Cool video man! Wondering if you think that ultrasonic testing will take over from hydrostatic. Considering it is faster and more accurate, and no removal of the valve or emptying of the cylinder required
whta is the name of the gauge to check the surface rust and how do you used that? how deep should the pitting rust be that will result to it failing. what will happen to cylinfer if it failed the hydro test.? how important is the water jaket?coz here in the philipines we dont use those.
hi im writing from chile nice video I have my own hydrotest , i would like to know more info about digital pressure manometer and where can I buy one. How do you get the calibration? thank you
I still don't understand how the process works. The tank is filled with water and submerged in another sealed tank but from there, I don't know where the pressure is applied. Is it possible to show another video that explains every step of the way? Or can you recommend a video that shows how all this works?
Alec Peirce has a good video on the process: ua-cam.com/video/lVYeFPhX1OE/v-deo.htmlsi=2pQtphpYGmMxp7ny Tank pressurized, it expands and forces water out of the test chamber. That water is collected, volume measured (159 in this video). Then pressure released, that excess water is sucked back into the test chamber and what's left it measured (3 in this video).
Hydrotesting is the single most damaging process you could do to these cylinders. Water and steel, not properly drying it on the inside. Add oxygen from the air, and there goes your tank. If you just kept it dry... pretty much all tanks would last 100 years.
These cylinders have to be tested regularly. Using liquids is the most safe way to do it, or so I'm told. So, any suggestions with what to replace the water?
@@SeersantLoom I know the requirements, but if the cylinders are not properly dried, the testing alone is severely limiting the lifetime of the cylinders.
Shouldn't you let the water stabilize for 8 hours at least??I'm pretty sure the water inside the cylinder should be at room temperature before it gets hydrotested. And its a cylinder not a tank.
Im in school for respiratory and i thought this video was pretty cool! Thank you
Very interesting. Good job on the video. Thank you!
this tank will probably out live us all
😂
Very cool!
Thanks for the video.
What did you stamp on the cylinder???
You talking about the Swaztika? I saw that too lmao

Super cool! Did you restored?

What cylinder clamp are you using to remove the valve?
Can you do a shop tour?
That symbol is not for good luck, it is a manufacturer's mark of some kind, well known in the industry
Very cool video 👍🖖

Those are called pressure transducers, in my country we have to recertify them every year by an independent company.
2Q. are the test to be different if cylinder use oxygen or nitrogen gas
No, doesnt matter the gas as long as you keep the work pressure

From what I saw looks like the he is measuring the water pushed out of the tub thing. as the cylinder expands under the test pressure .
Why percentage 1.8 is meaning pass what we doing if result become 2 or 4
All 3 series cylinders have a 10% margin.
I've hydo tested a LPG tank from 1928 haha

I bought one at an estate sale for $20 bucks are they worth anything
I wanted to exchange it for a full aluminum to use
