Homebuilt Tank
Hello guys.
I want to make a high pressure tank for my 2260 to convert it into a PCP. I think it won’t be working over 2000-2500psi but I am a bit worried because I haven’t made a high pressure tank before. Have you?
It’s gonna have a 23mm outside diameter.
What material should I use? I have been told to use precision tube. Is that correct? How thick should it be?
Should I consider something about threads etc?
Should I hydro-test it before use it? And where can I do that?
Thanks a lot 8)

Personally, I’ve got no experience with dive shops, but from what I do know, I can’t imagine there are many who’d be dumb enough to fill a homemade tank… at least here in the US.
I’m not knocking your urge to create, that’s always a good thing… but they don’t call them “high pressure” tanks for nothing.
Hello Voltar.
I am George from Greece and I have posted before. 8)
My equipment doesn’t exist at the moment. Next month I’ll own an Alfa lathe, the AL 300 x 180 Variable Speed model.

What do you think about that? Is it a good lathe?
Where should I go to have my assembly hydro tested? Dive shops do that?

Welcome, please, who are you and who are you on other forums?
you want 7/8″ x 0.065″ wall 4130 DOM tubing.
properly anchor teh valve and fill system
Hydro test the assembly to 150% working pressure
What equipment do you have access to and know how to operate?
Good luck
Be safe
Walter….
BTW, I’ve built a few 🙂

Not sure if this is relavent but i got some stainless high pressure tube a while back at 1.25″OD. As it was sold to me as hp tube a certificate was available to prove the spec of the material, ie its burst and operating pressures.
If you buy from a steel stockholder it should be able to supply you with the spec sheet of the tube.
Hope this helps, Sean.
