ASME standard for returns ?
ASME standard for returns ?
(OP)
Which is the correct standard to use for specifying buttwelding return type piping components(180 deg elbows)? ASME lists 2 standards as far as i can see:
ASME B16.28 - wrought steel buttwelding short radius elbows and returns
ASME B16.9 - factory made wrought buttwelding fittings (std. lists both short and long radius returns).
They can't both be valid can they ?
ASME B16.28 - wrought steel buttwelding short radius elbows and returns
ASME B16.9 - factory made wrought buttwelding fittings (std. lists both short and long radius returns).
They can't both be valid can they ?





RE: ASME standard for returns ?
B 16.9 - Factory made wrought steel but welding fittings.
B 16.28 ASME B16.28 - wrought steel buttwelding short radius elbows and returns
