In a shell and tube heat exchanger two fluids circulate in a different temperature conditions exchange heat through the walls of the tubes without direct contact between the fluids. The fluid flowing inside the heat transfer tubes that belongs to the tube bundle they finds the tube side of a shell and tube heat exchanger. On the contrary the fluid flowing inside the shell of the exchanger defines shell side of a shell and tube heat exchanger
Mechanical design of heat exchanger consists of designing various pressure and non-pressure components. The structural rigidity and adequate service of heat exchanger depends on the proper mechanical design. Mechanical design is commonly performed according to the design standards and codes. Following are some mechanical design standards and pressure design codes used in heat exchanger design are:
Mechanical Design
1. ASME Section VIII Div. 1
2. TEMA Codes
3. HEI Standards 4. API
