That's probably all it is, the pipes rubbing against joists, floorboards and other pipes, you could lift the boards and insulate/lag the pipes and enlarge joist notches if the pipes are a snug fit. Also clip the insulated pipework to the joists so that they don't touch and rub on floorboards etc.
Nothing to worry about - although the noise may be annoying.
