Propane tank age?

[bmargiotti]

i tried to search and am surprised that i came up empty.

what the max age for a residential propane tank? im thinking 15 years, and if its recertified, how may more? cant find anything in NFPA to back it up.

Cylinders are subject to recertification (also known as requalification) twelve years from their date of manufacture and every five years after that. For example, a cylinder manufactured in January of 2000 will have to be recertified in January of 2012 meaning if you take your bottle to the propane company in April of 2012 to be refilled, it will have to be requalified by authorized personnel before it can be filled. The recertification process is simple and does not take too long to complete. Think of cylinder recertification as an inspection similar to that of your car. A vehicle has to be inspected annually so that it may continue to operate safely on the road. Similarly, a propane cylinder must be inspected so that it may continue to operate safely in LP Gas service.

ASME tank have a nameplate that should have the date of manufacture and be in good condition. No requirement to re certify.

I have some 20 gallon DOT tanks from the 40's or 50's, some guy at the propane shop sprayed them with soapy water and punched a new date into them the last time I had them checked.

do you mean 20# tanks? BBQ type? if so, im sure this is a no no as tanks have to be equipped with the new overfill valve to be filled.

For being so sure about pressure vessels you ask a lot of questions.

Who said anything about valves???
