Steam heat pipes near wood

There are some wood beams from an old wall frame in our basement that run right along the top of the 2″ steam heat pipe that is dropped down from the ceiling to serve the upper floors. I’d like to use the frame to run down some shelves, but is it safe to have bare wood so close to the pipes? They do not touch, but are a fraction of an inch apart-

What are the guidelines for wood around heating pipes and radiators? There’s no room to wrap insulation around the pipe in this spot – is there another treatment I can use (on either the pipe or the wood) to make this safer? Is it particularly dangerous to being with?

Thanks-
