DOT requirement for re-qualification WAS 12 years for 'portable cylinders'
That re-qualification WAS changed at beginning of this year to 10 years after date of mfg.
The MOST common re-qualification is a 'visual' inspection (condition of cylinder, has OPD valve etc)
Visual re-qualification is good for 5 years,,,,,,then another visual/another 5 tears etc
Visual Inspections costs: Free with refill at some places......$35/$40 at other places (no set price guide)
ALL portable cylinders (4#-40#) manufactured since 1998 HAVE OPD valves
By 2002 ALL cylinders would have been re-qualified and new OPD valves installed
Cheaper to have 're-qualification' done then buying new cylinders.
Cylinders can be 40+ years old and still in service
No reason to buy new unless cylinder has been damaged....dented, rusting thru, fire damaged etc.
I think the 10 year rule has been put on a temporary hold.
At least that is the way I read it at this industry website.
