Piping design codes

A question occurred to me as I clicked 'send' on the last e-mail. Does anyone on the list _not_ use one or another of the ASME B31.x piping codes or a national standard that isn't substantially similar to the ASME Codes. Although I haven't used them, I know that some aspects of the British piping code and the DIN standards are different, certainly in the units of measure, but that isn't nearly as important as the design criteria.
