What to do if the piston cap of a reciprocating compressor cannot be removed?

It still can’t be removed even after heating it with gas cutting – does anyone have any good suggestions?
Mechanical grinding, destructive removal. The thread must be damaged.
Just give it your all; leave the rest to miracles.
Previously, we stipulated that heating the piston and its cap with fire was not allowed, as there might be materials inside. There was a small explosion due to overheating.
This one requires a heating rod; it’s been taken apart in this way, and the threads are likely damaged
Hey, we encountered this situation – no need to overthink it; just use oxyacetylene cutting to cut the nuts directly.
If it doesn’t work, just get into the bed frame; it’s better not to start heating it right away
The piston of a reciprocating compressor is a hydraulic nut. It needs to be compressed to relieve looseness.
First, confirm whether the threads are right-handed or left-handed; then use manual tapping. If that doesn’t work, apply a loosening agent. If that still doesn’t work, use an oxygen torch along the edges, combining it with mechanical action while blowing
