Heat exchangers are commonly used to transfer heat from steam, water, or gases, to gases, or liquids. Some of the criteria for selecting materials used for heat exchangers are corrosion resistance, strength, heat conduction, and cost. Corrosion resistance is frequently a difficult criterion to meet. Damage to heat exchangers is frequently difficult to avoid.
There are many variables related to specifying heat exchangers -- for example, temperatures, flow rates, pressure drop and heat transfer -- that are common to all types. There also are some variables that are specific to specifyin…
