even due to mechanical wear will quickly self-heal or regenerate. This shows that titanium is a metal with a strong tendency to passivate. The oxide film of titanium always maintains this property at media temperatures below 315°C. In order to improve the corrosion resistance of titanium, surface treatment technologies such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation, and laser treatment have been studied to enhance the protective effect of the oxide film of titanium and obtain the desired corrosion resistance.
In response to the need for metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solutions, high-temperature wet chlorine, and high-temperature chlorides, we have developed a series of corrosion-resistant titanium alloys such as titanium-molybdenum, titanium-palladium, and titanium-molybdenum-nickel. Titanium castings using titanium - 32 molybdenum alloy, titanium - 0.3 molybdenum - 0.8 nickel alloy, or titanium equipment, the local use of titanium - 0.2 palladium alloy, are obtained very good results. Good heat resistance The new titanium alloy can be used at 600℃ or higher for a long time. Good low-temperature resistance Titanium alloy TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), and Ti-2.5Zr-1.5Mo and other low-temperature titanium alloys, its strength increases with the decrease in temperature, but the plasticity change is not large. From -196 ℃ to -253 ℃ low temperature to maintain good ductility and toughness, to avoid the metal cold brittleness, is the ideal material for low-temperature containers, storage tanks, and other equipment.
Titanium alloy heat exchanger can be used as a heat exchanger for pharmaceutical and food applications because metal ions are not easily lost, so it can make full use of this non-magnetic feature. Because of the strong corrosion resistance of titanium, titanium alloy heat exchanger has a long service life and low maintenance costs in use. In addition, because it has the advantages of small size and large heat transfer capacity, the investment and operating costs of related equipment (such as pumps) can be reduced accordingly.
