HYDRAULIC PRESSURE TESTING + AIR
HYDRAULIC PRESSURE TESTING + AIR
(OP)
Kids studying to be ME told me they want to test a steel cylinder by filling it 90% to 95% with water and 10% to 5% with compressed air. The idea being that compressed air is readily available in their dad's garage, and that by filling only the 10% ~ 5% volume with air it is less dangerous. I told them that pressurized air at high pressure will be dangerous even in a small volume. Can you second my opinion before they hurt themselves ?





RE: HYDRAULIC PRESSURE TESTING + AIR
So I concur with your evaluation, filling the tank with water, before adding air will make it less dangerous, but it is STILL dangerous.
B.E.
You are judged not by what you know, but by what you can do.
RE: HYDRAULIC PRESSURE TESTING + AIR
why not to get a hand pump. I can test to 5,000 psi with a cheap hand pump.
don't kill yourself
RE: HYDRAULIC PRESSURE TESTING + AIR
If they want to use air, then create a separate hydro tested vessel which you fill with water and then pressurise with air at the top, making sure that you only use that much water in the test.
