What’s up with the very thin airgun barrels.

I have noticed that many airgun barrels are so thin. Is it because there are less pressure than powder guns. I disassembled my pp700sa and my god under that shroud is a pencil thin barrel. I can’t even see the crown. Also with the muzzle end being threaded there is not much room from threads to crown that the edges of the muzzle is ragged. I have to take the sharp edges off and re crown barrel with brass cone and lapping with valve grinding paste. I’ll take pic of that. Second I used my barrel camera to look inside OMG I don’t know why this barrel shoots lights out with the way it looks.
A BB being fired generates no heat. A bullet does.
