    Hard to see/understand your sketch

    It looks like you come off the top of the boiler into a tee? Any equalizer? Please take a pic of the boiler and the near boiler piping. Also I noticed you posted twice. Will be more helpful to you if you keep all your question under one thread.

    When do the pipes bang?

    Beginning of cycle, mid cycle, end of cycle, or all the time?

    banging

    reinsulate the piping, no insulation will caus the steam to condensate to quickly, not crazy about the piping job, read boilers piping in the book
  • Boiler piping bad.....

    the boiler piping is completely incorrect.  The supply piping is wrong which is probably causing water to be thrown into the system, whichin turn  usually causes banging.  The return piping is also wrong.  The piping labeled Harford Loop is actually not a hartford loop at all and does not provide the safety feature that a Hartford loop provides.  Find the boiler installation manual(in the rafters or online) and compare the recommended piping to what has been installed.  I have only come across one boiler manual that considered that supply piping proper....a mid 1960's Weil Mclain gas fired model. 

    That all said, getting a knowledgable steam specialist in there to look at the system may allow you to stop the banging without repiping the boiler.  Insulating the piping and making sure it is sloped to drain water out of the piping are places to start.  More info and pictures of the system (and radiators) will help clarify what may need to be done.
