Heat Exchanger Titanium
Material properties of Heat Exchanger Titanium
In practice, the heat transfer effect of the heat exchanger is closely related to the material and process characteristics of the heat exchanger. In the process of concentration, solute or impurity often deposit and crystallize on the heating surface to form scale layer, which affects heat transfer. Some solutes are thermally sensitive and perishable if they stay too long at high temperatures. Some materials have higher corrosive or higher viscosity and so on.
Titanium heat exchanger is made of high-quality titanium tube. In physical properties, titanium tube has the advantages of light weight, superior mechanical properties and so on. The tensile strength of pure titanium is 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 alloy has good heat resistance, low temperature toughness and fracture toughness .
Chemically, titanium exhibits good stability and corrosion resistance in various industrial solutions. Industrial pure titanium is an excellent accessory material for refrigeration equipment.
Industrial pure titanium can be widely used in organic compounds, alkali solution, salt solution and other media, and is not easy to react with it, good corrosion resistance; Pure titanium has good corrosion resistance to low concentration of hydrochloric acid, sulfuric acid, nitric acid and other inorganic acids at room temperature. However, with the increase of medium concentration and working temperature, industrial pure titanium is easy to react with the above-mentioned inorganic acid, which makes the corrosion resistance of titanium lower. Therefore, the concentration of medium and working temperature should be paid attention to in the heat transfer process.
Industrial Heat Exchanger Titanium has good corrosion resistance to formic acid, oxalic acid, lactic acid and other organic acids at room temperature.
