What is this?

It's not a pipeline section, too flimsy. Judging by the background paintings,(or is that graffiti?) maybe some part of a circus act?

That crane looks too heavy for a traveling road show.

I don't know.

:-D

If it wasn't for Fred, I would know nothing!

But you wouldn't know that.

Beat me to it, I was going to guess that because what else would it be.

Obviously a short test.

A train will go through that?

The internal lifting supports implies to me that this pipe is not strong enough to support its own weight, let alone the weight of a test train inside of it. Maybe the photographer snapped the image of a flash flood drainage pipe or some other operations support structure but that tube does not look adequate to me to put a train inside, let alone hold back the pressure differential of a vacuum to desert air pressure.

my understanding the section is for a "test track". I also read it will not be in a vac but a "low pressure" state of 0-+1 PSI

In a vacuum, nobody can hear you scream....

...what?

What if you thump the side of the tube really hard?

See #7. And then the internal train will be squeezed out like toothpaste.

A bigger version of "nightcrawler's" tubes, prior to external pressure collapse.

A piece of microbore pipe being installed for a KrisDel^TM "Maxiconomy"^R domestic central heating system? No? Oh well. Never mind.

...it's the cross-hairs eyepiece of a rifle designed by an engineer of the old school forced by company policy to use common core maths.

Its called a "can". The roll direction is transverse to the length. Somewhere there is a long seam probably made by SAW. We make them here all the time. It is normally made by the 3 roll system. Yes a cold roll for that gage.

Looks similar to a rolled and welded tank cylinder that we fabricate here at work, then add top/bottom/legs/ports/and so on. Maybe a 4000 gallon process tank. Many smaller firms have them ordered, and trucked to them, as they can't roll a cylinder that large. Incoming tank cylinder for a small tank builder?

New Brigade Size MRE?

Re-enforcement wall assembly for an underground duct?

It appears to be a short section of conrete lined pipe, typically used for water supply main lines. This one is probably going in near a curved section, or near a valving/pumping station.

Campbell soup test ? See what floats.

Easy, is a CAN section for a deep water offshore Pile
