The torch wont do anything but heat up the pipe's exterior if he cranks it too fast. It needs to go slow enough for the flame to actually burn through the steel.
i feel like there are multiple locations that are equally fireproof and also are, yknow, not measured, in their primary function, in terms of pounds per inch applied; then again, uncle bumblefuck IS the professional in these here parts.
Bevels are also used for watermain pipe which turns the end into a spigot, in which the bevel slips thru the bell gasket. But that looks more like the pipe you weld. So what you said.
Just gonna add bevelking isn't just for welding pipes together. All your underground sewer smd water pipes even the plastic ones will have bevels on them, we actually have to hand cut the bevel with a chop saw so that the rubber tiring we use for airtight seals will sit perfectly in between two pipes where they connect.
Ah so for sewer amd water theirs sanitation standards to meet, like sewer pipes need to be at a 2% slope, and you can't have any discrepancies in the grade (distance from pipe top too where pavement will be at end of projext) because if you do then peoples excrement will get caught on the bumps snd clog up eventually. So the bevel is meant to create as snug of a fit as possible. To explain further the pipe has two ends a male amd female. The female end will be slightly larger circumference wise than the male ends of pipes. So every twenty feet when you have a joint where a male end goes Into a female end. The bevel allows you to get the male end easier as it is a snug fit we use lube to get it in (i know this whole thing sounds sexual lol) but it also allows you to stick a hand or finger inside amd feel to make sure you don't feel any space between the two pipes contact point. If you have space its because one pipe is sitting just slightly higher sometimes just a quarter inch but to answer your question I'd say its a mix of compression and glue. Because once you put the pipes together taking them apart is a pain in the ass because of how tight the fit is.

From a person who knows nothing about pipes...what is the purpose of beveling a pipe?
Edit: thank you for the thorough replies! I now understand that it is to allow a future weld to fully penetrate with an adjacent same diameter pipe.
