Compare it to something that feels similar.
Are you asking about tubing or pipe? There is a big difference. If are you asking about nominal 1 and 2 pipe, they will have a outside diameter of 1.315 and 2.375 respectively. Such pipe can be purchased at any home center, hardware store or plumbing supply store. If you are asking about tubing. It comes in outside diameters of 1 and 2 but tends to have a relatively thin wall thickness and that doesn't lend it to having threaded ends. Tubing is typically connected using special tubing fittings or by direct welding. You can usually find tubing at a structural steel supplier. This will not be the type used for containing fluids under pressure but might work depending on what you want to do. Pressure containing tubing would probably only be available at a supplier of industrial pipe for refinery and process plant use.
It might, it might. Was it poisonous bread and the only antidote is hydrant induced head injury? Maybe you should ask yourself that question
