    Re: All about tanks

    I agree this really doesn't prove anything. The car next to it looks pretty good, was burnt a little from the fire but does look like explosive damage to it. And this was arson. If this was in the real world hopefully the driver was smart enough to get out of the car when it's was on FIRE. This explosion occured because the PRD failed. The same thing can happen to a gasoline vehicle or maybe I've seen one too many films. Don't think your gas tank has a PRD.

      With as many illegal shops and shadetree mechanics as there are at work in Utah these days, I'm thinking this Fourth of July could be a doozie.

        I am not trying to debate your statement (as if to say you do not know what you are talking about), but explain why this sticker exists? It clearly specs a retest date ...

          Might it be the re-cert sticker is from a previous era when you could recertify tanks?

            Some steel CNG tanks can be recertified.

              I am only guessing as well.

              Any company can have any sticker made. Re-Test is not Re-Certify.

              It looks like a service company made it as advertisement/documentation the they inspected (tested?) the tank. CNG tanks are supposed to be inspected every three years or 36,000 miles.

                Did you look at the sticker?

                An inspection was done in 03 and the retest date is 2014. A wee bit more than the 3/36 spec.

                  Jblue,
                  Do you have this tank or know it's date of manufacture? 1999?
                  This sticker has many levels of confusing information. Is it an inspection sticker or retest/recertification sticker? Is the tank Dot 3AA or NGV2-2?
                  As far as I know from NGV Cylinder Inspector Certification Class, NGV-2 cylinders are no longer pressure tested due to it's destructive nature and are certified by the manufacturer for 15 years (20 years on some Canadian cylinders) from date of manufacture and that's it. They are required to be visually inspected every 3 years or 36,000 miles, which ever comes first.
                  DOT 3AA cylinders or bottles which are used in stations, storage trailers and boats for use on stoves are pressure tested and recertified every 5, 10 or 12 years, depending on type of use. If certification stamp or marks are no longer visible, a stamped metal plate may be used for identification. DOT 3AA cylinders are no longer certified for use in NGVs in the United States.

                    cool. Thanks for rehashing that for me!



                    I think what they did is use a 3AA sticker and filled in NGV2 info ...
