just wanted to know a few basic facts on making airtanks.
im going to be making two airtanks out of steel tubing about 10cm in diametre and around 45cm in length. im planning on just welding it all together to keep it airtight but what thickness steel do i need and all that in order to keep these things safe and sturdy? thanks.

you can make a tank any shape you want. some off-roading jeeps have air tanks made out of the tubing that they use for their bumper, just in case they get a flat way out in the middle of no mans land. just make sure your welds around the threads and ends are good.

you are only running 150-200 psi. you will be ok with a square tank or whatever shape you want.

There is nothing wrong with building your own air tank. I wish more people would, its gettin borring lookin at the same tanks all the time. Especially just black ones thrown in the trunk like all my old cars lol.

1/4" is overkill!

1/8' is the thickness of most car frames. It wil be ok for a tank.

You have to measure the area, then find some convesions on the internet to calculate the area into gallons. I Did it before a couple times.

yeah, 1/4 is kinda thick. that would be a heavy ass tank.. never thought about a propane tank. lemme know how it works out. where you gonna put it? i got a frontier too and was wondering how you could make 40 gal tank look good...

Square tanks will expand and flex in the center.. Not a good thing!
