Storage Tank Types. Vertical tank (bolted and welded) (double wall and single wall) Open top tank (atmospheric) - Normally for petroleum products but can contain cooling water and fire water. Fixed roof tank (atmospheric, low pressure, high pressure) - Either be self supported or rafter/trusses supported depending on size. Repair of Tank Bottoms in Atmospheric Storage TanksAPI 653 restricts welding in the critical zone when making repairs to a portion of the tank bottom . The critical zone is defined as within the annular plate ring, within 12 inches of tank bottom reinforcement plate steel oil tank Lecture 15C.1 Design of Tanks for the - UL FGGFor petroleum storage tanks, steel bottom plates are specified, laid and fully supported on a prepared foundation. The steel plates are directly supported on a bitumen-sand layer on top of a foundation, usually of compacted fill or, if the subsoil is weak, possibly a reinforced concrete raft.
Large storage tank is one of the indispensable equipment in petrochemical plant. The tank bottom plate bears more force than other parts of the whole storage tank, while the serious welding deformation of tank bottom can reduce the loading capacity and stability of storage tank. The storage tank bottom is welded by a plurality of bottom plate and annular plate, the quantity of welding seam is much, the Grade Level Manways - Highland TankGrade Level Manways. Designed to AASHTO H20 requirements, each manway is constructed of A36 steel plate from 10 ga. to 1/4 thick with lids of 3/8 reinforced checkered steel plate .
