Material properties
In practice, the heat transfer effect of the heat exchanger and the heat exchanger material and process characteristics have a great relationship. 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 is higher than
Titanium Alloy, but the specific strength of titanium alloy (tensile strength and density ratio) is more than high quality steel. In addition, titanium alloys have good heat-resistant strength, low temperature toughness and fracture toughness .
Chemical Properties
In terms of chemical properties, titanium shows good stability and good corrosion resistance in a variety of industrial solutions. Industrial pure titanium is an 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 is not easy to react with, excellent corrosion resistance; pure titanium at room temperature on the low concentration of hydrochloric acid, sulfuric acid, nitric acid and other inorganic acids have a 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, the heat exchange process should pay attention to the medium of Therefore, in the heat transfer process should pay attention to the concentration of the medium and the working temperature.
Industrial titanium has good corrosion resistance to organic acids such as formic acid, oxalic acid and lactic acid at room temperature.
Titanium Heat Exchanger Features
Titanium heat exchangers are used as heat exchangers for pharmaceuticals and foodstuffs because the metal ions are not easily lost, making full use of this non-magnetic feature. Because titanium has a strong corrosion resistance, the service life of the heat exchanger is long and the maintenance cost is low. 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.
Scope of application
Titanium heat exchanger by virtue of 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 production, papermaking, ultrasonic, electronic communications, centralized heat supply and other industries and fields.
