Study of Steel Silo Used for Material Storage

摘要

A silo of 40 ton capacity is designed, analyzed, fabricated and tested. The silo is designed based on ASME Sec VIII Div I, using PV elite software. The material used is SA 36 for fabrication of the silo. According to the design calculation required thickness of shell is 7mm, cone is 8mm, and top head is 8.8mm. The thickness of the material used is 10mm for shell, 12mm for cone and top head. Maximum allowable working pressure and Maximum Allowable Pressure (New and Cold) are calculated for the given thickness and are seen to be less than the working pressure. Actual stress at given pressure and thickness is also calculated with corrosion rate of 1.5.
