Steam pipe banging
One pipe residential steam pipe bangs when heat come through the system. There is most likely condensate in the pipes. Can I drain the boiler and leaving the drain open disconnect the radiator and blow out the pipe using a shop vac? Do you think that would get rid of the condensate and stop the banging?

There might be water coming up with the steam. Or there might be some condensate in the return pipes. Don't have the water level too high in the gauge glass. Only half or slightly higher . Water might collect in the return lines, ether if the lines are not pitched right, or there might be mud in the lines, especially ,if the pipes run along the floor.

Blowing out the condensate won't work because more condensate will accumulate in the same places, perhaps within four hours depending on how much time during the day the boiler is in operation.
Sometimes jacking up the radiator (and setting it on small wood blocks) will fix the problem but do not use force. The pipe under the floor would need clearance above it to regain an upslope towards the radiator.

Most of the time the noise is caused by improper boiler piping, boiler surging, oversized boiler, pipe hangers missing, no insulation on the steam main and poor venting.
Please post some pictures.
