You can get these tables from many places on the internet. Basically you can get carbon steel and alloy pipe in Sch 5, 10, 20, 40, standard, 60, 80, x-heavy, 100, 120, xx-heavy, and 160. Although they list it in these sizes, In the USA It has been my experience that stainless steel pipe in Sch 5, 10, 40, 80 is more common than some of the other listed sizes. I have several different pipe handbooks that are given out free by prospective pipe and fitting vendors in my area that are a very good source of information. If you could ask your vendor he might be willing to donate one of these books to you if they have them where you are located.
