A shell and tube heat exchanger is a type of heat transfer equipment consisting of:

A cylindrical outer shell

A bundle of internal tubes

Inlet and outlet nozzles

Internal baffles and support components

One fluid flows through the tubes while another fluid flows around the tubes inside the shell. Heat transfers through the tube walls without the fluids mixing together.

This design provides:

Efficient thermal transfer

Excellent mechanical strength

Easy maintenance

Adaptability to various industrial processes

Shell and tube heat exchangers are commonly designed according to TEMA and ASME standards for industrial safety and performance.
