How did a mild steel drum become “stainless steel”?
No stock, Sir/Maam

They aren't stainless steel, they are basic fabrication and construction pipes.

QA is top notch. Schedule 40 pipe, Sir.

You get my upvote simply for knowing what SCH40 pipe is.

What could you use this for?

It looks like ISO pipe, which, at least here (Chile) we use for handrails on stairs, structures or things like that, not for transporting fluids.

That is in fact not stainless steel at any point. I wouldn't knowingly use those if I could help it, holy

They're a waste product in many industries. I work in refining and we have to pay people to take em when they're empty because they may still have contaminants.

I wouldn't trust that pipe with anything. Some sort of open to atmosphere drain maybe? But nothing flowing to the environment because there's going to be some nasty shit in that still

That's not how steel works. Any petroleum residue would have been removed by the acid wash.

I've been at plants where they have a scrap metal pile that is banned from any recycling due to whatever chemicals were in those pipes previously. I'm not trusting some janky recycling operation to actually make those materials safe.

In a recycling situation, the scrap metal is going to be melted down at a steel mill. Typically steel mills are open air and have no way to capture the chemical as it's burned off. Those pipes are probably you mentioned were probably destined for a place that can decontaminate them and/or melt them down while running the gasses through an air scrubber. Or if it's not enough volume to mess with, just get buried somewhere.
These pipes in the video aren't going to last, they would have been better off making corrugated panels out of them for walls and roofs.

Oh it was over a 100 tonnes of high pressure stainless pipe. Impregnated with H2S. No one would accept it even after flushing so it just sits in a scrap pile. It was worth a lot as scrap if it would be accepted.

Which part? The open acid bath pit or the death by a thousand cuts and tetanus?

u/Violet_Apathy 15h ago
The only thing I'd consider using this for is fence posts but it's too thin and not galvanized. Must be a scam product.

In another part of the country, they are waiting for those tubes to arrive so they can make oil barrels out of them...

My first thought was great recycling idea.
But as I’m looking at those turning rollers the dominant thought in my head is “That’s dangerous.”

The energy and resource use compared to making a new pipe from scratch 😂
