Replacing Propane Tank

OP was informed/reminded on couple of his previous posts about re-certification and was given links to the ASME/NFPA standards/chapters concerning ASME propane Tanks.

His original problem stemmed from propane vendor not re-filling his propane tank because of the rusted condition (think propane vendor told him it was out of date and needed re-certification so he would go away----or buy new tank from him)

I am the OP and was never given that link. However, I did submit the last post in a thread where that link was given. That's about as close as we get.

THAT link addressed portable cylinders and doesn't indicate the difference with ASME tanks. A propane supplier that's been engrained with the idea that all propane vessels are portable cylinders could have difficulty with a customer that insists his vessel is in compliance.

But here's the smoking gun:

It describes ASME tank construction perfectly for what we have in our Class A's. It indicates no re-inspection according to this document. It doesn't have an official US DOT or PHMSA seal/logo/whatever but that's good enough for me. I got it by doing a search for 'propane' at US DOT Pipeline, Hazardous Materials and Safety Administration's website:

The jury is out whether my RV shop is a crook or ignorant of regulations. The rust is a major turn-off but shouldn't be an issue with tank integrity. He should know that.

Here's that link on portable cylinders again:

I'm going to print both copies and be prepared for the next propane purchase. This has been a real education.

Guess I'll start looking for sandblasting equipment.

Thanks everyone.

Best,
