Advantages of shell and tube heat exchangers

1.They can be easily used for high pressure services where plate and frame heat exchangers cannot be used easily.

2.They are quite less expensive to the plate type heat exchangers.

3.The pressure drop across shell and tube heat exchangers are quite less than plate and frame heat  exchangers.

4.The tube leaks in the shell and tube heat exchangers can be easily located due to very appropriate and well develop methods.
