Can the power of PH help identify these objects?

Hi all,

I'm helping a friend this weekend in clearing out a storage unit full of junk and equipment. We're trying to sort stuff by "scrap" and "sell".
We've come across these big column things and can't figure out what they are. They are stainless steel, about 3m long, with 1 threaded and one plain coupling at either end. Judging by the weight, they aren't hollow but must have some sort of internal pipework.
I've tried extensively googling the name "Spiflex" as stamped onto them, but have got nowhere.
Whatever they are, given the workmanship involved it would be a crying shame if we had to scrap them.
Does anyone please have any ideas? Thanks in advance!

Having googled cooling tubes, these look pretty similar...

Not sure what they are, but the end fittings look like hygienic fittings so probably dairy equipment possibly pasturisation process heat exchangers.

Nuclear fuel rods?

Yup. Heat exchangers.

Yeah they’re heat exchangers. I used to work in a place that made malt extract and used them.

Stainless is fetching 70p to £1 per kilo. Phone the breakers and ask before setting off. Even adjacent sites may offer different prices.

See if you can see 316 stamped on it anywhere. That's the more valuable type.

Many thanks chaps!

So, they are dairy heat exchangers then? IIRC food grade stuff is usually 316 so I suspect these must be.

I presume the market for these secondhand is extremely limited? I guess I can always try ebaying them for 2x predicted scrap value...

[DickyC]

Worth more scrap and you don't have to deal with eBay.

Can they be used as part of a homemade still?

Asking for a friend.
