Tube-to-tubesheet joints - ASME (mechanical) Code Issues

Jul 25, 2005 · Strength welds are often mandated when the design is for fixed tube sheets, stayed by the tubes. Tube sheets are relatively thin and flex with tube expansion, resulting in high shear loads at the tube to tubesheet interface. It is even more important to strength weld these joints when thermal/pressure cycling is anticipated.
