Seriously, the SS here costs about $1 a pound. I bought a 6 ft length of 1/2 SS for a few dollars. Those tanks would have been a couple of hundred each. A steal if a brewery can use them.
The pipes are around 2" diameter, but vary a bit.
If your takin' your girlfriend out tonight
You better park the car well out of sight
'Cos if they catch you in the back seat trying to pick her locks
They're gonna send you back to mother in a cardboard box !
