Thanks Rob for finding that. I had no idea wood pipe was still being manufactured in 1942.

I imagine that the war had a lot to do with it! :-)

That's the most plausible explanation I've heard so far.
Comparing the load to the flatcar says these things are about 4', maybe 4'-6" max, in diameter. That's a reasonable size for water piping. Two to a car longitudinally says they're 20' long more or less, which was and is a common length for joints of pipe.
I found a 1942 catalog of wood pipe which claimed extensive use, even at that date. The war probably boosted its use a bit. http://www.waterworkshistory.us/tech/Pipe/1942WoodPipe.pdf
Not incidentally, they also built water tanks, which if I recall correctly had some use on railroads when they used those external combustion locomotives.
