There is always the same answer to why steam pipes bang - water settles in spots to be picked up by the high speed of steam and slammed against bends. The solution is routine - be sure the pipes are large enough to pass the steam at reasonable velocity, make sure all pipes are pitched to drain water without bellies or dirt dams, lower the pressure to that just necessary to do the heating job, make sure the Hartford Loop is correctly installed off the end of the manifold beyond the boiler end, then check it all again.
