Product/Project Description:
80 foot diameter x 32 foot high External Press-Broke Knuckle Roof tank. Close proximity to major fault lines in Southern California, this tank was engineered with a (3) column open center support structure and an external press-broke roof. With that combination, the roof is able to accept a 7 foot sloshing wave during a major seismic event without failure. In addition, the fully seal welded Press-Broke structure allows for ZERO inaccessible areas on the interior of the tank in the crucial vapor space, so opportunities for potential corrosion are dramatically decreased and this tank should see extended service life’s in between maintenance cycles.
