Vertical Vessel Support Legs
Support legs can be made of wide-flange or pipe members. They are designed to resist axial loads, overturning moments, and lateral shear forces in the vessel. The attachment point to the vessel may cause high concentrated shell stresses which must be investigated by a qualified vessel designer. The allowable stress in the member may also be reduced because of high temperatures and the efficiency of the weld between the leg and the shell. The design of this joint is beyond the scope of this manual, and should be handled by an engineer familiar with this subject.
