Water/Steam hammer need solution

The pipe bangs when steam reaches the rad. Pretty obvious why it's hammering if you see the pictures. Any way I can fix this? It was mounted to the wall but pitched incorrectly and banging. I took it off the wall and added a glass bottle to pitch it but still banging because the bottom part is not pitched. It also gurgles after it stops banging. I don't have a lot of space to remove the pipes

    There is probably a horizontal pipe under the floor that is also pitched the wrong way and holding water. See if you can lift the pipe up some (that will add pitch to the horizontal pipe under the floor) Then re-pitch the radiator.

    I tried lifting the horizontal pipe but it won't move. Any recommendation on what to use to pitch it? It's about 4 inches high

    Has it always hammered or is this a new problem? If that pipe won't move, don't force it. You may break something.

    Always hammer since day 1 of moving into this home last year.

    Are you collecting water in the 90 under the valve?
    Is that a real steam radiator or hot water wantabe.

    It is collecting water under the valve. This is steam. Pitching the lower pipe is hard since the horizontal pipe isn't moving.

    Is this in a bathroom? Do you need that heat? If not, you can turn the air vent upside down and that will prevent steam from getting into the radiator and should stop the hammer.

    If the basement is not accessible, an option is to replace the 90's with 2 45's to assure draining.
    Old eyes here, hopefully that is 1".

    is that valve open all the way ?
    it should be,
    after that it might be worth disassembling the valve, and checking the internals are working and not disconnected and holding back condensate.

    It is the bathroom. I think my wife wants it on.
    It's not in the basement. It's probably best to remove the 90s and replace with 45s like you said.
    I did take the rad off to clean it and look inside. Valve is working fine
