Tested this by setting the files to read only. I was able to use the pipes and the modification time changed. Guess that proves your answer. Can't upvote yet though.

I have just performed a test and, interestingly, just reading or just writing to a named pipe does not update its modification time. It is only when both reading and writing (or writing and reading) are performed that the modification time gets updated.
