Titanium Heat Exchanger is a kind of heat exchanger equipment made of high quality titanium tubes to transfer part of the heat from hot fluid to cold fluid. With the many advantages of industrial pure titanium, titanium heat exchanger is the general equipment for chemical, petroleum, power, food and many other industrial sectors, and occupies an important position in the production.
1, the nature of the material
In practice, the heat transfer effect of the heat exchanger has a great relationship with the material and process characteristics of the heat exchanger. Materials in the concentration process, solutes or impurities are often deposited on the heating surface, precipitation crystallization and the formation of scale layer, affecting heat transfer; some solutes are heat-sensitive, stay at high temperatures for a long time is easy to deteriorate; some materials have a large corrosive or high viscosity and so on. Physical properties: titanium heat exchanger is made of high quality titanium tubes. In physical properties, Titanium Tube has a light weight, superior mechanical properties and many other advantages. Titanium strength, pure titanium tensile strength of up to 180kg/mm2. some steel strength than Titanium Alloy, but the specific strength of titanium alloy (tensile strength and density ratio) is more than high quality steel. In addition, titanium alloy has good heat-resistant strength, low temperature toughness and fracture toughness.
Chemical properties: in chemical properties, titanium shows good stability, in a variety of industrial solutions have good corrosion resistance. Industrial pure titanium is excellent material for refrigeration equipment parts. Industrial pure titanium can be widely used in organic compounds, alkali solutions, and salt solutions and other media, and it is not easy to react with, excellent corrosion resistance; pure titanium at room temperature for low concentrations of hydrochloric acid, sulfuric acid, nitric acid and other inorganic acids have good corrosion resistance; but with the increase in the concentration of the medium as well as the working temperature of the industrial titanium is easy to chemical reaction with the above inorganic acids, making the titanium corrosion resistance is reduced, therefore, in the Heat transfer process should pay attention to the concentration of the medium and the working temperature; industrial titanium at room temperature on the formic acid, oxalic acid, lactic acid and other organic acids have good corrosion resistance.
2, titanium heat exchanger characteristics
Titanium heat exchanger due to metal ions are not easy to lose, so you can take full advantage of this non-magnetic characteristics, used as a heat exchanger for pharmaceutical and food applications. Because of titanium's strong corrosion resistance, so the service life of the heat exchanger is long, and less maintenance costs in use. In addition, because of its small size, heat transfer capacity and other advantages, related equipment (such as pumps) investment and operating costs can be reduced accordingly.
3、Application scope
Titanium heat exchanger with industrial pure titanium's various excellent properties, widely used in various types of seafood farming, seawater heat transfer, salt water heat transfer, chemical industry, food, medicine, metallurgy, refrigeration, light industry, electroplating industry, aluminum oxidation tanks, salt, papermaking, ultrasonic, electronic communications, centralized heat supply and other industries and fields.
