Every type of storage tank TC offers has its application. The shop-welded tanks shown are custom fabricated in the shop and shipped to the field as one piece construction. When they arrive, they can be picked with a crane and immediately set into place or staged for installation at a later date.
When shop-welded tanks are utilized, field installation timeframes can be greatly reduced. The only negative in utilizing shop welded tanks are the limitations of capacity. Typically, these units are limited to a maximum capacity of ~8500 cubic feet of storage, as a one piece unit.
