Introduction
Piping is divided into three major categories:
1) Large bore pipe: Generally includes piping greater than two inches in diameter.
2)Small bore pipe: Generally includes piping which is two inches and smaller in diameter.
3)Tubing: Tubing is supplied in sizes up to four inches in diameter but has a wall thickness less than that of either large bore or small piping.
