Aboveground storage tank piping

[mufasa1]

In our boiler plant, there are two fuel-oil ( aboveground, flat bottom )storage tanks.
The tanks are around 14m in height and 10m in diameter. We will add an additive to fuel oil. In order to do this we are going to take an 8" branch from the existing line, this line will pass through an equipment to get the additive and later climb to the top of the tank. So the fuel oil will be fed to the tank from the top. The main problem is How can we get the 8" line climb to the top of the tank. There will not be much vibration during operation. How will the tank mechanical integrity react if we go ahead and attach this pipe w/supports on tank body? I need info and starting point on this. Will appreciate your guidance on this matter.
Thanks

sir
i would not recommend to support the pipe from the tank.
it should be supported independently after doing proper stress analysis. further check velocity of the fluid thru the inlet nozzle at the tank -should not be higher than the usual recommnded values.
most important-take the inlet pipe down so that the pipe is submerged in the tank liquid level.

Krishnan,
Thanks for the valuable info. What do you think about taking the weight of the pipe with supports on the ground and just attaching it to the tank for guidance?
