Understanding Heat Exchanger Reading 02

DEFINITIONS
1. Baffle is a device to direct the shell side fluid across the tubes for
optimum heat transfer.
2. Baffle and Support Plate Tube Hole Clearance is the diametral difference
between the nominal tube OD and the nominal tube hole diameter in the
baffle or support plate.
3. Consequential Damages are indirect liabilities lying outside the heat
exchanger manufacturer's stated equipment warranty obligations.
4. Double Tubesheet Construction is a type of construction in which two (2)
spaced tubesheets or equivalent are employed in lieu of the single
tubesheet at one or both ends of the heat exchanger.
5. Effective Shell and Tube Side Design Pressures are the resultant load
values expressed as uniform pressures used in the determination of
tubesheet thickness for fixed tubesheet heat exchangers and are
functions of the shell side design pressure, the tube side design pressure,
the equivalent differential expansion pressure and the equivalent bolting
pressure.
