Titanium heat exchanger is a kind of heat transfer equipment which is made of high quality titanium tube and transfers part of heat of hot fluid to cold fluid. Titanium heat exchanger with many advantages of industrial pure titanium, chemical, petroleum, power, food and many other industrial sectors of the general equipment, in the production of an important position.
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.
Titanium pipe shall be subject to two national standards according to the different requirements and performance:
Supply brands: TA0, TA1, TA2, TA9, TA10
Specification: diameter of 4~114mm
Wall thickness delta 0.2 ~ 4.5 mm
Length within 15m
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, thus reducing the corrosion resistance of titanium. Therefore, the concentration of medium and working temperature should be paid attention to in the heat transfer process.
Industrial pure titanium has good corrosion resistance to formic acid, oxalic acid, lactic acid and other organic acids at room temperature.
Characteristics of titanium heat exchanger:
Titanium heat exchanger is not easy to lose metal ions, so it can make full use of this non-magnetic characteristics, used for pharmaceutical and food and other purposes of heat exchanger. Due to the strong corrosion resistance of titanium, so the device heat exchanger long service life, and in use maintenance cost is also less. In addition, due to its small size, large heat transfer capacity and other advantages, related equipment (such as pumps) investment and operating costs can be reduced accordingly.
Range of application:
Titanium heat exchanger with various excellent properties of industrial pure titanium, widely used in various seafood culture, seawater heat transfer, brine heat transfer, chemical industry, food, medicine, metallurgy, refrigeration, light industry, electroplating industry, aluminum oxidation tank, salt production, paper making, ultrasonic, electronic communication, central heating and other industries and fields.
