Titanium heat exchanger

- Jan 13, 2018 -

Titanium heat exchanger is a kind of high-quality titanium tube made of heat transfer part of the heat to the cold fluid heat transfer equipment. Titanium heat exchangers with many advantages of industrial pure titanium, chemical, petroleum, power, food and many other general industrial equipment, occupy an important position in the production.

In practical application, the heat exchange 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 often deposited on the heating surface, the precipitation of crystallization and the formation of scale layer, affecting heat transfer; some solute is heat-sensitive, high temperature residence time is too long and easy to degenerate; Some materials have greater corrosive Or higher viscosity and so on.

Physical properties


Titanium heat exchanger made of high quality titanium. In physical properties, titanium tube with light weight, superior mechanical properties and many other advantages. Titanium strength, pure titanium tensile strength up to 180kg / mm2. Some steels have a higher strength than titanium alloys, but the specific strength (tensile strength to density ratio) of titanium alloys exceeds that of high quality steels. In addition, titanium has good heat resistance, low temperature toughness and fracture toughness.
Titanium tube in accordance with the requirements and performance of different implementation of two national standards:
GB / T3624-1995 GB / T3625-1995.
Supply grades: TA0, TA1, TA2, TA9, TA10
BT1-00, BT1-0
Gr1, Gr2

Chemical properties

Chemically, titanium shows good stability and has good corrosion resistance in a wide range of industrial solutions. Pure titanium is an excellent refrigeration equipment parts materials.
Industrial titanium can be widely used in organic compounds, alkali solution, and salt solution and other media, and not easy to react with it, excellent corrosion resistance; pure titanium at low temperature hydrochloric acid, sulfuric acid, nitric acid and other inorganic acids have Good corrosion resistance; However, with the increase of medium concentration and working temperature, industrial pure titanium easily reacts with the above inorganic acid to reduce the corrosion resistance of titanium. Therefore, in the heat exchange process, the concentration of Operating temperature;
Industrial pure titanium at room temperature for formic acid, oxalic acid, lactic acid and other organic acids have good corrosion resistance.
