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
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.
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.
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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lVYeFPhX1OE.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).
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
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.
