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.
Frequently Asked Questions
Q 1. What is a shell and tube heat exchanger?
A shell and tube heat exchanger is an industrial device used to transfer heat between two fluids—one flowing through tubes and the other around them inside a shell. Its design makes it ideal for high-pressure and high-temperature applications in oil & gas, chemical, and power industries.
Q 2. How does a shell and tube exchanger work?
In a shell and tube exchanger, one fluid passes through the internal tubes while another fluid flows over the tube bundle in the outer shell. Heat transfers between the two fluids through tube walls, enabling efficient thermal exchange without mixing the fluids.
Q 3. What factors are considered in shell and tube heat exchanger design?
A robust shell and tube heat exchanger design accounts for fluid flow rates, temperatures, pressure limits, material compatibility, heat transfer area, and fouling resistance. Proper design ensures optimal performance, long service life, and energy efficiency.
Q 4. Why should I choose industrial heat exchanger manufacturers for custom solutions?
Leading industrial heat exchanger manufacturers provide tailored solutions that meet specific process requirements, including custom tube layouts, materials (e.g., stainless steel), and compliance with industry standards. This ensures reliable performance and easier maintenance.
Q 5. What is the difference between a shell and tube heat exchanger and a tube type heat exchanger?
A shell and tube heat exchanger refers to the full assembly of shell, tubes, baffles, and headers, while a tube type heat exchanger typically emphasizes the tubular elements. In most industrial settings, both terms are used interchangeably, but shell designs include additional components for enhanced heat transfer control.
