A shrader valve is the valve the tires of a car have to put air in them.

Ok guys, I went to the tank factory, and my friend calculated the stress factors and all that for the shock absorbers and they don't pass, so that means you were right Gippeto. He recommended galvanized pipe of about 1 1/2" to 2" with threaded caps. Im going for that. Those tanks look beautiful Jack...

I have several issues here: One, I cant find the correct kind of steel used in the shock absorbers, therefore I can't find the variable to work Barlow's formula for the strength of the "tank". Two, My skills at math stink to say the least. I might even screw up adding 2+2. Three, I know for a fact t...

The factory makes propane tanks. Well now with a measurement of 0.039 I get only 468 psi for the max pressure. Now I'm not only worried but also lost LOL. What should I do? According to what you have said, welding is not the answer. I find it hard to make threads on the inner part of the absorber, s...

Um... Let's see... I used a safety factor of 4. Math and I aren't very good friends though, but you say 120(?) I don't know if you made a typing mistake. What I'm using as a tank is the hidraulic part of a shock absorber. I cut the top part, took out the piston and all the valves, together with an i...

Yes is a quick connect valve that looks very much like the one on the bottom right. The relief valve is fully adjustable, starting at 30 psi up to 100 psi if I'm not mistaken. As a trigger, if you take a close look at it, I designed a piston that slides inside a small brass tee (inside the tank) tha...

Um.. I plan to put a quick release valve for the tank. the rest is going to be welded.
I just checked Barlow's law, and these are the results:

According to Barlow's law, P equals 1440, but just in case, re check for me please. These are the figures:

T = 0.12"
D = 1.5"
S = 9000 psi.

Hahahaha..

Naaah not titanium, but it should withstand a lot of pressure. It's a shock absorber and they do take the weight of a car and maybe more when the car hits a pothole without busting.

Let's see..
According to my calculations the tank should hold close to 500 psi, hopefully more, as it was designed to withstand more than 1 ton of hidraulic pressure.

Well, finally someboby wrote something related to the design lol.

Hi everybody, this is my first post here, so have as much mercy as possible please. Ok as a curious person, I found a post on the web "Piston Valves Explained Visually", and I used the animations to finally understand the whole concept of pilot-chamber-piston relationship. Together with an instructa...
