Instructions Place bottom plates in alphabetical order and weld bottom plate in numerical order.When aligning and tack welding No.2 seams,care should be taken to assure that Seam No.3 is aligned the entire length.This procedure is repeated across the tank bottom with Seams No.4 and 5,6 and 7,8 and 9,and 10 and 11.Preventing Leaks in Large Aboveground Storage TanksMost of the design effort associated with flat bottom tanks has been directed at the shell and roof (fixed and floating). Coatings are not used on the underside of tank bottoms because the welding process would destroy them.3 (d) 1 A complete discussion of this topic may be found in the book Aboveground Storage Tanks by Philip Myer and

API 650 Advance Tank Construction

API 650 is the standard governing welded tanks for oil storage.It dictates tank design,fabrication,welding,inspection,and erection requirements.API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oilAPI 650 ABOVEGROUND STORAGE TANKS,Part I Code Storage tanks are used as reservoirs to contain a sufficient reserve of any product for later use and or commercialization.Vertical cylindrical flat bottom tanks allow us to store large volumetric quantities at low cost,with the only limitation that they can only be used at atmospheric pressure or relatively small internal pressures.
