Foundations of aboveground steel tanks

The proposed construction is similar to the API Std.650,but the foundation ring is moved in the outside direction where it can not be influenced of the load of the shell and the tank roof upon it.When there is soil settlement under the tank,the reinforced concrete ring does not allow full drain of the water so that this solution is unfortunate.File Size 884KBPage Count 15Minimum Thicknesses Of Above Ground Storage Tank Plates Oct 07,2011 API 650 tanks Radius Versus Nominal Plate Thickness#0183;the minimum thicknesses of each part in above ground storage tank according to API 650 as followong - minimum thickness for first course in shell having inside diameter less than 60 m is 6 mm without corrosion allowance.- minimum thickness for annular plate of bottom plates is 10 mm with corrosion allowance.- it is not allowable - no way File Size 381KBPage Count 8People also askWhat is the maximum thickness of an API 650 tank?What is the maximum thickness of an API 650 tank?API 650 only covers tanks that support the whole bottom evenly and tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F.It requires that you have a minimum material thickness of 3/16 inch.Choosing Between API 620 and 650 for Your Storage Tank
