Someone attempted to clean one using an unregulated air compressor, so it was pressurized WAY above the maximum pressure that those are rated for.

Apparently that isn't the case for all of the breweries that have had issues.

FWIW, we had one fail about two years ago at normal working pressure (10-12 psi). I believe that in that case the seam had been weakened by repeated hot/cold cycling.

I have 77 of them. So far so good. But I am concern.
It is newer a good idea to overpressurized any pressure vessel.

I have 6 3BBL serving tanks and 2 5BBL jacketed fermenters from the GW Kent micro line. None of it is in use for production yet but I have water tested all of it. The serving tanks were pretty much perfect when they arrived. A few of the welds were a little rough and there were some fairly insignificant surface scratches inside the tanks. The fermenters were more of the same, except for one of them which had some sort of a weld burn-through on the bottom of the cone. This causes a small, but significant leak from the jacket. GW Kent has offered to pay for a local welder to repair the hole, but of course finding a qualified stainless welder in my area who won't end up making the problem a hell of a lot worse is a challenge.

The 3/4" MPT threads on the jacket for attaching glycol in/out are atrocious too. A couple of them look like they tapped them more than once. They all had bits of metal and pipe dope (I assume from the back-gassing process during manufacture) in them. And they were a challenge to get fittings to mate into, in the end, lots of teflon, elbow grease, and finger crossing made them water tight.

BUT as mentioned, often times, you can't beat GW Kent's lead time. I had the serving tanks within 4 weeks of ordering them and I had the fermenters within a week of ordering them. They are often sitting on tanks/fermenters/whatever up there in Michigan, sometimes from other breweries' who end up not being able to purchase the items, sometimes just timing I guess.

Wow... thanks for those links.  I was unaware of the low-pressure failures.

Do you happen to know the difference between their standard and "micro" tanks?

Here's what I got back from GWK:
Quote
Micro-fermenter use our econo butterfly valve, non shadowless manway, and cladding on tank is thinner stainless steel.  There are detail finish on tank that is done with less labor for saving also.

I heard that their Micro line is a mixed bag. Made in China.
Regular stuff is made in Taiwan.

In our price range, we'll be getting Chinese tanks one way or another. For what an American manufacturer would charge, we can replace them all at least once.

At this point I'm leaning toward Glacier, but I have three months to decide.

How many times a week do you brew, Keith? In looking at the numbers of units to be sent out, it seems mind-boggling to me that I'd be able to push 9,000 bottles/cans PER BATCH, meaning I'm sending out nearly 60,000 bottles/cans per month. Where does it all go? Boggles the mind.

Maybe you've already mentioned it in this thread, but what is your annual production goal with the new 30BBL fermentors?

Also, what size is your brewhouse?  I've seen some smaller micros that have, say, a 20bbl brewhouse with 40bbl fermentors.  How would you utilize this setup?  Would you brew two 20bbl batches and put them both in a 40bbl fermentor?
