Which is why my shop uses CI for the compressed air. Cut to length and use a pipe threader in the lathe to cut the treads (manual turning of the spindle).
Worked in one shop in FL that used schedule 80 PVC and glued fittings for the compressed air. It was located just above the drop ceiling and you should have seen the mess when a joint came apart. Not just ceiling tile, but several needed to change their drawers.
Luckily just the joint came apart instead of a pipe blowing which tends to send shards a flying. PVC also becomes brittle with age and even more so when exposed to light.
