I didn't know that there were swimming metal walls.
above ground pool walls have insulation in them
Polymer. Metal rusts, polymer can't.
I suppose that the recommended solution is to send this cylinder to metal scrap.
That would be doubtful. The pressure of all that water would open up the repair like you cut it with a knife. You are going to have to replace the whole liner as one piece.
Connect it to the frame/chassis -- the major metal parts of the car, such as the walls of the engine compartment.
Is that What product or material can be used to cover metal walls? or What product do I use to cover metal walls?
mainly because they are rated on BTU size...
A house is built from the ground up. It starts with a good foundation. This can be either a solid concrete slab or pilings for a house above ground. Then you add walls and a roof.
So that the water doesn't drain out of the pool and so the pool doesn't fall over. I agree with the answer above but I have a more detailed answer. In a round above ground pool the water puts even pressure on the pool walls, and if the ground is not level one side will get more pressure. The imbalance will cause the pool to collapse under the strain.
No
YOU WILL NEED TO CHECK WITH THE MANUFACTURER .SOME ABOVE GROUND POOL OUTER WALLS ARE TREATED WITH AN EXTRA COAT OF PAINT OR TYPE OF PRODUCT TO KEEP WALL FROM RUSTING DUE TO CONTACT WITH SOIL.
As long as the water entered above the ground surface level.
