water volume load in a cylindrical tank

[superintended]

I need some good advice here. I've got a 20,000 gallon water tank with a slight problem. The tanks inside weld is only one eighth inch. My calcs show I need to put some strapping around the inside of the tank and get at least a quarter inch weld in order to hold the pressure. I don't have that kind of time. I need another "quicker" solution. The tank is 12 foot 2 inch diameter,31 feet long. I show about 170,000 pounds of water when full.

Not enough info given in your post. Is this a vertical or horizontal tank? What do you mean by 1/8 inch of weld... depth of penetration? size of fillet weld? What was original tank code?
