Return them Yes - Return them No

[OMyMyOHellYes]

Send them a box of tissues and a small violin.

An option is for them get the cylinders "retested" and stamped in the correct and commonly accepted standard place on the shoulder. And the side-stamp properly painted over.

It is not a "paint over ugly side stamp so it will look pretty" issue.

Pendantic mode: 2¢ worth as my outlook may be a little provincial - but I'd be skeered of em.

Stamps on the side wall of cylinders is criteria for automatic condemnation of cylinder. Not failure/rejection-problem cannot be fixed. No remediation allowed. Condemnation. Trash. Deface the bottle/XX out shoulder markings except S/N and hydro stamps. Cut the bottom off and make a garden bell out of them. At least for US DOT/UN-ISO certified cylinders. Are AUS cylinders certified to UN-ISO standards?

Or US Federal regs - from which (I assume from which the above PSI-PCI guidance springs) (which would not necessarily apply to non-DOT bottles, but I would strongly consider and reject and not use based on that factor.)

Oh - I have never seen a vertical stamping. that would be cool. All the hydro stamps I've seen are horizontal, parallel to the original factory roll marks.

I don’t think paint will fix that…they should be condemned I believe..

Damn what a waste of some shiny new tanks

 

[Marie13]

What’s with that big AIR on them? Is that an Aussie thing?!

Fortunately unlike the stamps, those stickers can be removed

 

[sea_ledford]

They are new tanks, correct? What are they even stamped at all? Shouldn't the original mfg date that is already on there count for the first hydro? Or is this an Aussie thing vs a Yank thing?

Also never seen a vertical stamp for a hydro. It might make them easier to find though!

OP lives in another country not subject to those specific regulations.

 

[runsongas]

without checking the relevant australian standard (i believe it is AS2030.5 for cylinder inspection and requalification), the side wall stamp may not cause an automatic condemnation

definitely return the two with the side wall stamp if you plan on cave filling. it would have to be like a 75% refund for me to live with a side wall stamped LP steel (assuming the side wall stamp is ok per australian standard) as it likely is fine for pressures under 3000 psi still

I don't think you will be a happy diver once you receive the answer. Name the culprit.
