Depend upon material of construction...
If SS u can use HCl but immedeatly wash it by NaOH and clean cold water.
It is difficult from cleaning point of view. Both end chambers have to be removed so as to clean the heat exchanger with odd nos of passes. Thanks & Regards Priyanka Karkera
The factors that are affected by number of tubes in shell and tube heat exchanger is the rate of heat transfer and flow rate.
the most effective way to do so is to reduce the flow of the heat exchanger
about 10% of the total number of tubes
increase to heat transfer coefficent

It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.

allow for tube expansion

shell and tube heat exchangers are used mostly in the chemical processing industry for heating, cooling, condensing, and evaporating highly corrosive liquids and gases. AMETEK Fluoropolymer Product shell and tube heat exchanger was the first heat exchanger developed using fluoropolymer tubes and the patented honeycomb tube to tube sheet joint which has been successfully used for over 55 years. Sulfuric Acid is the chemical most used with Ametek Fpp heat exchangers. The process of making sulfuric acid can vary, but any company dealing with the manufacturing process has a high potential for the use of a fluoropolymer heat exchanger in their process. Other Acids commonly requiring fluoropolymer heat exchangers are Hydrochloric, Nitric and Hydrofluoric Acids. Another chemical manufacturing industry fluoropolymer heat exchangers are used in is the Chlor-Alkali manufacturing process.
The assumption to design heat exchanger is that it must be a shell and tube device. This device must allow the transfer of heat from one fluid to another without mixing the two fluids.
