I respect your information, but I just cannot relate to why their are different testing requirements. Testing simply because you disconnect the line?
I am not convinced that is the reason for the difference . Terminology becomes important in this subject . ASME propane containers are called TANKS , DOT propane containers are called CYLINDERS . ASME tanks are built to a more rigid standard than DOT cylinders , they weigh twice as much empty . To further muddy the waters , they could not come up with an OPD valve for the older ASME tanks so they were exempt . I know of no regulation that requires recertification of an ASME tank . That doesn't mean that there isn't one , I don't pretend to be an expert . Nine out of ten propane techs that I have asked have said no , ASME tanks don't need recertification . Still learning .
