Understanding Heat Exchanger Reading 02

6. Equivalent Bolting Pressure is the pressure equivalent resulting from the
effects of bolting loads imposed on tubesheets in a fixed tubesheet heat
exchanger when the tubesheets are extended for bolting as flanged
connections.
7. Equivalent Differential Expansion Pressure is the pressure equivalent
resulting from the effect of tubesheet loadings in a fixed tubesheet heat
exchanger imposed by the restraint of differential thermal expansion
between shell and tubes.
8. Expanded Tube Joint is the tube-to-tubesheet joint achieved by
mechanical or explosive expansion of the tube into the tube hole in the
tubesheet.
9. Expansion Joint "J" Factor is the ratio of the spring rate of the expansion
joint to the sum of the axial spring rate of the shell and the spring rate of
the expansion joint.
