Got the new brewery put together last weekend, soon as the weather warms up a little can get out and give this a go.
Mostly used 2 in steel, but you can see for your self below. I plan to do a direct heat recirculation, but have option for a HERMS.
82 Qt Bayou Classic for Boil
62 Qt Bayou Classic for HLT
15 gallon Boilermaker for Mash
All bayou burners, got 1/4 pipe tread orifices from Tejas Smokers.
Ajustable gas regulator with pressure valve, can go 0 to 75 psi
(Although don't need more then 20 even with all burners full open, I would bet 75 would freeze the valve in the 2 mins your canister emptied out)
All solid black pipe for gas, looks cool, but a lot of work to get it dialed in. If I was going to build again, I would put in adjustable and removable burner mounts. As it is, you have to get a friend to help take apart if there is a leak. (Fingers cross I don't get one, had to tweak on connection, you can see the valve is off center on the 1st burner.)
Left 1 tee incase I want to add in a set of pilot lights. Not worrying about it too much now, if it isn't a pain to light I am just going to deal with. I have the pilots put together, but at this point I just want to start brewing.
Only thing you don't see if the norprene high temp tubing and stainless disconnects. Also a whirlpool style sparge arm, copper from mash to boil and whirlpool immersion chiller.
