Hello,I have to design a storage tank using the ASME code with pressure=30psi ,diam=6.3 meter and the bottom have to be flat supported on the ground.Using the formula for flat covers in the ASME,the thickness is 3.75.Is this thick usual for tanks of this dimensions or is too much?Experts in tank foundations and bottoms analyze designs He described a Kinder Morgan facility built in 1987 with 40 tanks and said there have been zero tank-bottom failures due to corrosion.All tank inspections have shown zero observed corrosion in 15-20 years.All tank bottoms still have a nominal 0.248 to 0.255 remaining.Elliptical heads per API 650 - ast-forumJul 25,2005 A106 grade B ground supported flat bottom tanks#0183;The problem is that API-650 doesn't cover suspended-bottom tanks- it is set up for flat-bottom tanks supported on grade.You can use ASME BPV,Section VIII,to design the bottom head.Or you can use API-620,which can give some unreasonable results if
