I mentioned in a previous post that I acquired 5 21' x 1" gas pipe from my company after shutting down a plant. I probably won't do anything for a long time but eventually installing my tankless water heater and moving heater to attic.

My question on storage: is it ok to store under my house with end caps installed and should I cover with any type of grease to prevent rust? My house is on a raised foundation and basically dry underneath but it is subject to outside air blowing in thru vents. I would also set on top of bricks or something to keep off the sand. I want to get off my driveway before winter and rainy season arrives.
