FELIX GLASS SUBSEA DOME FAQ
Hydrostatic Pressure Test for Subsea Dome Port
Hydrostatic pressure test is physical pressure testing to verify the optical dome can withstand its rated water depth pressure before deployment. It is an optional validation step after optical polishing.
How hydrostatic test works
The dome sample is placed inside pressure chamber, pressurized to target pressure (300 bar for 3000m,700 bar for 7000m), hold for specified duration, then inspect for crack, leakage or permanent deformation.
What you get after test
We can issue official hydrostatic test certificate for equipment qualification, third-party audit and marine project documentation.
Important limitation
Hydrostatic test only validates static pressure resistance. It cannot fully replicate cyclic pressure, vibration and marine biofouling in real deep ocean environment, so sufficient safety factor is still required.
FAQ
Q: Is hydrostatic test mandatory for all dome orders?
A: No, it is optional. FEA simulation is mandatory for all 7000m dome before machining.
Q: Can you test flanged dome port?
A: Yes, integrated one-piece flanged domes can go through hydrostatic pressure test.
Q: Will the test damage the optical surface?
A: Properly performed pressure test will not damage dome optics.
Q: What certificate is available after testing?
A: We can provide formal pressure test report and certification document.
