Tank Grades

Selection of the proper location on the lease for storage tanks is of prime importance. Technical Data used in the field explained in  petroleum courses in Rawalpindi. The location should provide good drainage and be on well-packed soil-not a fill-if possible. The tank foundation or grade should be slightly elevated, level, and somewhat larger in diameter than the tank itself. 

For steel tanks, either bolted or welded, the best grade is one made of small gravel. crushed rock, etc., held in place by steel bands. This type of grade allows no water to stand underneath the tank and provides air circulation. If the tank is to be set directly on the ground, felt tar paper should be applied to the grade first and the tank set on this. If concrete is used for the grade, it should be slightly larger in diameter than the tank and have shallow grooves on the surface to provide air circulation. Many codes. standards, and specifications regulate the location, design, and installation of storage tanks dependent on their end use. Selecting the proper specification and  providing adequate fire protection for  the installation may lower insurance rates over the life of the installation.

Firewalls or Dikes. Dikes are provided to contain the volume of a certain portion of the tanks enclosed depending on the tank contents. They are used to protect surrounding property from tank spills or fires. In general, the net volume of the enclosed diked area should be the volume of the largest tank enclosed (single-failure concept). The dike walls may be earth, steel, concrete, or solid masonry designed to be watertight with a full hydrostatic head behind them. Local codes and specifications may govern construction. If more than one tank is within the diked area, curbs or preferably drainage channels should be provided to subdivide the area to protect the adjacent tanks from possible spills.
