Can ASME B16.11 used for designing machined square head npt plugs? Also, is there any reference to the maximum chamfer or fillet that can be given in square heads?
ASME B16.11 defines dimensional size and tolerances for forged fittings. One can design a fitting and manufacture with machining operations to the dimensional size and tolerances. Chamfer limits are specified within the referenced text within the standard.
