Skirt-bearing-plate design

FIG. 21-4 Belt-conveyor loading details, (a) Typical skirt-plate design and dimensions, (b) Pad belt and special roller-bearing idlers for heavy-duty loading. (Stephens-Adamson Division, Allis-Chalmers Corporation.)... 

After the skirt and bearing plate have been designed, the skirt design should be cheeked for the rt action of the bolting chairs or ring. (See sefrtipn 10.1 g.)... 

Rolled-anole Beahimg Plate. If the vertical vessel is not very high and a skirt is used to support the vessel rather than le, lugs, or columns, a simple design may suffice for the bearing plate. If the calculated thickness of the bearing plate is in. or less, a st l angle rolled to lit the outside of the skirt may he lap welded as shown in Fig. 10.3. 

Bp = Allowable bearing pressure, PSI Do = OD of vessel shell, in Dsk = OD of skirt at base plate, in E = Modulus of elastidly, PSI Fc = Allowable compressive stress, PSI f = Load at support points. Lbs fp = Bearing pressure, PSI Ft = Allowable sttess, tension, PSI Fy = Minimum specified yield strength of skirt at design temperature, PSI...
