Lets Dive in a bit further

Now that we have learn the basic of Shell and Tube Heat Exchangers, it components, understanding UTS, YS and Allowable Strength, up until calculating Shell thickness, we are going to dive a little bit more into calculations;

Lets calculate Shell and Tube Heat Exchangers channel head thickness. Where exactly is the Channel Headers? Check Part 2 - The basics of Shell and Tube HEX.

Or check out part of a Shell and Tube HEX (U-Tube) below;

Now lets calculate the minimum thickness Tmin of the ellips head 2:1 [do not be intimidated by its name]

Refer ASME VIII Div 1 Appendix 1, the formula is;

T_min = (P_dt d_s K) / (2SE - 0.2P_dt)

P_dt = Design Pressure Tube side = 43 bar = 4.3MPa

d_s = ID = 1140 (refer previous data)

K = Check D/2h = 2

S = Allowable Stress = 148 MPa

E = 1

Plug it In [I will let you do the fun part]

Tmin = 16.6 mm

Tselect = tmin + C = 16.6 + 3 = 19.6 [Take 20mm]

Tselect = 24 mm
