The shell-and-tube heat exchanger is used today to change the temperature of the working medium, which is in liquid or vapor form, while ensuring the complete safety of its aggregate state. The use of such equipment is carried out in various technological processes in the chemical, petrochemical, oil refining and gas industries.
Heat exchangers are often used when there are significant relative movements of pipes and casing, since in such equipment one of the grids is not connected to the casing and can be completely moved along the axis in the event of thermal elongations.
The shell-and-tube heat exchanger can withstand the pressure from the side of the refrigerant not more than 1 MPa, and in the intertubular space the pressure can reach already 2.5 MPa, which is their main feature in comparison with the standard options differing in the lower maximum permissible pressure.
Also, the originality of the design of this type of shell-and-tube heat exchanger is also in the fact that the pipe flaps inside the casing are fixedly fixed exclusively from one end of the device while the tube bundle is completely free from the opposite side. Due to such an original design, the risks of deformation of pipe assemblies are completely eliminated in the event of a sudden temperature drop of that medium, due to which heat exchange is ensured.
