The required heat duty, film coefficients, conductivity, etc. for a shelland-tube heat exchanger can be calculated using the procedures in Heat Transfer Theory, Approximate U-values…

TEMA standards provide for two classes of shell and tube exchanger qualities. Class C is the less stringent and is typically used in onshore applications…
The question always comes up of which fluid to put in the tubes and which fluid to put in the shell. Consider placing a fluid…
In selecting an exchanger, one must know the advantages and disadvantages of each type. The three basic types of shell-and-tube exchangers are fixed tube sheet,…
In addition to the type description code there is also a shorthand that is used for classifying heat exchangers. The first element of the shorthand…
There are many different arrangements of the shells, tubes and baffles in heat exchangers. Figure 3-6 is a list of TEMA standard classifications for heat…
Shells up to 24-in. OD are fabricated from pipe using standard pipe nominal diameters. Standard pipe diameters and wall thicknesses are given in Volume 1,…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
Heat-exchanger tubes should not be confused with steel pipe or other types of pipe that are extruded to steel pipe sizes. The outside diameter of…
Shell-and-tube exchangers contain several types of baffles to help direct the flow of both tube-side and shell-side fluids. Pass partition baffles force the fluid to…
