i am sure any oil field
pipe that is bent wll not be sent back over seas from where it
Just to note, non-straight pipe, 2 lally columns and a rope loop
with a stick can apply enough force to bend the pipe straight, a
hydraulic jack and a "U" frame will work better.
Start with a pipe and use a surface plate (monument stones work
well), to find a high spot. Apply pressure to the high spot to move
it slightly beyond the final target position. This is one of those
"feel" things, after a while you will know just how much beyond the
target you need to go. It will vary depending on the pipe and phase
of the moon, but you should be able to get below 0.001" run out
If you don't believe me, try it with some scrap, it works
Now, on monument stones, when granite is blanked for gravestones and
government buildings, even a small flaw can make it unsaleable. The
remaining options are: *Total loss, *use it as raw scrap, *find a
buyer. If after significant work to the monument stone (gravestone,
for example), the stone is to be discarded, someone who covers the
cost of raw materials and labor may be very welcome. Sometimes, a
six-pack of beer on a hot day will get you a broken headstone
missing a corner.
