Wait till the water level is high enough to cover then damage then sell!!!! Seriously, this reminds me of one of my corrals that was built out of used oilfield pipe. It has rusted from the inside out and the oil field guys tell me it had acid in it when it was taken out of oilfield service and that is why it has rusted/rotted away so bad. CowMan
I bet it was to. We used to sell that stuff all the time out of wells when plugging. Set up the workover rig, pull out as much pipe as possible, and seal with concrete. Texas used to have an abandoned well plugging program that made it pretty profitable because they did not know the operators could pull pipe for extra money. Who knows how old that pipe was before it was ever used on the dock. We used some for pipe fencing on a 90 acre horse farm and the salts would leach out and flake the paint off every year. A lot of wells had salt water and sulfuric acid in the pipe from drilling around salt domes. Sorry, I don't have a solution, but figured you might wnat to know the reason.
