Steel Pipe

Nuclear blast shelters made out of steel piping have incredible strength. I think the round shape gives them this strength. I saw one strength rating on another site which was 40 tons! It would be a pain getting the piping to ones location but I think its just a matter trucking it over and having some lame story to tell overly nosy people. I think the pipe could be easily insulated and waterproofed with any type of common spray on insulation - 2 or 3" thick. So far I definitely think the pipe shelter is workable but much more research is still needed.
