Propane Tank Recertification?

"Q: I have a horizontal cylinder on my recreational vehicle. Are OPD's available for that kind of service?
A: The 2001 edition of NFPA 58 (the LP-Gas Code) recognizes that horizontally oriented cylinders that were manufactured prior to October 1, 1998, are unable to be retrofitted with the OPD's. As a result of this fact, the Code now exempts these cylinders from having to be retrofit with OPD valves. Any such cylinder must have a label affixed to it to inform the user and the refiller that an OPD valve is not installed. (Note: This provision was not contained in the 1998 edition of NFPA 58.)"

As to refilling tanks, I really do not see how it could be more clear than my previous post. It is from The National Propane Gas Association. It is possible they have changed the rules.

I have 11 vertical 20# tanks. Over time, I have had at least five of them recertified. They look at the cylinder, if only a few spots of surface rust and no modifications to the tank, they are OK. They attach a dated certification sticker, and log it in their book. They charged me $5 for the certification.

If I remember correctly, a new tank does not have to be recertified for 12 years, then it is every 5 years. I may stand corrected on this. This applies to vertical and horizontal tanks. All vertical tanks must have the OPD valve. As per The National Propane Gas Association, the horizontal tanks manufactured prior to October 1, 1998, are unable to be retrofitted with the OPD's. As a result of this fact, the Code now exempts these cylinders from having to be retrofit with OPD valves. Other than the OPD valve, they are still subject to the same certification rules as the vertical tanks.
