Only thing I know to keep in mind with pressure testing anything is to make sure it is fully filled with water first, if the vessel is no good it will just spring a leak instead of going bang..
Just on that, I'm fairly disappointed with the replies or lack of from businesses I have emailed in regards to fermenters.
Not sure if I don't sound serious enough or a too smaller fish either way it's looking like building my own is going to be less frustrating and probably cheaper.
Welcome to the world of trying to get quotes - takes a long time - sometimes I wonder how they make money. They should reply, but is often after a week or more.
I would be supprised if a fermenter had to be a certified pressure vessel, any idea where you got that from? Large vessles, like 400 tonne coal bins and the 1 million litre fermenters at Manildra are engineered by assigning a pressure to the inside wall, but the top is open in so far as the coal bins (the pressure is purely a result of the height and density of the contents) - not sure about the largest fermenters in the southern hemisphere though - could this be it? I'll ask someone.
I reckon building it yourself would be great. A blinckman next to your rig just wouldnt look right.
To get over your 70mm rolling radius, perhaps machining or lathing the bottom bit from a SS billet could be the go?
Theres plenty of metal spinners in Australia capable of spinning some SS.
As for getting quotes - email sucks. Use a fax and follow up with a phone call. Give an appropriate amount of time for them to prepare a quote 5 working days is typical minimum turn around time for a quotation request to be turned around in manufacturing industries for joe blow off the street. I spend millions of dollars a year with many of my suppliers and im lucky if I get a next day quotation filled and they know my leads have genuine purchase order potential. Theres a reason procurement officers earn a decent living
I am told that commercial fermenters are open to the air (not pressure vessels conforming to the pressure vessel code), perhaps with some sort of disk valve within a large diameter pipe coming off the top. Sounds like a heavy metal disk valve pivoted on one side so the other side can raise up from co2 pressure releasing it?
Sorry if it is obvious but I have looked and thought and looked and thought...
WTF is that tube thingy for?

Well i'm going to use it to chuck hops in and recirculate through the kettle, its outlet is behind it.
Awesome.
So like a hopback on the way out? Hot wort, on the way to chill OR do you have other ideas??

Flexible lines so the mashtun can tip, going to try and find some stainless wire wrap or similar instead of cable ties..

The Mashtun inlet comes up through the mixer drive shaft through a banjo type fitting then out two 90 tees at the top..

This is a test sparge tube it rotated with the rakes, not sure what i'll run with here, I want something that helps wash out when its tipped also..
