The titanium heat exchanger is a heat exchange device made of high-quality titanium tubes that transfers part of the heat of the hot fluid to the cold fluid.
First of all, let’s take a look at the metal “titanium and titanium alloy”: the density of metal titanium is 4.51g/cm3, which is higher than aluminum and lower than steel, copper, and nickel, but its specific strength ranks first among metals. Corrosion resistance Titanium is a very active metal, its equilibrium potential is very low, and the thermodynamic corrosion tendency in the medium is large. But in fact, titanium is very stable in many media. For example, titanium is corrosion-resistant in oxidizing, neutral and weakly reducing media. This is because titanium and oxygen have a great affinity. In the air or in an oxygen-containing medium, a dense, strong adhesion and inert oxide film is formed on the surface of titanium, which protects the titanium matrix from corrosion. Even due to mechanical wear, it will quickly heal itself or regenerate.
This indicates that titanium is a metal with a strong tendency to passivation.
The titanium heat exchanger is made of high-quality titanium tubes. In terms of physical properties, titanium tubes have many advantages such as light weight and superior mechanical properties. Titanium is strong, and the tensile strength of pure titanium can reach up to 180kg/mm2. Some steels are stronger than titanium alloys, but the specific strength (the ratio of tensile strength to density) of titanium alloys exceeds that of high-quality steels. In addition, titanium alloys have good heat resistance, low temperature toughness and fracture toughness.
