Shell-and-tube heat exchangers

Shell-and-tube heat exchangers are intended for use at power facilities, housing and communal services, and other industries for heating or cooling drinking, technical, chemically cleaned water, condensate, chemical reagents, other fluids with different physical characteristics.

Advantages of shell-and-tube heat exchangers:

• High thermal efficiency
• Small size and weight
• Low hydraulic resistance
• Increased reliability

Versatility in various conditions and with various mediums.

The technical characteristics of shell-and-tube heat exchangers determine their scope and reliability of operation. At the same time, they require correct calculation and quality manufacturing.

Correctly selected shell-and-tube heat exchangers represent the key to quality and long-term operation. If the shell-and-tube heat exchanger is not suitable for specific tasks (for example, the temperature of the pipes and the casing differs by more than five hundred degrees), deformation occurs, the results of which are quite deplorable: the functioning of heat carriers worsens, the heat exchanger breaks down, and the density of pipes and tube grids is disrupted.

Separate attention should be paid to the fact that shell-and-tube heat exchangers, the types of which practically do not differ, are high-tech, complex equipment, the most important elements of which are the tube bundles firmly connected by special gratings

Shell-and-tube heat exchanger is the most common, used in almost all industries.
