Standard: JIS G3459 (stainless steel pipes)
JIS G3459 covers seamless and welded stainless steel pipe for corrosion-resistant and high-temperature service in the Japanese system. Its outside diameters differ slightly from ASME B36.19M at some sizes (21.7 mm against 21.3 mm for 15A / 1/2 in, 27.2 against 26.7, 42.7 against 42.2), so JIS pipe and ASME fittings should not be mixed without checking.
Sizes are designated A (millimetre series) or B (inch series). Masses are calculated for austenitic stainless steel at 7.93 kg/dm³: W = 0.02491 × t × (D − t).
