The main components of a heat exchanger are the front
head, shell section and rear head. Each component is available in a
number of varying standard designs.
Front and Rear Head Designs
Head designs can vary from plain standard castings to fabricated
assemblies with many special features. In many cases, the requirements
of an installation may dictate the choice of the more elaborate
design.
Shell Section Designs
Heat exchanger shells are manufactured in most standard sizes,
materials, and thickness. Small sizes are usually fabricated of
standard size pipe. Larger sizes are fabricated of plate.
Selection of a particular size shell depends, of
course, on the requirements of a given installation.
