Heat Exchangers are equipment used in several process industries for heating or cooling process fluids with hot or cool fluids respectively.
The primary type of heat exchanger offered by Sungov is shell and tube heat exchanger. Shell & tube-type heat exchangers achieve heating, cooling, condensing or evaporation of distinct fluid streams by transfer of thermal energy through conductive tube bundles enclosed in a shell. One fluid flows through the tubes and another between the shell and the tubes. The thermal energy is conducted across the tube walls from one fluid to the other. Baffles placed in the shell ensure improved heat transfer between the fluid streams.
Sungov offers thermal design as well as mechanical design for shell and tube heat exchangers. Thermal design is carried out using HTRI software and mechanical design using PV Elite software. The heat exchangers are designed to meet ASME Section VIII Division 1 and TEMA Classes as a minimum. Materials handled are carbon steel, low-temperature carbon steel and austenitic stainless steel. Other materials for construction may be possible.
The thermal efficiency of any shell and tube heat exchanger is dependent on the quality of the tube-to-tube sheet joints. All of Sungov’s tube-to-tube sheet weld procedures are qualified in accordance with ASME Section IX(mockup test).
Sungov’s shell and tube heat exchangers are generally used in oil & gas refineries, petrochemical plants and power generation plants.
