General Storage Tanks ^[*]

TecTank SealWeld tanks (see Fig. T-1) from Engineered Storage Products Company are designed for simple precision assembly. The critical flange-to-shell fabrication process incorporates positioning clamps and automated welding. Dual weld seams are used to increase the joint strength and to avoid warpage and distortion. During jobsite panel fit-up, flange connections are secured with structural bolts, not rivets. (See Fig. T-2.)

Figure T-2: Panels are butted together and secured with bolted fasteners on the exterior of the silo. Exterior aluminum structural flanges are in (13 mm) thick and smooth with no ribs or grooves to retain debris. (Source: Peabody TecTank.)

The interior welding of the assembled silo can proceed without the problems that plague traditional field-welded silos. Location costs are reduced, and the welding can be accomplished under controlled conditions. The welded interior of the product zone is free of ledges and gaskets.

Carefully controlled tank coating processes ensure the product within the tanks is not contaminated. Some examples of products stored are:

• ABS Pellets

• Alfalfa (Dehydrated)

• Alumina Ore

• Ammonium Nitrate

• Barium...
