TECHNIQUES METHODOLOGIES FOR TANK BOTTOM

As the whole shell of the crude oil storage tank is welded to the tank bottom plate,development of leaks on the tank bottom plate leaves the maintenance personnel with only two options (a) To do away with the leaky tank and erect a new one.(b) To replace / repair the tank bottom plate.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextTechnical Inquiries for API Standard 650,Welded TanksIs it permissible to use Group I plates for a tank bottom,except for plates welded to the shell,for tanks with a -50 cylindrical welded storage tanks bottom plates welded to the shell#176;F design metal temperature?

Annular/bottom is realised from shell by cutting or gouging Complete tank is lifted,allowing annular and bottom plates to be removed. As example 800 mm lifting height of tank. The tank lifters must be located on the outside of the tank and with a distance to the shell making sufficient space for the new foundation to be made.Sample Report for Storage Tank Shell Structural Profile The tolerances given in API 653 Table 10.2 the max Permissible value for Radii measured at 1 ft.above the shell-to-bottom weld shall not exceed +31.75 mm (Tank Diameter (Feet) cylindrical welded storage tanks bottom plates welded to the shellgt;250).Radius tolerances measured higher than one foot above the shell-to-bottom weld the max Permissible Radius tolerances
