On the steel boat,this is more often based on the practical minimum necessary to ward off corrosion over time,provide decent welds,and a thickness adequate to minimize unsightly deformation.Thus 10GA (.1345) plating is commonly specified as a minimum in small steel boats even if something thinner might suffice if strength alone were the Part VII Anchor Bolt Chairs W - ApiexamWhere base or bottom plate is not welded to shell in the shop,as for flat-bottom tanks and single.pedestal tanks,.shop attach side plate.s to top plates and then ship the assembly for field installation.When you do this,weld both sides at top of side plates-so shrinkage will not pull side plate out ofPROCESS FABRICATORS LUu)Vertical Storage Tanks Flat Bottom Builtfor storage of liquid products in bulk.Our flat bottom,cone roof tanks are ex- tremely durable and exceed U.L.Stan- dard 142 in strength,corrosion resistance,and appearance.Costly footings and pier forming are eliminated; only a con- crete slab or compacted aggregate base is required.

In the absence of restraint,angular distortion in both fillet and butt joints will be a function of the joint geometry,weld size and the number of runs for a given cross section.Angular distortion (measured in degrees) as a function of the number of runs for a 10mm leg length fillet weld is shown in Fig.4.D100-96 Welded Steel Tanks for Water StorageTypical Unanchored Flat-Bottom Tanks ..72 6 Diagram for Checking Overturning of Cross-Braced Elevated Tanks (Seismic) ..75 7 Seismic Zone Map of the United States and Puerto Rico for Seismic Design of Water Storage Tanks .75 8 Curve for Obtaining Factor Kp forContents18 Minimum Size of Fillet Weld Shell-to-Bottom Joint ..71 19 Minimum Diameter for Unrolled Shell Plates for Elevated Tanks..75 20 Maximum Thickness of Reinforcement for Butt Joints..77 21 RoundnessCylindrical Shells..80 22 Maximum Allowable Offset of Aligned Butt Joints..
