Ok, that link shows propane, especially contaminated with high levels of H2S, affects pure copper test strips.
But I haven't found any references to "tinned copper" line designed specifically for propane in that doc, any of my code references, or in copperorg docs.
Personally, I have never seen anyn"tinned copper" line offered for sale or referenced by any propane dealers.
Unless you are referring to some new kind of tinning, the tinning I am familiar with would not tolerate being coiled, bent, flexed into shape as soft copper coils do. The tinning would crack and stress.
True, there are things I don't know and I learn things every day. But a requirement to use special tinned copper line specific to propane? That info and documentation will have to be pretty compelling to convince me ;)
I've worked with copper propane line over 40yrs old. Sure, they can fatigue and even become hardened, but so can water line copper. I'd speculate avg service life over 50yrs- more than sufficient for most rvs, IMHO.
(Not to confuse residential with special design/purpose industrial or laboratory materials)
I jnvite anyone with code and/or industry knowledge about this to chime in.
