Acid proof container

[wristpin]

I need a fairly robust vertical plastic container for immersing fairly heavy items, some 36" long and 6" in diameter in a de-rusting solution (dilute phosphoric acid) . At present using a plastic drum with the top cut out but it's not deep enough and items have to be turned and the newly de-rusted end then starts to rust again.
Have considered a dustbin but the volume is considerably more that I need.
Thinking maybe an off cut of 12" plastic water main pipe with a cap "welded" on if I can find a source.
Suppose I could make one with fibre glass but guess that would have to be moulded around weld mesh or similar to give it strength.
Any suggestions for an off the shelf solution ?

I use a length of drainpipe with a disc glued in the bottom.
A wider tube would be ideal.
Just be careful emptying it, tip it, tip it kersploosh.
A hideous green mess all over the floor.

Brewing bucket!! or a 60l drum?

space saving water butt?

What about a simple wooden frame lined with HD plastic (DPM or pond liner) ?
Another idea is a 20/25 litre plastic drum. Cut top off and then cut down the middle. Join the two halves together with silicon held together with plastic no. plate nuts & bolts.

Couple of other options. Look out for the guys laying that yellow pipe in the paths and roads (seams to be doing that all the time round here!) might even get an end cap from them as I think they have caps on it for storage/transport,
Another option is get one of the smaller size wheelie bins (phone council to say yours is missing ) and to avoid having to fill it with lots of phosphoric dilute you could get some old 5 liter containers, fill with water,cap and use them to "bulk out" the bin to reduce the volume of deruster needed. I have used the diluted phosphoric (the BnQ metal restorer which they no longer do, gerr) Have now been trying the brick acid (cheaper!) from ToolStation. Does not work as quick but does work. You might even find if you shop around you could get a 25lt drum of it for what you pay for the phosphoric.

ps Any one know where you can get the "Swarfega metal restorer" for a sensible price? now that BnQ don't do it

2mm of fibreglass is more than enough in a tube, as long as the resin is resistant to the contents.

I cannot check the data but as Chunkolini says, uPVC should be fine. It is available in sizes well over 160mm diameter as ducting, about 3mm wall. Any plastic fabrication shop could weld a plate to one end, like mine for instance, but a bit far away.

Thanks to all for the suggestions.
Looks like a 100ltr water butt from Wickes will do the job - it's even got a lid. If I can find a bit of thick plastic I'll cut it to fit the bottom to stop any sharp edges doing damage; if not a bit of exterior ply will do for time being!

Our local agricultural merchants sell used heavy duty blue plastic barrels for a fiver.

As soon as I read this I was thinking the same kind of thing. Depending on how wide you need it. And this was the first reply added.
