Owner has received permission to cut out an overflow hole at the 19'elevation of a 73' dia. X 30' high tank so as to keep the capacity around 750,000 gallons. The current plan is to cut out 8" hole so that a 1/4" thick repad assembled with short piece of pipe and elbow can be bolted to the tank. The question now is can a 1" thick pipe flange(13 1/5" OD) be used instead of the 1/4" X 17 1/5" OD repad? I, for one thought, correctly or wrongly, that the repad thickness could not exceed the 1/4" thick shell plate. I also stated to form the repad to the tank OD which I don't believe that you could do to the flange. Owner also wants only four bolts but I believe that 8 bolts would be better for such large OD.
