Pipe soundproofing
There's a pipe that runs between the floor and ceiling in the corner of my apartment bedroom that makes periodic hammering noises related to building heating that plumbers I've used claim they can't fix. As at least a temporary workaround I'm considering using soundproofing to dampen the noise. Any recommendations on specific products or product categories, especially if they've worked for you? I've already looked at soundproofing wrap etc and may benefit from further research and advice. Thank you.

Ok..... so it's 8" in diameter. If it's used for heat we can assume it's an iron line and gets very hot.
That's going to take a lot of insulating and I'm not really sure anything is going to quiet noise from a pipe that big. If it's a steam system then what you're hearing is a banging inside the pipes where cold water meets steam.
The most effective way to quiet it would be to box it in but that is pretty ambitious.

@ PJmax
Sorry I meant circumference; just corrected my previous post. Idk if that changes much.

So it's probably a 2" pipe with a 2 1/2" outside diameter. As PJ mentioned it's going to be tough to quiet it down. You can frame out a chase around the pipe. Add sound insulation and sheetrock the outside. This would give you the sound absorbing of the sound insulation and the physical barrier of the sheetrock to totally seal off the pipe from the room. If you are renting you can try covering the pipe in sound insulation alone but it probably won't be as effective. High pitch/frequency sounds like ticking are easier to muffle but deep thunking or banging is harder to block.

When building, I use Roxul SafeandSound, which is a rockwool insulation. It's heavier than fiberglass, and helps with noise a bit. For an apartment, maybe a somewhat heavy area rug would help (think oriental rug weight). You can get soundproofing mats, but they get pricey quick, and you'll need some way to keep them hanging vertically.
Whatever you choose, the heavier the material, the better it'll block sound.
The pipe itself isn't moving when it bangs, right? It's the water or steam in the pipe?

I own, not rent. Pipe doesn't move. Used fiberglass insulation as didn't find wide-enough foam insulation at the usual stores near me; seems to do enough.
