Titanium heat exchangers FROM OPEKS ENERGOSYSTEM

Heat exchangers are called heat engineering devices for industrial, economic or domestic purposes, with the help of which heat exchange (heat transfer) is organized between two moving media (liquid or gas) pumped through closed pipeline systems. Depending on the intended purpose, heat exchangers can work with a wide variety of liquid and gaseous media, sometimes with very high chemical (corrosive) activity. Therefore, to ensure work with chemically active media, the surfaces (parts) of heat exchangers in contact with them are often made of chemically passive (corrosion-resistant) materials.

Titanium as a structural material for heat exchange equipment

Among the materials available in mechanical engineering, titanium (Ti) is one of the best for use in the structures of corrosion-resistant heat exchange equipment - a light (atomic mass 47.87) strong silver-yellowish metal, relatively refractory. In mechanical engineering, titanium is usually used as a base for a variety of structural titanium alloys (as well as iron Fe - for cast irons and steels), which are characterized by:

  1. High chemical passivity, resulting in excellent corrosion resistance. Titanium, even working at high temperatures, up to 600-800 degrees C, practically does not react with oxygen, water and water vapor, salts, chlorine, glycols (alcohols), freons, phenols. It is also quite stable against saline solutions, unsaturated acidic and alkaline solutions, except for solutions of HF, H 3 PO 4 , H 2 SO 4, and concentrated alkalis, acids.
  2. Sufficiently high temperature resistance. Titanium already belongs to the category of refractory metals, its melting point is 1668 degrees C (according to other sources - 1940 degrees C).
  3. Relative structural lightness: Ti is about twice as light as Fe (in the form of cast iron or steel), but also about twice as heavy as aluminum.
  4. Good structural strength (hardness and elasticity), which is at least not lower than the corresponding steel grades, and allows the use of titanium blanks in rolling and stamping production, for the manufacture of titanium heat exchange tubes and heat exchange plates.

Combining high corrosion resistance, mechanical strength and temperature resistance, titanium (among structural metals) is one of the best structural materials, in terms of its complex of characteristics it significantly surpasses: aluminum and its alloys, copper and its alloys (primarily brass), and even highly alloyed ( stainless) steels. That is why it received the widest application not only in industry and mechanical engineering, but even in such a specific area as medical prosthetics.

With what coolants and in what areas is it advisable to use titanium heat exchangers

Titanium shell-and-tube and plate heat exchangers can work with a wide range of corrosive heat transfer fluids, under conditions of high operating temperatures and pressures, which are quite common in industry, household and household spheres. But titanium heat exchangers show some of the best technical and economic indicators (in terms of price / quality ratio) when working with aqueous solutions of salts, chlorine and fluorine, typical for such working environments as:

  • salty sea water;
  • prepared, sanitized (chlorinated and (or) fluorinated) fresh water;
  • saturated salt solutions in industrial technological processes;
  • superheated water and hot steam.

The main areas of application for titanium heat exchangers include:

  • ship power plants, onshore power or industrial facilities using outboard salt (sea) water for cooling;
  • industrial and industrial heat and power facilities (reactors, turbines, boilers), cooling systems for metallurgical furnaces operating with large volumes of untreated water, under conditions of high operating temperatures and pressures;
  • chemical industry enterprises;
  • heating systems for specially prepared (chlorinated and fluorinated) water in swimming pools.

Parameters for the selection of a titanium heat exchanger

The determining parameter for choosing a titanium heat exchanger is the chemical composition (aggressiveness) of the working media, their concentration and the level of operating temperatures. Which, at certain values, directly indicate the need to use corrosion-resistant and temperature-resistant titanium as a structural material.

The heat engineering parameters for selecting a titanium heat exchanger are absolutely the same as for a steel one:

  • required thermal power;
  • the required indicator of the mass flow rate of heat carriers;
  • working temperatures of working media at the inlet and outlet of the heat exchanger, as well as their maximum allowable temperature;
  • working and maximum allowable pressure of working media;
  • own hydraulic resistance of the heat exchanger (maximum permissible pressure loss);
  • special requirements for the dimensions of the installation (if any);
  • requirements for the nature of the connection to the heat engineering system (bore diameters of the nozzles, fastening system - flange, sleeve, for welding).

If necessary, experienced heat engineering engineers of OPEKSEnergosystems will provide qualified assistance in selecting a titanium heat exchanger for the operating conditions of a specific heat engineering system. Титановые теплообменники
