Obviously you can do what you want - but please reconsider NOT using an uncertified tank. They don't just go bang. his is one heck of an explosion - think big. Way back in the '60s, Richard Petty had a cousin killed at a race when a little 2-3 Hp version blew - and it did a lot of collateral damage. Side wall thickness doesen't have much to do with the tank pressure capacity as there are many grades of steel and stainless - and if it is used in the wrong application......or has an incorrect weld spec for major pressure, i.e. 150 and up, it will not work. Think safe - if not for you, then anyone nearby.
