How to Straighten Bent Pipe WITHOUT Crushing It

How to straighten bent pipe without crushing it.

Wood blocks, Press, Stepped Drill Bit or Hole-saw

Cut a hole in a wood block SLIGHTLY larger than the outside pipe diameter. The closer to the pipe size the better. This hole is what keeps the pipe from being crushed.

Slide the holed block onto the pipe at the bend.

Set the ends of the pipe on wood blocks taller than holed block.

Align the pipe with the bend facing up. Align the holed block so the wood grain is HORIZONTAL.

Use the press to bend the pipe back into shape. You will probably have to press more than the bend because the pipe will want to spring back.

Do a little at a time.

It helps to pre-mark the high spots on the pipe with a marker.

Repeat for each bend.
