Heat Exchanger Shell & Tube
The principle of operation is simple enough: Two fluids of different temperatures are brought into close contact but they are not mixing with each other.
One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids.
Accounted for 85% of new exchangers supplied to oil-refining, chemical, petrochemical and power companies. Why?
•Can be designed for almost any duty with a very wide range of temperatures and pressures
•Can be built in many materials
•Repair can be by non-specialists
•Design methods and mechanical codes have been established from many years of experience
