Does anyone know of an online publication or book that has surface area for most common weld and forge fittings? I am not worried about too much detail, but a basic table would be of a great help.
I am looking for surface area of each fitting type and size for coating estimation. Surface area of pipe is an easy calculation, but the fittings are tedious to tabulate, so a table of exterior and interior area would speed things up. I can find all the dimensional information, just looking or a better reference for coating application.
