Nick Bennett Posted August 16, 2006 Share Posted August 16, 2006 A discussion (on another thread) about the thermal expansion of pipes has led me to wonder whether pipemetal has the same physical properties in both directions. Do pipes have to be made the same way round in the metal, or can some be made along the length of the sheet and some across it, if you see what I mean. If somebody were to cut a piece out of a sheet of pipemetal and leave it on the bench, would anyone entering the room and picking it up be able to tell which way round it was on the bench when it was cast?
