5.Standard Dome vs Integrated Flanged Dome Port | Subsea Dome Comparison
FELIX GLASS SUBSEA DOME FAQ
Standard Dome vs Integrated Flanged Dome Port
Two major dome mechanical designs for subsea imaging systems: standalone standard dome and monolithic integrated flanged dome port. The core difference is assembly method and sealing interface count.
Standard standalone dome port
Standard hemispherical dome requires separate retainer ring to clamp it onto housing. It works well to retrofit existing housings. More assembly steps and one sealing interface between dome and retainer.
Integrated flanged dome port
Dome and mounting flange machined from single optical blank. Direct bolt-on installation without retainer ring. Only one sealing surface on flange face, fewer leakage paths. Best for new housing design and high reliability missions.
Side-by-side summary
- Standard dome: lower machining cost, fit existing retainer housing, slightly higher leakage risk under cyclic pressure
- Flanged dome: higher machining cost, simpler assembly, lower leakage risk, custom flange bolt pattern required
FAQ
Q: Which one has lower leakage risk?
A: Integrated flanged dome port has fewer sealing interfaces, so lower leakage risk.
Q: Can flanged dome fit my existing housing?
A: Only if flange OD, bolt circle and O-ring step match your housing drawing.
Q: Both support 3000m and 7000m rating?
A: Yes, we can produce flanged dome for both depth ratings.
CTA: Share your housing drawing, we advise whether standard or flanged dome fits better.
