Why are the bolts used to install plate-fin heat exchangers arranged in alternating lengths?

I’m not an expert in equipment; I observed the installation of plate-fin heat exchangers and noticed that the bolts were installed alternately, with longer and shorter bolts, with the shorter ones being those on the edges. Some people say this is done to address thermal effects. Could someone please explain this in more detail? This post was last edited by abingchem on 2009-4-6 at 11:12

If it’s just for comparison, aren’t such long bolts a waste? It must be due to an issue with the device.
