I've been searching on the board the last few days learning all I can before my first brew. In my searches I stumbled across a couple threads that describe a DIY approach to using steam for a heat source. I only found two references to pressures used in the vessel and both were 15 psi.
I work for a company that assembles and repairs safety valves for anything from a Mom and Pop operation boiler to 4000 psi boilers at power plants. I'm not completely up to speed on the NBIB and ASME codes but 15 psi is the magic number where coded valves are required. The code may not apply to vessels under a certain size, like the 5 gallon keg I read about, but I'm not sure. Just to be on the safe side though I'd STRONGLY RECOMMEND backing the pressure off to 14.5 psi and here's why. If you blow your house up and the insurance company determines the cause and more importantly that you were using node code equipment in a coded application the claim will be denied.
Like I said, I'm not intimate with the code so I'm not certain that it applies to vessels under a certain size but why chance it for .5 psi.
