The basics
What is hydro-testing?
We pressurize your cylinder past its working pressure to prove it can still take it. Here’s the short version.
🎈
Metal stretches
Like a balloon blown up over and over, a tank grows a little with every pressure cycle — even just warming in the sun.
🔬
Wear adds up
Stretching plus pitting and corrosion means tanks slowly get more dangerous to use over time.
💧
Water, not air
We test with water, which doesn’t compress — so if a tank fails, the release isn’t explosive. Safe for everyone.
✅
Proven safe
Pass the test and we’ve proven your tank still holds the pressure on its name plate.
